Prevalence of pesticide degrading bacteria in Paddy crop field

[摘要] The application of pesticides in paddy crop field soil to enhance paddy production could cause adverse impact on the soil bacteria. Hence, the present study aimed to isolate bacteria prevalent in pesticide (Profenofos and Lambdacyhalothrin) exposed soil and also to determine whether the pesticide resistance and degradation trait exhibited by bacteria were plasmid or chromosomal mediated. The dominant bacteria isolated from paddy crop field soil Bacillus cereus and Aneurinibacillus migulanus were plasmid cured and exposed to Profenofos and Lambdacyhalothrin. The observations registered in this study revealed that Profenofos resistant and degradation trait of Bacillus cereus and Aneurinibacillus migulanus were plasmid mediated, whereas, Lambdacyhalothrin resistant and degradation trait of Bacillus cereus and Aneurinibacillus migulanus were chromosomal mediated.
