Abstract

Chlorpyriphos (a broad-spectrum moderately toxic organophosphate insecticide) is widely used in the prevention of both agriculture pests and urban public health pests. It has large effects on the environment resulting from its long residual period in soil and water. During present study, survival and chlorpyriphos degrading capability of four bacterial isolates (SB1, SGB2, HIC2 and HIIGA2) was investigated in sterilized as well as unsterilized soil upto two months under laboratory conditions. Viable count of all isolates increased upto 45 days and decreased later on and it was higher in chlorpyriphos amended soil as compared to unamended soil at all stages of incubation. Viable count of inoculated bacterial isolates was higher in the sterilized soil as compared to unsterilized soil. Chlorpyriphos level decreased in inoculated as well as uninoculated treatments however, in the inoculated treatments at 60th  day of incubation, residual chlorpyriphos was less as compared to control both in sterilized as well as unsterilized soil. Percent utilization of chlorpyriphos was more in unsterilized soil as compared to sterilized soil. Maximum utilization of chlorpyriphos was observed with the isolate SB1 (66.0 %) followed by HIC2 (58.0 %), SGB2 (48.0%) and HIIGA2 (36.4 %) in sterilized soil and same trend was observed in unsterilized soil i.e. maximum utilization of chlorpyriphos with the isolate SB1 (79.2 %) followed by HIC2 (74.5 %), SGB 2 (60.4 %) and HIIGA2 (43.3 %) respectively.
