摘要：

The contamination of the environment with tetrabromobisphenol-A (TBBPA), an endocrine disruptor, is a concern. We examined anaerobic degradation of TBBPA in sediment samples from the Erren River in southern Taiwan. Anaerobic degradation of TBBPA was enhanced with the addition of humic acid (0.5 gL(-1)), sodium chloride (1 mass/vol%), zero-valent iron (1 g L-1), vitamin B-12 (0.025 mg L-1), brij 30 (55 mu M), brij 35 (91 mu M), rhamnolipid (130 mg L-1), or surfactin (43 mg L-1) but was inhibited by the addition of acetate (30 mM), lactate (20 mM), or pyruvate (20 mM). Sulfate-reducing bacteria, methanogen, and eubacteria are involved in the anaerobic degradation of TBBPA; sulfate-reducing bacteria is a major component of the sediment. (C) 2012 Elsevier B.V.
