A native bacterial consortium degrades estriol in domestic sewage and activated sludge via the 4,5-seco pathway and requires estriol to retain its biodegradation phenotype.

Abstract excerpt

Estriol (E3) is one of the natural steroid estrogens commonly detected in wastewater. Although microbial biodegradation is a key process for removal of steroid estrogens during wastewater treatment, estriol biodegradation, and biotransformation mechanisms, as well as the involved bacterial consortia remain to be revealed. We enriched three E3-degrading bacterial consortia from raw sewage (inflow wastewater) and...
