Web2. Cypermethrin: The petroleum ether phase was concentrated and cleaned up by liquid solid chromatography on a Florisil column. The eluate was analysed for Cypermethrin content using GC-EC (McKee et al., (1981). The limits of determination (LOQ) for Cypermethrin were claimed (no data) as 10 m g/kg and 50-100 m g/kg for 3PBA. … WebGC-MS analysis of biodegraded cypermethrin showed the presence of 4-propylbenzoate, 4-propylbenzaldehyde, phenol M-tert-butyl and 1-dodecanol, etc. which was not reported earlier in cypermethrin metabolism; hence a novel biodegradation pathway of cypermethrin with Bacillus sp. strain SG2 is proposed in this study.
