Article
Copper oxide nanoparticles (CuO·NPs) biosynthesized from plant extracts is emerging nanotechnology for medical and environmental applications. In the current study, the leaf extract of a medicinal plant, Abrus precatorius was used as a reducing agent for CuO·NPs biosynthesis and the formation of NPs was confirmed with various techniques. CuO·NPs (0...
Article
In our current work, we have focused on AgNPs biosynthesis from the ethanolic leaf extract of Tinospora cordifolia and evaluated for their antioxidant, hepato and nephro-protective effects. The results depicted significant restoration in the serum levels of urea, creatine, and uric acid, SGOT and SGPT in potassium bromate induced Swiss albino mice...

In this study agro-waste (Agwt) was aerobically composted using cow dung (CD) and mule dung (MD). Totally six different sets of compost treatments were prepared, as T1 (Agwt + CD, 1:1), T2 (Agwt + MD, 1:1), T3 (Agwt + CD, 1:3), T4 (Agwt + MD, 1:3), T5 (Agwt + CD, 3:1) and T6 (Agwt + MD, 3:1) in individual containers. All the compost treatments were...

Purpose Recovering the nutrients from organic solid residues is an ever demanding approach in terms of eco-friendly management. In this study, the efficiency of the earthworms, Perionyx ceylanensis and Perionyx excavatus in recycling and recovering plant nutrients from urban and agricultural biomass residues was investigated. Methods Vermicomposti...

Pesticides have become an inseparable part of modern agricultural production and technology. Malathion pesticide more than 139,000 MT production capacity annually, with more than 219 technical grade and manufacturing units, and over 4000 formulation units in India. The earthworm survey was carried out in all the five sites at regular monthly interv...

In the present study, green synthesized zinc sulfide nanoparticles (ZnS NPs) from the leaves of the medicinal plant, Abrus precatorius, were characterized and tested for toxicity using Eudrilus eugeniae. The formation of ZnS NPs through green synthesis was confirmed by using UV-Vis spectroscopy, FE-SEM, FT-IR, and XRD analyses. The clitellate earth...

Microbial decolourization of textile dyes is cost effective and eco-friendly method. Two bacterial species (Bacillus cereus and Bacillus flexus) and one fungal species Aspergillus niger were isolated from the dye spilled soil and identified through biochemical and molecular characterization by gene sequencing. Phylogenetic tree was constructed with...
Article
Seaweed (T1), sugarcane trash (T2), coir pith (T3) and vegetable waste (T4) with cowdung (1:1, w/w) were vermicomposted using Eudrilus eugeniae (50 days). The pH in vermicomposts showed a decrease while electrical conductivity showed increment. The organic matter content, organic carbon, lignin, cellulose, C/N and C/P ratios in vermicompost was sig...
Article
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...
Article
Fifteen days pre-decomposed seaweeds, Halimeda gracilis, Gracilaria corticata, Sargassum wightii and Sargassum swartzii spiked with cowdung (1:1) were vermicomposted using Perionyx excavatus for 60 days. The pH in the vermicompost showed insignificant reduction while electrical conductivity showed significant enhancement (P < 0.05). The reduction o...
Article
The seaweeds, Gracilaria edulis, Turbinaria ornata and Ulva reticulata collected from Mandapam East Coast region of Tamil Nadu, India has been subjected to vermicomposting in combination with cowdung (CD) in 1:1 combination for 60 days under laboratory conditions. The percentage decomposition was ranged between 83.70 and 87.00 in the vermicompost o...

The aim of this study was to investigate the biochemical responses in three earthworm species, Eudrilus eugeniae, Perionyx ceylanensis and Perionyx excavatus induced by exposure to pesticide (carbaryl) and metal (lead) in soil. Earthworms were exposed to increasing concentrations of carbaryl (12, 25 and 50 mg kg −1) and Pb (75, 150 and 300 mg kg −1...

The coelomic fluid protein profiling studies were performed under pesticide and metal stress condition in three species of earthworms namely Eudrilus eugeniae, Perionyx excavatus and Perionyx ceylanensis. The carbaryl (12, 25 and 50 mg/kg) and lead (70, 150 and 300 mg/kg) were used as an agent to measure the changes in the coelomic fluid profile. T...
Article
In this study, we report the biosynthesis of silver nanoparticles using the ethanolic leaf powder extract of Premna serratifolia L. and its anticancer activity in carbon tetra chloride (CCl 4)-induced liver cancer in Swiss albino mice (Balb/c). The synthesized silver nanoparticles were characterized by SEM, FTIR and XRD analyses. The Debye–Scherrer...
Article
Earthworm gut microbial isolates as inoculants for composting (windrow method) of pressmud along with the application of spent wash as a primary source of moisture has been studied. The changes physicochemical changes accompanying the composting process of pressmud were observed. Composting cycle took nine weeks, during the process every 15 days, p...
Article
Municipal solid waste (MSW) was vermicomposted in combination with cowdung (CD) using Perionyx ceylanensis for 50 days. The decomposition rate of 55-78% was observed in different vermibed substrates, the highest being CD followed by 10:1 ratio of CD+MSW. The C/N ratio was reduced from 41.8 to 17.6 and 38.8 to 15.4 in MSW+CD (10:1) and CD, respectiv...
