Pesticides belonging to pyrethroid group are widely used in agricultural fields check pest infestation different crops for enhanced food production. In spite of beneficial effects, non-judicious use pesticides imposes harmful effect on human health as their residues reach materials and ground water via leaching, percolation bioaccumulation. Looking into the potential microbial degradation toxic compounds under natural environment, a cypermethrin-degrading Bacillus sp. was isolated from pesticide-contaminated soil rice field Distt. Udham Singh Nagar, Uttarakhand, India. The bacteria degraded compound up 81.6 % within 15 days standard growth conditions (temperature 32 °C pH 7 shaking at 116 rpm) minimal medium. Analysis intermediate biodegraded cypermethrin revealed that opted new pathway degradation. GC–MS analysis showed presence 4-propylbenzoate, 4-propylbenzaldehyde, phenol M-tert-butyl 1-dodecanol, etc. which not reported earlier metabolism; hence novel biodegradation with strain SG2 is proposed this study.
