Pseudomonas aeruginosa CH7, isolated from activated sludge, was able not only to isomerize and degrade beta-cypermethrin but also to utilize it as the sole source of carbon and energy for growth and produce biosurfactant. The strain effectively degraded beta-cypermethrin with inocula biomass of 0.1-0.2 g L(-1) at 25-35°C, pH 6-9, and a final concentration of beta-cypermethrin 25-900 mg L(-1). Via response surface methodology analysis, we found the optimal condition was 29.4°C, pH 7.0, and… CONTINUE READING
