Abstract	In the present study, sediment was spiked with bisphenol A (BPA) solution to explore the interaction between indigenous bacterial communities and BPA biodegradation in sediment. Results showed that BPA could be adsorbed to the sediment and then biodegraded rapidly. Biodegradation efficiency of BPA in treatments with 10 and 50 mg/L BPA reached 64.3 and 61.8% on the first day, respectively. Quantitative polymerase chain reaction and denaturing gradient gel electrophoresis analysis indicated that BPA affected the densities, species, and diversities of bacteria significantly. The response of bacterial community to BPA favored BPA biodegradation by promoting the growth of BPA-reducing bacteria and inhibiting other competitors. According to the results of sequencing, Pseudomonas and Sphingomonas played vital roles in the degradation of BPA. They presented over 73% of the original bacterial community, and both of them were promoted by BPA comparing with controls. Laccase and polyphenol oxidase contributed to the degradation of BPA and metabolic intermediates, respectively. This paper illustrates the rapid biodegradation of BPA induced by the response of indigenous bacterial communities to the BPA stress, which will improve the understandings of BPA degradation in sediment.
