چکیده انگلیسی
The feasibility of 17β-estradiol (E2) and 17α-ethynylestradiol (EE2) removal by Trametes versicolor was demonstrated in batch and continuous cultures. In batch, E2 and EE2 initially supplied at 10 mg lâ1 were removed by more than 97% in 24 h, which corresponded to volumetric removal rates of 0.43 and 0.44 mg lâ1 hâ1, respectively. A bioreactor inoculated with T. versicolor pellets was then continuously operated during 26 days at a hydraulic retention time of 120 h. E2 and EE2 were completely removed at volumetric removal rates of 0.16 and 0.09 mg lâ1 hâ1, respectively, when fed at 18.8 and 7.3 mg lâ1, respectively. Evidence was found that removal was caused by laccase. This study demonstrates the technical feasibility of fungal treatment of estrogens using continuous bioreactor with suspended fungal biomass.
