Degradation of bisphenol A by microorganisms immobilized on polyvinyl alcohol microspheres
Abstract In this study, microorganisms (named B111) were immobilized on polyvinyl alcohol microspheres prepared by the inverse suspension crosslinked method. The biodegradation of bisphenol A (BPA) and 4-hydro-xybenzaldehyde, a degradation product of BPA, by free and immobilized B111 was investigated. The BPA degradation studies were carried out at initial BPA concentrations ranging from 25 to 150 mg·L−1. The affinity constant Ks and maximum degradation rate R max were 98.3 mg·L−1 and 19.7 mg·mg−1VSS·d−1 for free B111, as well as 87.2 mg·L−1 and 21.1 mg·mg−1VSS·d−1 for immobilized B111, respectively. 16S rDNA gene sequence analyses confirmed that the dominant genera were Pseudomonas and Brevundimonas for BPA biodegradation in microorganisms B111.
