The organophosphorous pesticide, demeton-S-methyl was transformed by Corynebacterium glutamicum in co-metabolism with more readily degradable substrates. Glucose, acetate and fructose were tested as growth substrates, and the highest demeton-S-methyl biotransformation average rate (0.78 mg l(-1) h(-1)) and maximum instantaneous rate
Technical grade disulfoton (DiSyston) was fed to Beagle dogs (four animals per sex and treatment level) at nominal concentrations of 0, 0.5, 4 and 12 ppm for 1 year. The purpose of this study was to characterize the potential general

The reactions of thiometon and its ethyl analogue, disulfoton, with reduced sulfur species [e.g., bisulfide (HS-), polysulfide (S(n)2-), thiophenolate (PhS-), and thiosulfate (S2O3(2-))] were examined in well-defined aqueous solutions under anoxic conditions. The role of reduced sulfur species was investigated
Organophosphorus hydrolase (OPH, EC 8.1.3.1) is a dimeric, bacterial enzyme that detoxifies many organophosphorus neurotoxins by hydrolyzing a variety of phosphonate bonds. The histidinyl residues at amino acid positions 254 and 257 are located near the bimetallic active site present
