Abstract 17 β‐Estradiol is produced by animals, and humans excreted through excreta, has endocrine‐disrupting activity. Bacterial degradation one of the suitable methods used for removal β‐estradiol (E2) from natural environment. In this study, E2‐degrading bacteria were screened enriched sediment sample wastewater Two bacterial strains ( Stenotrophomonas maltophilia MN08 Pseudomonas aeruginosa KL10) determined >70% E2‐degradation was achieved. The strain could rapidly remove approximately 86.5% ± 1.3% E2 within 7 days treatment. addition, KL10 removed 79.5% 1% same period. Optimized culture temperature pH medium improve E2‐degradation. results demonstrated that exhibited maximum activity at 35°C, 8.0. optimal to degrade ranged 7.0 9.0. level mixture systems can exhibit synergistic individual 87.3% 1.2% 81.4% 1.5%, respectively. potential mixed system 91.3% 2.9% under optimized conditions in which 100 mg/L served as sole source carbon energy. present finding demonstrates co‐culture S. P. may provide a promising bio‐treatment strategy steroids wastewater.
