| 520 | 3 | |a Continuous use of the pyrethroid insecticide beta-cypermethrin (beta-cp) has resulted in serious environmental contamination problems. We report here that a novel bacterial strain BSF01, which was isolated from activated sludge and identified as Bacillus subtilis (collection number: CCTCC AB 2014103), showed high efficiency in degrading beta-cp. Strain BSF01 was able to utilize beta-cp as the sole carbon source for growth and degraded 89.4% of 50mgL−1 beta-cp within 7days. The optimal conditions for beta-cp degradation were determined to be 34.5°C, pH 6.7, and inocula amount 0.11g dry wtL−1 using response surface methodology. The kinetic parameters q max, K s, and K i were established to be 2.19day−1, 76.37mgL−1, and 54.14mgL−1, respectively. The critical inhibitor concentration was determined to be 64.30mgL−1. Seven metabolites were identified by gas chromatography-mass spectrometry. Furthermore, a novel biodegradation pathway for beta-cp was proposed on the basis of analysis of the metabolites. This strain was also capable of degrading a wide range of pyrethroid insecticides including cypermethrin, deltamethrin, cyhalothrin, and beta-cyfluthrin, which similar to beta-cp are hazardous chemicals. Taken together, our results depict the biodegradation pathway of beta-cp and highlight the promising potentials of strain BSF01 in bioremediation of pyrethroid-contaminated environments. | |
