ABSTRACT
A 17ß-estradiol (E2) degrading strain (designated as Wu-SP1) was isolated from the activated sludge collected from a wastewater treatment plant (WWTP) in Xi'an. The strain was identified as Fusarium sp. according to 18S rDNA sequence and phylogenetic analysis. The optimal pH and temperature for E2 degradation were 6 and 30â, respectively. Under these conditions, the E2 biodegradation rate of 2 mg·L-1 E2 amounted to 92.5% within 48 h by this strain. The kinetics of E2 degradation by the strain KY123915 were in good accord with the first-order equation, with the concentration ranged from 10 to 500 mg·L-1. UV spectrum analysis showed the strength of maximum absorption of metabolites became weak compared to E2, indicating that E2 may be degraded via estrone (E1) by Fusarium sp. KY123915.
