The possibility of removing bisphenol A and its five potential substitutes (bisphenols S, F, AF, E, and B) was tested using microorganism consortia from river water and activated sludge from municipal and rural wastewater treatment plants. For most bisphenols, biodegradation with activated sludge was faster than with river water and a greater extent of biodegradation was also achieved. However, only bisphenol A and bisphenol F underwent 100% primary biodegradation while other bisphenols degraded no more than about 50% which has some important implications in case of their increased usage. Metabolic activity in biodegradation liquors was also tested and it showed higher activity in the tests with activated sludge than with river water. However, there was no clear connection between the decline of metabolic activity and the extent of biodegradation as decreased activity was observed for two easily degrading bisphenols and two others with little biodegradability. It can be assumed that two different phenomena are involved in this process including depletion of nutrients for easily degradable bisphenol A and absence of nutrients for bacteria incapable of primary degradation of bisphenol AF and bisphenol S.

使用微生物联合体从河水中以及市政和农村污水处理厂的活性污泥测试了去除双酚A及其五种潜在替代物（双酚S，F，AF，E和B）的可能性。对于大多数双酚，活性污泥的生物降解速度比河水更快，并且还实现了更大程度的生物降解。但是，只有双酚A和双酚F经历了100％的一次生物降解，而其他双酚的降解不超过约50％，这在其使用量增加的情况下具有重要意义。还对生物降解液中的代谢活性进行了测试，在活性污泥测试中其活性比河水更高。然而，代谢活性的下降与生物降解程度之间没有明确的联系，因为观察到两种易降解的双酚和另外两种生物降解性差的活性降低。可以假定此过程涉及两种不同的现象，包括易降解双酚A的养分消耗和无法使双酚AF和双酚S初步降解的细菌缺乏养分。
