Effective simultaneous removal of 17β-estradiol and tetracycline by a novel Alkalibacterium strain: characteristics, mechanisms, and application in livestock wastewater treatment.

ABSTRACT: The environmental risk posed by 17β-estradiol (E2) and tetracycline (TC) contamination within livestock wastewater has been widely concerned. Especially, the co-occurrence of these pollutants poses a tremendous challenge to their efficient bioremediation, highlighting the need for strains capable of simultaneous E2 and TC removal. In this study, a novel strain of Alkalibacterium sp. AEPI-S25 was successfully isolated from the sediments of Qinghai Lake, demonstrating the ability to remove 89.91% of 20 mg L^-1 E2 and nearly 100% of 20 mg L^-1 TC simultaneously within 5 days. AEPI-S25 exhibited remarkable environmental adaptability and maintained high simultaneous removal efficiency under various stress conditions and the presence of two typical livestock wastewater sample
