Abstract
Current intensive agriculture system faces a major challenge to achieve higher production while
supporting soil health and biodiversity. Among the livestock, cow has a prominent place in our country.
For millennia, cow dung has been used for several purposes and served as a source of cheap fuel, housing
material and insect repellent. Panchgavya that consisted of five ingredients from cow i.e. dung, urine,
milk, curd and ghee is gaining attention of researchers for its various health benefits and its potential as
therapeutic agent against many human diseases. Moreover, the cow dung possesses myriad batteries of
microbes that exert their beneficial effects through production of metabolites. Since the ancient times,
cow dung has also been used as an vital source of organic fertilizer and in the production of biogas.
However, with modern civilization, this natural bioresource is forgotten and its exceptional qualities
largely ignored. This review article is an attempt to gather all the scientific research findings that support
the use of cow dung and its multifarious role in various sectors.
Keywords: Cow dung, bioresource, Panchgavaya, economy
Introduction
In India, total cattle population is 192.49 million (Livestock Census 2019) [1]. Cows constitute
paramount resources for dairy and agriculture sectors in India. Aimed to increase the
indigenous breed of cows ‘Rashtriya Gokul Mission’ was announced in 2014, by the
Government of India. Kamdhenu or Indian cow (Bos indicus) is revered as sacred animal by
Hindu (Kaushik et al. 2016) [18]. Cow dung is an inexpensive and economically viable option
and is locally available in the rural areas of India (Randhawa and Kullar 2011) [38]. The dung
coated mud walls and floor signifying its importance as a disinfectant and also provide
insulation during summer and winter months. Even today, cow dung cakes are used as fuel in
many rural areas. Since the ancient times, cow dung in India has been considered to be very
sacred for religious ceremonies as well. For centuries, cow dung has served myriad purposes
particularly in Indian rural households serving as a pivotal source of fuel, repelling
mosquitoes, flies and as a sanitizer. Additionally, ashes of burnt cow dung are applied for
cleaning kitchen utensils (Munshi et al. 2018) [27].
Cow dung is also serves as manure or agriculture fertilizer and escalates soil fertility
significantly. Cow manure is a cheap and prime source of renewal energy in form of Biogas in
future due to shortage of other non-renewal sources of energy like coal, oil and gases.
Livestock waste composts along with minimum inorganic fertilizer as a soil amendment in
low-input intensive farming are a viable agricultural practice to enhance soil fertility and
productivity and to further lessen soil degradation (Das et al. 2017) [8]. With this background,
it is evident that cow dung has been an indispensable and multifarious component in Indian
domestic, agricultural and ayurvedic arenas since the time immemorial. This review is an
attempt to develop an insight into various traditional and scientific role that is possessed by
this un-deciphered bioresource.
Cow Dung: A unique cocktail of microflora
The reticulorumen in ruminants in the site where digestion of structural carbohydrates such as
cellulose and hemicellulose can take place to any substantial degree through microbial
fermentation. Microbes in the reticulorumen chiefly include bacteria, protozoa, fungi where
bacteria and protozoa are harboured largely. From the perspective of a cow, a major benefit of
having rumen is to provide a home to bacteria that possess the enzymes require to break the
β1-4 linkage between the various sugars that make up cellulose and hemiceullose (Reece et al.
2015) [40].

The reticulo-rumen contains batteries of specialized anaerobic
microbial populations responsible for the fiber breakdown,
which is affected by biochemical and microbial characteristics
of the rumen (Tesfaye and Hailu 2019) [49]. Lower part of the
gut of the cow comprises of several microorganisms including
Lactobacillus plantarum, Lactobacillus casei, Lactobacillus
acidophilus, B. subtilis, Enterococcus diacetylactis, Bifido
bacterium and yeasts (commonly Saccharomyces cerevisiae)
possessing probiotic activity (Ware et al. 1988) [54]. Since,
livestock practices differ from one individual to another and
from one geographical site to the other, eventually influences
the microbial structure of manure released by the animals
(Manyi-Loh et al. 2016) [22].
Cow dung is excreted by herbivore bovine animal species that
consists of undigested residues of consumed matter which has
passed through the cow’s gastrointestinal system (Teo and
Teoh 2011) [48] which is acted upon by ruminal microbes.
Cow dung contains organic matter and fibrous material like
cellulose, lignin and hemicellulose that has passed through the
cow's digestive system (Rajeswari et al. 2016; Munshi et al.
2018) [37, 27]. Generally, cow dung is composed of about 80%
water and supports a matrix of undigested plant material that
is rich in nutrients, micro-organisms, and their byproducts
(Sharma and Singh 2015) [41]. Cow dung is a mixture of dung
and urine, usually in the ratio of 3:1 that encompasses crude
fibre, crude protein, cellulose, hemicellulose and 24 types of
minerals such as N, K, S, traces of P, Fe, Co, Mg, P, Cl, Mn,
etc. (Nene 1999; Swain and Ray 2009) [28, 47]. Cow manure
contains essential micro and macronutrients and considered as
potential fertilizer for crop growth and it is an economic
substitute for synthetic fertilizers (Kiyasudeen et al. 2015) [19].
Chomini et al. (2015) [7] demonstrated that digested cow dung
had the highest percent increase for four major amino
acids viz threonine, proline, glycine, alanine. Cow dung
contains diverse microflora that comprises of about sixty
bacterial species including Bacillus sp., Corynebacterium sp.,
Lactobacillus sp., few fungal sp., (Aspergillus and
Trichoderma), about 100 species of protozoa and 2 yeasts
(Bhatt and Maheshwari 2019) [6]. Teo and Teoh (2011) [48]
recognised five distinct morphologically and physiologically
bacterial isolates from cow dung where all the isolates
produced protease, lipase and esterase lipase. In a study,
Stevenson and Weimer (2002) [46] identified a strain as a
member of the genus Trichoderma and designated strain A10,
isolated from cow dung and that initially produced about 0.4 g
ethanol l1.
Recently Rawat et al. (2019) [39] conducted a study on
indigenous cows Sahiwal and reported a significantly higher
population of microorganism in lactating cow dung as
compare to heifer. In this study total bacterial population in
heifer and lactating cow was found to be 16.17±0.7 and
20.16±1.58 cfu/g respectively. The yeast and fungi were
(5.46±0.43 and 7.73±0.47cfu/g) respectively. In a study,
Kiyasudeen et al. (2015) [19] collected three cow dung samples
from three different farms with different feeding regime and
reported that fresh cow dung samples are rich in microbial
colonies. It was reported that total cfu/g of bacteria in CD2
(2.84±0.01x10 cfu/g) was significantly higher than CD3
(2.47±0.01x10 cfu/g) and CD1 (1.78±0.05x10 cfu/g) whereas
total CFU/g of fungi in CD3 (2.78±0.01x10 cfu/g) was found
to be substantially higher than CD2 (2.36±0.04 x10 cfu/g) and
CD1 (2.14±0.01 x10 cfu/g). It was recommended to add
nutrient rich supplements to the cows along with grass as
major diet to obtain cow dung rich in nutrients. Girija and
coworkers (2013) [12] made an attempt to probe the diversity
of microbes present in cow dung using 16S rDNA sequencing
approach and detected phyla such as Bacteroidetes, firmicutes
and proteobacteria which efficiently degrade cellulose, chitin,
lignin, xylan. Their findings also showed detection of
Acinetobacter, Bacillus, Stenotrophomona and Pseudomonas
species. Lately, Tomar et al. (2020) [51] attempted to isolate
bacteria in cow dung using nutrient agar medium (NAM). In
this study, they concluded that numerous species of gram
positive bacteria were present in cow dung which included
spore forming Bacillus spp., Enterococcus, Diploccocus and
gram negative bacteria like - pseudomonas. Cow dung serves
as a purifier of all wastes in the nature, is a rich source of
microflora that can be utilized as probiotics, live microbial
food supplements modifying the intestinal microbiota
(Sharma and Singh 2015) [41].
Cow dung: An untapped eco-friendly bioresource
Energy is one of the foremost factors to global prosperity.
With rising population, there is a steady increase in the global
demand for energy. The scientific research for renewable
sources of energy is essential owing to limited reserves for
fossil and coal energy. Furthermore, the high dependency on
fossil fuels as prime energy source has caused climate change,
environmental pollution and degradation, hence leading to
health problems in human (Aremu and Agarry 2012) [4]. The
return-to-renewables will help to lessen climate change is an
excellent way but it requires to be sustainable in order to
ensure a sustainable future and bequeath future generations to
meet their energy needs (Owusu and Asumadu-Sarkodie
2016) [31]. Using the process of anaerobic digestion, gases are
derived from a wide range of organic wastes such as biomass
waste, human waste, animal waste and used as source of
energy (Putri et al. 2012) [33]. Biogas produced from
renewable source can be one of the response for future energy
production (Ambarsari et al. 2018) [3]. Biogas, is a mixture of
diverse gases produced by anaerobic fermentation of organic
matter from methanogenic bacteria (Sharma 2011; Gupta et
al. 2016) [42, 15]. Biogas normally contains 50% and above
methane (CH4) and other gases in relatively low proportions
namely, CO2, H2, N2 and O2 (Kalia et al. 2000) [16]. Cow dung
is the main source of biogas or gobar gas production in India
(Gupta et al. 2016) [15]. Cow dung as animal waste possess
great potentials for generation of biogas and its use should be
encouraged due to its early retention time and high volume of
biogas yields (Ukpai and Nnabuchi 2012) [52].
Mixing of cow dung with manure obtained from other species
has been investigated by many researchers. Previously, effect
of mixing pig and cow dung on biogas yield was evaluated
(Kasisira and Muyiiya 2009) [17]. The study showed that co-
digestion of cow dung with pig manure increased biogas yield
as compared to pure samples of either pig or cow dung. Rabiu
et al. (2014) [34] studied the effect of cattle manure collected at
different time inoculated with rumen fluid of cattle on biogas
production at mesophilic condition. Their study revealed that
if used between the ranges of 2550% of rumen fluid, the best
performance biogas production was observed. Furthermore,
cattle manure collected after 12 h of defecation was recorded
with the highest biogas production in comparison to 0 h and
24 h of cattle post-defecation. Similarly, in another study it
was documented that cattle rumen fluids produces more
biogas than the goats. It was further detailed that the increase
in the biogas production at certain level was in respond to the
amount of rumen fluids added into the mixture (Rabiu et al.
2014a) [35]. Poultry litter from broilers mixed with an
optimum proportion of cow dung was found to be a substrate
with a high potential for biogas generation by anaerobic
digestion (Miah et al. 2016) [23].

With rising population, there is a tremendous pressure on
agriculture to enhance food production to meet the demand.
However, imprudent use of chemical fertilizers has led to the
decline in soil fertility. Due to hike in prices of chemical
fertilizer and their non-efficient role in long term sustainable
production, the application of organic manure including cow
dung is required for raising maximum productivity in
sustainable way with better soil health. It is an effective tool
to ameliorate physico-chemical and biological properties of
the soil with higher yield of plants in sustained basis without
altering the fertility of soil (Raj et al. 2014) [36]. Bacteria
isolated from local breeds of different bovine animal have
shown potential to be used as plant growth promoting bacteria
(Aiysha and Latif 2019) [2]. Addition of cow dung enhances
the organic carbon content of degraded soil that may further
lead to the increasing activity of beneficial soil microbes as
well as the fertility status of soil by increasing the availability
of nutrients for the plants from soil (Zaman et al. 2017) [55].
Solomon et al. (2012) [45] compared the effects of organic
manure and inorganic fertilizer (N.P.K.) on growth of Maize
(Zea Mays L) and concluded that cow dung manure can be
used in the absence of N.P.K. fertilizer. Zhang et al. (2020)
[56] reported the suitability of cow manure fertilization for tea
plantation and highlighted that application of cow manure can
not only improve the variety of soil bacteria, but also
effectively regulates the structure of soil bacterial community
in tea plantation. In similar study, cow dung application have
been found to be increased the total N, available P,
exchangeable K, Ca, Mg, available S, Zn and B contents in
soils and biomass yield of stevia (Zaman et al. 2017) [55].
Studies have suggested that exposure to the smoke of
mosquito coils can pose significant acute and chronic health
risks (Liu et al. 2003) [20]. Cow dung has been studied for it
properties as mosquito repellent. Cow dung is a cheap, eco-
friendly herbal repellent with long lasting protection that is
safe for human and domestic animal skin with no side effect
and no feedback of environmental ill effect, as a substitute to
synthetic chemical repellents (Mandavgane et al., 2005;
Mukherjee and Ghosh 2020) [21, 26]. Cow dung alone or in
combination with other mosquito repellent plant species,
could effectively used for the preparation of mosquito
repellent products (Mukherjee and Ghosh 2020) [26].
Cow dung: a multifaceted biomass for bioremediation
In the last few decades, industrial revolution has caused an
exceptional release of hazardous compounds into the
environment, jeopardising the environmental balance of our
planet (Godambe and Fulekar 2016) [13]. The presence
of inorganic pollutants such as metal ions in the ecosystem
pose a major environmental problem (Ojedokun et al. 2016)
[29]. Bioremediation methods use naturally occurring
microorganisms to detoxify man-made pollutants so that they
change pollutants to harmless products that make soil fertile
in the process (Randhawa and Kullar 2011) [38]. Cow dung ash
is a bio-organic waste and absorbent and is an excellent water
purifier. Entire harmful bacteria are killed just by adding a
pinch or two of cow dung ash in few liters of water (Thakare
et al. 2019) [50]. The adsorption abilities of cow dung by using
aqueous solution of chromium has been investigated and it
was concluded that adsorption highly depends on pH, time
and initial concentration of chromium. Cow dung exhibited
maximum adsorption at an acidic pH (Mohan and Gupta
2014) [25]. Few years back, Godambe and Fulekar (2016) [13]
established a unique strategy for biodegradation of one of the
most potent and widely accumulated hydrocarbons pollutant,
benzene using indigenous source of cow dung. They
documented that cow-dung harbour a range of microbes that
show a great potential to degrade benzene. These bacteria in
isolation or as a consortium utilize and multiply in presence of
high benzene concentrations. Similarly, it has been reported
that cow dung ash can be used for the removal of dyes from
the waste water by adsorption (Sharma and Patel 2017) [43].
Similarly, bio-waste cow dung ash is an efficacious adsorbent
in purifying biodiesel analogous to traditional water washing
technology (Avinash and Murugesan 2017) [5]. Recently,
Ojeme and coworkers (2019) [30] conducted batch experiments
to investigate the removal of Pb(II) ions from aqueous
solutions using chemically and thermally activated cow dung
(CTAC) ash and non-chemically but thermally activated cow
dung (NTAC) ash under various experimental conditions and
reported cow dung as a potent absorbent as shown by its
efficacy for Pb(II) ion removal.
Cow dung: A natural therapeutic gateway?
Cow dung has been referred to as a “gold mine” owing to its
vast applications in the arena of agriculture, energy resource,
environmental protection, and therapeutic applications
(Randhawa and Kullar, 2011) [38]. The people frustrated from
the heavy medication of allopathy are now using cowpathy
drugs and being benefited by the panchgavya products for
numerous diseases (Dhama et al. 2005) [10]. Previously, in a
study it was documented that cow dung extracts exhibited
partial antimicrobial property against human pathogens.
Furthermore, the Indian cow dung extracts possess greater
antimicrobial activity in comparison to other cow dung
(Rajeswari et al. 2016) [37]. In a study, Mishra and coworkers
(2014) [24] revealed that cow dung extract possess
antimicrobial properties, that can be used to counter certain
pathogenic diseases and other ailments. In another study,
dung obtained from Indian cow exhibited superior
antimicrobial activity compared to Jersey and Holstein cow
dung. The extracts of the Indian cow dung showed
antimicrobial activity against test organisms like Klebsiella
pneumonia and Escherichia coli (Rajeswari et al., 2016) [37].
Interestingly, cow dung has been used as the economical
substrate for the production of fibrinolytic enzyme
(Vijayaraghavan et al. 2016) [53]. Cow dung is a home remedy
used by many African communities to manage burn wounds
and for its validation. Gololo et al. (2019) [14] suggested that
the presence of proteases in cow dung could be one of the
contributing factors towards its efficiency in managing
traditional African burn wound. Cow dung has been
documented to act as skin tonic and on mixing with crushed
neem leaves and smeared on skin, it demonstrates good
results for boils and heat rashes. Cow dung also used as tooth
polish and relieves toothache (Kaushik et al. 2016) [18].
Traditionally, Panchgavya (Sanskrit for a blend of ‘five
products from cow’) that consisted of five ingredients from
cow i.e. dung, urine, milk, curd and ghee has shown
numerous health benefits and possess many therapeutic
properties against many ailments (Rajeswari et al. 2016) [37].
These five products are either used individually or in
combination with other herbs, often referred to as Cowpathy
or Panchgavya Therapy (Dhama et al. 2013) [9]. Panchgavya
appears to be useful for the diseases such as cancer, acquired
immunodeficiency syndrome (AIDS) and diabetes (Gupta et
al. 2016) [15]. Paliwal et al. (2013) [32] determined the efficacy
of Panchgavya on Spontaneous Motor Activity, muscle tone
and pain on albino rats through administration of Panchgavya
(50 mg/rat, orally) daily for 30 consecutive days. Their
findings indicated a gradual increase in the muscle tone
activity and analgesic activity in terms of reaction time.

Undoubtly, with these preliminary studies it is evident that
cow dung can offer alternate low cost therapy having no side
effects, however, there is a meagre scientific data to validate
these claims and assertions before establishing efficacy of
cow dung and its role as a prominent therapeutic agent. For
this proper support and more in-depth probe should be
undertaken by the scientists, researchers and clinicians/
physicians that will ultimately foster confidence in the public
about its good virtues.
Estimates of production of dung
Dikshit and Birthali (2010) [11] estimated the total wet dung
production (about 562 million tonnes) for the year 2003, out
of which cattle contributed around 60% while buffalo
contributed around 40% of total dung due to difference in the
population share in total bovine. The evacuation rate of
animal (average dung production/animal/day) mainly depends
upon certain factors like quantity of feed intake, type of feed
and physiological and environmental factors. It also varied
among different species, age-groups and functional
classification of bovines.

Probable economy of dung
As the largest livestock population of the world, our country
is also facing international scrutiny for its greenhouse gases
emission. Therefore, some serious measures should be taken
on the issue. We should try to convert our negative into
positive. Dung can be utilized as the organic fertilizer instead
of chemical fertilizers in the agricultural land. Setting up of
biogas plant in the rural area for the prevention of fire wood
usage in the domestic work can also reduce the problem of
increasing pollution. Conversion of dung into the valuable
products such as vermin-compost will not only add-up in the
income of the farmer but also replacing it with chemical
fertilizer will improve the soil fertility and will enrich the
environment. The conversion rate of organic matter (75-80%
moisture) into vermicompost is about 40-50 % (Sinha et al.
2010) [44]. If the total dung estimated could have been used for
vermicomposting, we would had produced around 314.955
million tonnes of vermin-compost generating income
(Rs.10/kg) of Rs. 3,149 billion/- (approx.).
Conclusion
Being largest total bovine population in world but reasonably
low per animal productivity, only milk cannot be a way to
improve economic status of small scale farmers. Dung has
multifaceted properties that were largely ignored, can be a
vital player in improving the income of the farmers in today’s
time. In the present work, scientific studies published in
relation to the multiple usage of cow dung were reviewed and
it can be concluded that owing to its rich microflora and many
properties cow dung can serve through multiple ways and
thus, it is a boon for sustainable livestock farming and can be
viable alternative for non-renewable energy source.

Indigenous cows have a high potential for organic manure, which is required for organic farming, and in the near future, and will be the backbone of organic farming and India's agricultural economy. It increases plant resistance to pests and diseases, encourages plant growth, and promotes other beneficial activities such as sulphur oxidation and phosphorous solubilization. Lactobacillus plantarum, Lactobacillus casei, Lactobacillus acidophilus, B. subtilis, Enterococcus diacetylactis, Bifidobacterium, and yeasts (commonly Saccharomyces cerevisiae) are found in the lower part of the cow's gut. Cow dung contains beneficial microflora, including bacilli, lactobacilli, cocci, and a wide range of known and unknown fungi and yeast. Under NABARD sponsored organic farming project executed by ARF, it was observed that vermicompost made out of cowdung improves the texture, water holding capacity, organic carbon content and microbiota of soil for enhanced productivity per acre of land. This review highlights the significance of indigenous cow dung and its microbes in agriculture, industry, pharmaceuticals, and environment.

In India, cow dung is widely utilized to create formulations that serve as effective plant growth enhancers with antimicrobial properties. The cow dung-derived handmade paper manufacturing process produces two waste-liquor streams, a Raw Liquor (RL) produced through the dewatering of the cow-dung slurry and a Black Liquor (BL) produced during the soda pulping of dewatered cow dung. The present study explored the potential of these waste streams to be used as plant biofertilizers for germination and cultivation of Vigna radiata seeds (mung bean, IPM-02-03 variety). An in vitro assay for seed germination efficiency and a pot study for plant growth promotion (PGP) activity were used to assess this potential. The in vitro assay demonstrated that nutrient-rich RL, with its 100% seed germination efficiency (better than the 85.7% of tap water) was an effective biofertilizer for seed germination. In contrast, BL yielded poor seed germination efficiency. The pot study showed that water irrigation led to good seed germination, survival, plant rooting and shooting, but it was probably deprived of nutrients for inducing good grain yields. When water was replaced with RL, it was able to replicate the results, but with good grain yields. In contrast, BL produced poorer germination, seed survival and PGP results. The poor biofertilization efficiency of BL was most probably due to the nutrient losses and toxic chemicals produced in the harsh pulping process. The results showed that RL, though considered a waste stream, is sufficiently nutrient-rich to act as an effective biofertilizer for germinating mung bean seeds and promoting plant growth and grain yields.
... Cow dung contains essential micro and macronutrients and is considered a potential fertilizer for plant growth, providing an economical alternative to synthetic fertilizers. The addition of cow dung may increase the organic carbon content of degraded soils, further enhancing beneficial soil microbial activity and soil fertility by increasing the availability of nutrients from the soil to plants [42]. Application of cow dung increases the soil organic matter content, resulting in improved water infiltration and water retention capacity, as well as increased cation exchange capacity. ...

Modern farming systems affect soil health and biodiversity due to the excessive and indiscriminate use of fertilisers, leading to a reduction in soil enzymatic activities, especially mineralising enzymes. It has emphasised the importance of developing long-term, eco-friendly, and environmentally sound alternative agricultural approaches. Organic and natural farming is based on the use of indigenous fermentation technologies, like bioformulations based on cow dung and liquid manures. Cow dung is an essential and integral component of all these preparations and serves as a source of inoculum for beneficial microorganisms. As cow dung harbours beneficial microflora, bioformulations prepared from the products of indigenous cows can offer eco-friendly and sustainable alternatives to soil inoculants and biopesticides. The use of these bioformulations prepared from cow dung is gaining popularity among farmers practicing organic and natural farming to fight against the adverse effects of chemical fertilisers and pesticides without knowing their dosage and time of application, etc. This review is an attempt to collect all the scientific research findings that support the importance of cow dung microflora, cow urine, genomics of cow dung microflora using metagenomics approach, preparations of different bioformulations and their role in plant growth-promoting activity, antimicrobial activity, role in biotic and abiotic stress, and the uses of cow dung in biogas production and in industries which are not covered and fully discussed in previous reviews of organic and natural farming. The major points of review are as follows: (1) Organic and natural farming systems are often associated with traditional or indigenous agricultural practices using cow dung and cow urine as main components to increase soil fertility and microbial diversity. (2) Cow dung has a wide diversity of microorganisms, which help in plant growth, yield, and protection from potential pathogens. (3) Cow dung is a cheap, eco-friendly, and organic source of fertiliser that is being explored for possible other uses. That is why it would not be wrong to conclude cow dung is a “potential unexplored mine of usefulness”.

The coronavirus disease 2019 (COVID-19) is caused by an infection with the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which has infected more than 400,000 people, causing a worldwide pandemic. As of August 15, 2020, as many as 111,455 cases of COVID-19 have been confirmed in Indonesia with 6,071 deaths that have been recorded thus far. Quantitative real-time reverse-transcription polymerase chain reaction (qRT-PCR) has been used as a gold standard to detect the infection of SARS-CoV-2 in many clinical samples due to its sensitivity and specificity. In Indonesia, one of the recommended and commonly used diagnostic kit for COVID-19 was MiRXES Fortitude Kit 2.0E under the license of Singapore's Agency for Science, Technology, and Research (A*STAR), Singapore. Aiming to assess the basic analytical and clinical performance of the MiRXES Fortitude Kit 2.0E, this study prepares serial dilutions of the provided positive control to establish PCR efficiency and to estimate the limit of detection. Moreover, a panel of SARS-CoV-2-positive-clinical samples (nasopharyngeal swab specimens) was tested to preliminarily evaluate the kit's sensitivity on clinical samples. This study is expected to provide valuable assessment information for laboratories that develop routine diagnostic protocols for COVID-19, especially those using the MiRXES Fortitude Kit (A*Star, Singapore).

Background: Cow manure is not only an agricultural waste, but also an organic fertilizer resource. The application of organic fertilizer is a feasible practice to mitigate the soil degradation caused by overuse of chemical fertilizers, which can affect the bacterial diversity and community composition in soils. However, to our knowledge, the information about the soil bacterial diversity and composition in tea plantation applied with cow manure fertilization was limited. In this study, we performed one field trial to research the response of the soil bacterial community to cow manure fertilization compared with urea fertilization using the high-throughput sequencing technique of 16S rRNA genes, and analyzed the relationship between the soil bacterial community and soil characteristics during different tea-picking seasons using the Spearman's rank correlation analysis. Results: The results showed that the soil bacterial communities were dominated by Proteobacteria, Bacteroidetes, Acidobacteria and Actinobacteria across all tea-picking seasons. Therein, there were significant differences of bacterial communities in soils with cow manure fertilization (CMF) and urea fertilization (UF) in three seasons: the relative abundance of Bacteroidetes in CMF was significantly higher than that in UF and CK in spring, and the relative abundance of Proteobacteria and Bacteroidetes in CMF was significantly higher than that in UF and CK in autumn. So, the distribution of the dominant phyla was mainly affected by cow manure fertilization. The diversity of bacterial communities in soils with cow manure fertilization was higher than that in soils with urea fertilization, and was the highest in summer. Moreover, soil pH, OM and AK were important environmental properties affecting the soil bacterial community structure in tea plantation. Conclusions: Although different fertilizers and seasons affect the diversity and structure of soil microorganisms, the application of cow manure can not only improve the diversity of soil bacteria, but also effectively regulate the structure of soil bacterial community in tea plantation. So, cow manure fertilization is more suitable for tea plantation.

SUMMARY. Mankind has for many years relied on home remedies to manage ailments and injuries, including burn wounds. Wound healing is generally regarded as a natural process, with interventions such as ointment application regarded as assisting the process. Amongst other strategies, cow dung is a home remedy used by many African communities to manage burn wounds. The current study was aimed at the detection, purification and characterization of proteases from cow dung as validation for its usage in the management of burn wounds amongst African communities. Cow dung was collected around Pretoria, South Africa, and homogenized with a blender in a phosphate buffer, pH 7. The crude protein was obtained using ammonium sulphate precipitation and purified using size exclusion, anion exchange and cation exchange chromatographic techniques. Enzyme activity was determined using the casein digestion method. The purified proteases were characterized according to temperature and pH as well as substrate specificity. Three protease fractions were purified from cow dung homogenate. Fraction H was found to have an optimum temperature of 40˚C, an optimum pH of 6 and affinity for elastin; Fraction I was found to have an optimum temperature of 35˚C, an optimum pH of 7 and affinity for haemoglobin; and Fraction J was found to have an optimum temperature of 35˚C, an optimum pH of 8 and affinity for collagen. The findings of the study therefore suggest that the presence of proteases in cow dung could be one of the contributing factors towards its effectiveness in traditional African burn wound management.

The effects of microbials dietary supplements on performances and health of the animals, in recent is becoming very critical. Consequently, direct-feds microbials (DFM), is an area of interest of several authors, since last few decades. The probiotics usually, used as DFM for animals are lactic acid bacteria; lactobacillus, streptococci, bifidobacterial, enterococcus and anaerobic fungi species; saccharomyces and aspergillus. Normally, the mechanisms of action of DFM, are modulation of microflora balance in gastrointestinal tract and improvements in digestion and nutrients absorption, sustaining the health of the animals (i.e., through competitive exclusion, secretion of the substances that inhibit the growth or kill and altering gene expression of pathogenic agents) and stimulates the immunity of the animals. Generally, though the effects of host species, types of diet, animal physiological conditions, dosage of probiotics or strain, time of probiotic supplementation and variant strains used, are amongst important factors to be considered, DFM often plays an important role in improvements of milk yield and composition of lactating dairy cows. The DFM of Propionibacterium, Saccharomyces cerevisiae, Lactocbacillus acidophilis, the mixture of yeast products and Enterococcus and combination of L. ecidophilus, L. casei and Enterococcus faecium to dairy cows, significantly improves milk yield and well as the composition. Therefore, DFM, is one of the promising areas of ruminant's nutrition in general or dairy cows in specific, not only because of its nutritional and health benefits to animals, but also due to its negligible residual effects to the animal and animal products.

Batch experiments were conducted to evaluate the removal of Pb(II) ions from aqueous solutions using chemically and thermally activated cow dung (CTAC) ash and non-chemically but thermally activated cow dung (NTAC) ash under various experimental conditions. The optimum pH for the adsorption process using CTAC and NTAC was 5, while the optimum times using CTAC and NTAC were 240 and 180 min, respectively. Freundlich, Temkin, and Langmuir isotherm models were used to analyze the generated adsorption data. The Freundlich model had the highest coefficient of determination (R 2) values that ranged from 0.989 to 0.999. The values of separation factor (RL) deduced from Langmuir isotherm were between 0 and 1 for both CTAC and NTAC ashes for the whole temperature range, which indicated favourable adsorption. Adsorption of the Pb(II) ions followed the pseudo-second-order kinetic model based on the R 2 values that approached unity. Thermodynamic analyses revealed that the ΔH° values for CTAC and NTAC ashes were-8.69 and-11.39 kJ/mol, respectively, which indicated that ion adsorption was exothermic. Negative ∆S° values for the two adsorbents showed that the level of entropy was low at the solid/solvent interface during the adsorption process.

The present study includes the collection, isolation and characterization of microorganisms from the cow dung of local varieties from different places of Dehradun, Uttrakhand, India. Four different strains of bacteria B1, B3, B4, B5 were isolated in which three are gram positive (cocci form) and one is gram-negative (bacillus form). Only one strain shows (B4) the formation of endospore. The enzymatic activity of four isolates revealed that strains B3, B5 and both control1 (E. coli) and control 2(B. cereus) showed amylase activity whereas none of the strains showed protease and lipase activity. To test the susceptibility of isolated strains against chemotherapeutic agents, eight antimicrobial drugs were used to treat the susceptibility patterns of isolated bacteria. Among four isolates (B1, B3, B4, B5) strain B3 and control 2 (B. cereus) shows resistance to penicillin and rest of the strains were sensitive to all these antibiotics and also shows antagonistic activity against different human pathogens. The strains B1 and B3 shows moderate inhibition zone against Listeria monocytogenes ATCC 657, Klebsiella pneumonia MTCC5615 and Bacillus pumilis MTCC 1607 whereas strain B4 and B5 shows maximum zone of inhibition against Listeria monocytogenes ATCC657and Bacillus pumilis MTCC 1607.Therefore, intensive efforts must be initiated to identify and preserve all the indigenous breeds of cows for comparative chemical, microbiological and immunological analysis of milk, urine and dung with special reference to their agricultural, medicinal and nutritional significance.

p>Organic manures as a source of plant nutrients for the cultivation of field crops has received worldwide attention due to rising costs, rapid nutrient loss and adverse environmental impacts from inorganic fertilizers. A pot experiment was conducted in the net house of the Department of Agricultural Chemistry, BangladeshAgriculturalUniversity, Mymensingh to observe the effects of cow dung on growth, yield of stevia along with post-harvest fertility status of soil. Four treatments of CD viz. 0, 5, 7.5 and 10 t ha–1 in two contrasting soils (acid and non-calcareous) were examined following Completely Randomized Design (CRD) with three replications. Growth and yield attributes increased significantly with the advancement of growth period (60 DAP) and increased rate of CD up to 10 t ha–1. An overall performance of non-calcareous soil was better than acid soil. In non-calcareous soil, the leaf biomass yield was increased by 275% whereas in acid soil it was 268% over control. The acidity of both soils significantly decreased with the increased rate of CD. All essential plant nutrients viz. total N, available P exchangeable K, Ca, Mg, available S, Zn, B and organic matter content of soil were significantly increased with the increased levels of CD up to its highest dose (CD @ 10 t ha–1) in both soils. Thus from the findings of the present research work it can be concluded that for getting optimum leaf biomass yield of stevia along with fertility of both soils CD should be applied @ 10 t ha–1 J.

Cow dung is being used in agriculture as well for the household and religious purposes from the ancient time. Cow dung is known to possess antimicrobial activity and contains a wide variety of microorganisms with variable properties. Therefore, the present study was carried out to assess the microbial diversity including pathogenic ones of the cow dung samples as well as to determine the antimicrobial traits of the samples. In this regard, a total of 8 fresh cow dung samples were tested. All the samples contained a huge load of bacteria and fungi in an average of 108 and 107 cfu/g, respectively. An extended number of pathogenic bacteria were recovered. Among the pathogenic bacteria, Staphylococcus spp. and Bacillus spp. were predominantly found in every sample. The presence of Pseudomonas spp. Escherichia coli, Klebsiella spp. and fecal coliform were exhibited in most of the samples. Salmonella spp. and Vibrio spp. were found in 3 and 5 samples, respectively. The average load of the pathogens was 104 cfu/g. All the samples showed substantial degree of antimicrobial activity against all the pathogens tested. Samples 1, 2, 3 and 4 were effective in inhibiting the growth of all the tested pathogens. The findings of the present study revealed the need for safe application of cow dung in the agricultural field and of further investigation for the antimicrobial potential of the diversified microflora of cow dung offering agricultural, environmental and medical applications.
