Biodegradation and detoxification of bisphenol A with one newly-isolated strain Bacillus sp. GZB: Kinetics, mechanism and estrogenic transition

► A facultative anaerobic bacterium, Bacillus sp. GZB was isolated and characterized. ► Biodegradation and mineralization were investigated in detail. ► Metabolites of BPA were identified and doubly confirmed by authentic standards. ► Two standards were synthesized and three initial intermediates were quantified. ► Estrogenic activity transition during BPA aerobic degradation was investigated.
