Estrogenic activities of BPA treated with T. versicolor and laccase

Conditions	Control	BPA (25 mg/L)	BPA (25 mg/L) + laccase (25 U/L)b	BPA (25 mg/kg substrate) + T. versicolor c
PEa	1	5.37 ± 0.18	1.39 ± 0.12	1.36 ± 0.15

^aPE (proliferative efficiency) is the ratio between the cell number in the presence and in the absence of samples (control)

^bThe reaction time of BPA degraded by laccase was 24 h

^cThe culture time of BPA degraded by T. versicolor was 10 days
