Biodegradation of 2-mercaptobenzothiazolyl-(Z)-(2-aminothiazol-4-yl)-2-(tert-butoxycarbonyl) isopropoxyiminoacetate by Pseudomonas desmolyticum NCIM 2112

2-Mercaptobenzothiazolyl-(Z)-(2-aminothiazol-4-yl)-2-( tert -butoxycarbonyl) isopropoxyiminoacetate is used as supplementary additives in commercial-grade insecticides to compensate for the time factor needed for the actual pesticide chemical to start its action. This investigation describes the biodegradation of 2-mercaptobenzothiazolyl-(Z)-(2-aminothiazol-4-yl)-2-( tert -butoxycarbonyl) isopropoxyiminoacetate by Pseudomonas desmolyticum NCIM 2112. The biodegradation is influenced by other carbon and nitrogen sources and indicates that glucose and lactose are effective at 0.5% concentration whereas NaNO 3 and NaNO 2 at 0.05%. The percent degradation of 2-mercaptobenzothiazolyl-(Z)-(2-aminothiazol-4-yl)-2-( tert -butoxycarbonyl) isopropoxyiminoacetate was found to be 40%.The pH and temperature optima were found to be 7.0°C and 30°C, respectively. The effect on soil parameters was observed in treated soil and indicates remarkable decrease in soil fertility; the phytotoxicity indicates retarded growth and germination inhibition of treated seeds of Sorghum bicolor and Triticum aestivum . In paddy field the inhibition of germination of Oryza sativa was observed.
