Calophyllum inophyllum (Calophyllaceae) has wide applications in traditional folk medicine. The methanol extract of C. inophyllum exhibited good antibacterial activities (17 ± 1.73 to 24 ± 1.15 mm) against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Klebsiella pneu-moniae, and Pseudomonas aeruginosa. The bioactive constituents of th...

Among several life-threatening diseases, vector-borne diseases play a significant role. Mosquito-borne conditions are dangerous and are more prevalent. Culex is the most prevalent and causative agent of many zoonotic diseases among various mosquito species. Endophytic fungi that reside in the healthy plant produce an array of bioactive compounds ag...

Endophytic fungi were isolated from forty plant leaf samples from Gudiyam forest. The potent antibacterial strain Aspergillus niger E12 isolated from the plant Dodonaea viscosa showed maximal antibacterial activity against all the test organisms, viz., Staphylococcus aureus, Bacillus coagulans, Escherichia coli, Klebsiella pneumoniae, and Pseudomon...

In the present study, the suitability of an invasive weed, Alternanthera ficoidea (L.) P. Beauv. (AF) biomass for vermicomposting has been tried by subjecting three different combinations of the weed and cow dung (CD) through 28 days pre-composting followed by 50 days vermicomposting with Eudrilus eugeniae. The maximum temperature recorded in P1 (1...

Vermicomposting of paper mill sludge (PMS) with cowdung (CD) and green manure plants, Tephrosia purpurea (TEP) and Gliricidia sepium (GLS) in different combinations (21 days pre-decomposed) was carried out using Eisenia fetida (60 days). Results revealed that electrical conductivity, total Kjeldahl nitrogen, total phosphorus, total potassium and NN...

The in vitro anticancer activity of ethanolic fruit extracts of Capparis sepiaria (Capparaceae), Commiphora berryi (Burseraceae), Hugonia mystax (Linaceae) and Morinda umbellata (Rubiaceae) were tested using different cancer cell lines, HeLa (human, epithelial cervical cancer), MCF-7 (human, breast cancer), DLA (ascetic tumour) and L-6 (normal rat...

Andrographis is an important genus of the family Acanthaceae known for its ethnomedicinal claims and for a variety of medicinal properties. The current review briefly summarizes the distribution, phytochemical components, biological and pharmacological activities of Andrographis spp. distributed in Southern Eastern Ghats, South India along with col...

A b s t r a c t: Antitumor and antioxidant activities of methanolic extracts of leaf and stem bark of Hugonia mystax L. against Dalton s Lymphoma Ascites (DLA) bearing female Swiss albino mice was carried out. The effect of leaf and stem bark extracts of H. mystax on tumor growth and host s survival time was studied by the following parameters: ave...

Introduction Giant freshwater prawn (Macrobrachium rosenbergii (de Man, 1879) (or scampi) is an important commercial species due to property as food supply as well as a valuable export product. In India, giant freshwater prawn distributes mainly in the Southern region where environmental conditions are most favorable for the ISSN: 2347-3215 Volume...

The comparative effect of bacterial biofertilizers such as Rhizobium, Phosphobacteria and Azozpirillum on growth and yield of green gram (Phaseolus radiata L.) and cowpea (Vigna siensis Edhl.) was studied. The bacteria were isolated from the soil samples and identified by staining and biochemical tests. The seeds were inoculated with bacterial biof...

A total of 100 clinical samples were collected from different hospitals and microbiology laboratories in Kancheepuram district, Tamilnadu, India that includes Blood (15 samples), Pus swabs (25 samples), Stool (40), Urine (20 samples) for screening the E. faecalis. Among the 100 clinical samples 47 isolates showed Enterococcus faecalis. The bacteria...

A total of 30 samples were collected Kancheepuram district, Tamilnadu that includes citrus fruit, leaves and stem for screening the plant pathogenic bacteria with reference to X.campestris. The bacterial isolates from the samples for the present study were confirmed as X.campestris. Among the 30 plant samples 20 isolates showed Positive for X.campe...

Petroleum forms a major source of raw material for many chemical products such as plastics, paints and cosmetics. It is also a source of energy for Industry and daily life. When it is transported oil spills occur leading to oil pollution which causes serious problem in marine and soil environment. So Biodegradation plays a vital role in removing oi...

The people of Saudiarabia are often suffering from food poisoning and other health diseases. The isolation of pathogens from domestic refrigerators was performed to determine the prevalence of pathogenic microorganisms. Samples (n = 150) were obtained from domestic refrigerators of various parts of Jeddah, Saudiarabia. In these samples, Staphylococ...

Pre-decomposed (15 days) mango leaf litter with cowdung in 50:50 (wt/wt) was subjected to vermicomposting using Perionyx ceylanensis for 60 days. The electrical conductivity, total NPK, Ca, Na and other nutrients were higher in the vermicompost than in the worm unworked control substrate, whereas organic carbon and C/N ratio were lowered. The popul...

Sugar industry-derived pressmud was mixed with an equal amount of cow dung (1:1), and vermicomposted with Perionyx ceylanensis Mich.
