Residues of Dimethoate present in locally available Spinach varities Palak : Beta maritima, Vendhai : Trigonella foenumgraecum, Thandan : Amarnathus mangostanus green and red were determined. The quantification was carried out using RP-HPLC for unprocessed (fresh) and processed (washed, washed and cooked) Spinach samples. The extraction was carried out with benzene. It was found that unprocesse...

Biopesticides serve as second-hand biocontrol agents against harmful microbial growth and supplement organic pesticides in several agricultural systems. In the production of alternative controls for synthetic insecticides to kill insect pests, biotechnology may also condone them. Bacterial fungal such Ampelomyces quisqualis Trichoderma spp., (a control agent grape powdery mildew) Bacillus subti...

Bacteria exhibit the ability to metabolize a wide array of contaminants and, as a result, reduce their toxicity to wildlife and humans. The general goal of this project was to design and evaluate, as a proof-of concept, a DNA microarray assay to evaluate bacterial detoxification mechanisms in contaminated sediments. The assay consists of 100 probes that measure activity of bacterial remediation...

some wastes especially wastes of food industries need to be treated in order to recover some value-added products. one of these valuable products is biological pesticides. today, the most successful biological pesticides are produced by gram-positive, rod-shape bacteria, the genus bacillus that produces crystalline endotoxin proteins during spore formation. these toxins will be activated when t...

Risk assessments for pesticides typically focus on the compound itself ignoring impact of its transformation byproducts. Challenges in isolating such byproducts (i.e. after application pesticide soil) often lead to underestimation real risk from substances. The toxicological properties these may differ those parent pesticides; hence, special attention is required new emerging contaminants. In t...
