摘要

A bacterial strain capable of degrading carbofuran as the sole carbon source was isolated from carbofuran-phytoremediated rhizosphere soil of rice. A 16S rRNA study identified the strain as Burkholderia sp. (isolate PCL3). Free cells of isolate PCL3 possessed inhibitory-type degradation kinetics with a q max of 0.087 day−1 and S m of 248.76 mg·L−1. Immobilised PCL3 on corncob and sugarcane bagasse possessed Monod-type degradation kinetics with a q max of 0.124 and 0.098 day−1, respectively. The optimal pH and temperature with the highest degradation rate coefficient of carbofuran were pH 7.5 and 35 °C, respectively.View full textDownload full textKeywordsbiodegradation, carbofuran, kinetics, Burkholderia sp.
