摘要： This study aimed at the biodegradation of fenpropathrin by Rhodopseudomonas sp. strain PSB07-21 cultured under different growth modes. The biomass production, cell surface hydrophobicity and fenpropathrin biodegradation efficiency of the strain PSB07-21 cultured under the photoheterotrophic growth mode were better than that shown by the strain PSB07-21 cultured under the photoautotrophic or the chemotrophic growth mode. Sodium dodecyl sulfate-polyacrylamidegelelectrophoresis analysis using cell-free protein extracts showed several distinct protein bands in the gels representing the strain PSB07-21 cultured under the photoheterotrophic growth mode. The fenpropathrin enzymatic degradation was clearly affected the bacterial growth mode. Results obtained from this study should improve our knowledge regarding fenpropathrin biodegradation under field conditions. Our findings can also be used to optimize the usage of Rhodopseudomonas sp. PSB07-21 in field applications.
