The biologic degradation of 2,2-bis(4-hydroxyphenyl)propane (bisphenol A [BPA];1) was studied with 26 fungi. An initial BPA concentration of 40 ppm in an aqueous solution was degraded in the dark for 14 d. Among the 26 strains tested, 11 degraded BPA at 50% or more. Furthermore, four strains (F. sporotrichoides NFRI-1012, F. moniliforme 2-2, A. terreus MT-13, and E. nidulans MT-98) were more effective for degradation of BPA.
