Screening And Characterization Of Triazophos Tolerant Bacteria From Soil

Triazophos (Hostathion 40% EC) an organophosphate is widely used pesticide to combat insect pests on various crops of vegetables and cotton. Its overuse has led to the contamination of environment which is of great concern. In the present study efforts were being made to isolate, screen and characterize bacterial strains which could tolerate triazophos at higher doses and utilize it as sole carbon source. Two bacterial isolates out of forty tolerated Hostathion 40% EC. These two bacterial isolates were characterized morphologically, biochemically and identified using 16S rRNA sequencing technique as Staphylococcus lentus and Lysinibacillus fusiformis. These two strains were reported to tolerate triazophos as sole carbon source suggesting their utilization further in bioremediation process.
