Isolation and Characterization of Aerobic and Facultative Anaerobic 17β-Estradiol Degrading Bacteria in Paddy Soils and Their Potential Mechanisms

Toxics, Journal Year: 2025, Volume and Issue: 13(4), P. 292 - 292

17β-estradiol (E2) contamination resulting from the widespread use of animal manure poses a new threat to agricultural environment. Since anaerobic environments have been reported significantly extend persistence E2, estrogen pollution farmland soils (e.g., paddy soils) is particular concern, necessitating development in situ high-efficiency E2 bioremediation microorganisms. In this work, six E2-degrading strains were isolated soils, including Elizabethkingia, Stenotrophomonas, Microbacterium, Ochrobactrum, Gordonia, and Acinetobacter. Among these strains, Ochrobactrum sp. AEPI-SP11 Acinetobacter AEPI-SP17 able degrade over 90% 20 mg/L within 5 days. Although both exhibited strong tolerance pH, temperature, initial concentrations (2, 5, 20, 50 mg/L), only was capable biodegrading under conditions. Based on genomic analysis, we further obtained whole genome sequences identified compared potential genes responsible for degradation two strains. Overall, work enhances our understanding offers valuable insights into mechanisms varying conditions, provides microbial resources effective control farmlands.

Removal of Emerging Contaminants (Endocrine Disruptors) Using a Photocatalyst and Detection by High-Performance Liquid Chromatography (HPLC)

International Journal of Environmental Research and Public Health, Journal Year: 2025, Volume and Issue: 22(3), P. 334 - 334

Published: Feb. 24, 2025

Among several types of emerging contaminants, the endocrine disruptors 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) are particularly notable. These compounds discharged into sewage systems subsequently water bodies, as conventional wastewater treatment processes unable to effectively eliminate such pollutants. Therefore, present study aimed evaluate possibility removing from using photocatalytic activity compound Ag3AsO4. Silver arsenate was synthesized characterized, quantification hormones E2 EE2 achieved by high-performance liquid chromatography with a fluorescence detector, validation process some preliminary tests were performed on photodegradation Ag3AsO4 catalyst. Validation performed, satisfactory results achieved: r = 0.9987 (E2), 0.9984 (EE2), detection limit 5.01 0.51 15.19 1.54 coefficients variation for precision intraday interday lower than 10.9725% 11.3393%, respectively, recovery 100.15% 100.31% (EE2). In studies, showed different behavior in presence light each hormone. solution E2, it reached removal rate 35% hormone under LED light, acting photocatalyst, while EE2, 96%; both obtained after 30 min exposure visible light. When this is compared other materials, high efficiency photocatalyst persistent becomes evident. This advancement has significant implications treatment, offering promising that can mitigate environmental impacts caused disruptors.
