Isolation and characterization of a new highly effective 17β-estradiol-degrading Gordonia sp. strain R9.

ABSTRACT: In this report, Gordonia sp. strain R9 isolated from an enrichment culture of chicken leachate was confirmed to degrade 17β-estradiol (E2), which can also use other estrogens (estrone, estriol, and 17α-ethynylestradiol) and testosterone as sole carbon and energy sources. Optimization of growth conditions showed that Gordonia sp. strain R9 can tolerate a very wide range of temperature (4-40 °C) and pH (1.0-11.0), and is sensitive to antibiotics including kanamycin, ampicillin, chloramphenicol, and carbenicillin. Optimal culture conditions for E2 degradation were 30 °C and pH 7.0 with almost 100% degradation of E2 concentrations ranging from 50 µg/L to 5 mg/L within 24 h. The E2 intermediates so generated included estrone (E1), estratriol (E3), (3Z)-3-(3-hydroxy-3a-methyl-7-oxo
