This study investigated the aerobic degradation ofbisphenol-A (BPA) and the derivatives bisphenol-B (BPB), bisphenol-F (BPF), tetrabromobisphenol-A (TBBPA), and tetrachlorobisphenol-A (TCBPA) in river sediment. The degradation rates of BPA and BPF were enhanced by adding brij 30, brij 35, rhamnolipid, surfactin, or crude enzyme; a higher degradation rate was observed with crude enzyme than with the other additives. The degradation rates of BPA and its derivatives (BPAs) in the sediment were BPF > BPA > BPB > TCBPA > TBBPA. Different BPAs affected the changes in the microbial community in the sediment. Sediment fractions with larger particle sizes demonstrated higher degradation rates. Different sediment particle sizes affected the changes in the microbial communities. Pseudomonas sp. may be the dominant bacteria in the process of degradation of BPAs in river sediment.
本研究考察了双酚 A（BPA）及其衍生物双酚 B（BPB）、双酚 F（BPF）、四溴双酚 A（TBBPA）和四氯双酚 A（TCBPA）在河底沉积物中的好氧降解。添加 Brij 30、Brij 35、鼠李糖脂、表面活性剂或粗酶可提高 BPA 和 BPF 的降解速率；与其他添加剂相比，粗酶具有更高的降解速率。BPA 和其衍生物（BPAs）在沉积物中的降解速率为 BPF > BPA > BPB > TCBPA > TBBPA。不同的 BPAs 影响沉积物中微生物群落的变化。粒径较大的沉积物组分具有更高的降解速率。不同的沉积物粒径影响微生物群落的变化。假单胞菌属可能是河底沉积物中 BPAs 降解过程中的优势菌。
