Indiscriminate application of pesticides in paddy crop field soil to enhance paddy production could cause adverse impact on the both soil fertility and bacterial communities. The present study aimed to isolate bacteria prevalent in Lambdacyhalothrin exposed soil to determine their Lambdacyhalothrin degrading ability and assay the degraded metabolites. The observations registered in this study revealed that the dominant bacteria isolated from paddy crop field soil were Bacillus cereus and Aneurinibacillus migulanus. These bacteria were inoculated in soil spiked with Lambdacyhalothrin. After 36 hours of inocubation, the extract were analysed by GCMS. Lambdacyhalothrin degradation was accelerated by Aneurinibacillus migulanus (100 % of pesticide degraded compared to Bacillus cereus 94.09 % and control 55.2 % ). Thus Aneurinibacillus migulanus could be the used as bioagents to degrade lambdacyhalothrin.
