title: Dimerization of bisphenol A by hyper lignin-degrading fungus Phanerochaete sordida YK-624 under ligninolytic condition.
abstract: Bisphenol A (BPA) was treated with hyper lignin-degrading fungus Phanerochaete sordida YK-624 under ligninolytic condition. After preculturing P. sordida YK-624 for 4 days, BPA (final concentration, 1 and 0.1 mM) was added to cultures. Both 1- and 0.1-mM BPA were effectively decreased within a 24-h treatment and two metabolites were detected. Two metabolites (5,5'-bis-[1-(4-hydroxy-phenyl)1-methyl-ethyl]-biphenyl-2,2'-diol and 4-(2-(4-hydroxy-phenyl) propan-2-yl)-2-(4-(2-(4-hydroxyphenyl) propan-2-yl) phenoxy)phenol) were identified by ESI-MS and NMR analysis. These results indicated that BPA was oxidized to BPA phenoxy radicals by ligninolytic enzymes and then dimerized at extracellular region.
