It has been included in the initial Water Watch List. The aim of this study was to isolate bacteria from consortia recovered from mine sediments and acid mine drainage samples, both considered extreme environments, with the ability to degrade EE2. From the most promising consortia, isolates affiliated with the Aeromonas, Rhizobium, and Paraburkholderia genera were obtained, demonstrating the capability of growing at 50 mg\/L EE2. Subsequently, these isolates were tested with 9 mg\/L of EE2 as the sole carbon source. Among the isolated strains, Aeromonas salmonicida MLN-TP7 exhibited the best performance, efficiently degrading EE2 (95 \u00b1 8%) and reaching concentrations of this compound below the limits of detection within 7 and 9 days. The final metabolites obtained are in accordance with those of the TCA cycle; this may indicate EE2 mineralization. As far as is known, Aeromonas salmonicida was isolated for the first time and identified in acid mine drainage, demonstrating its capacity to degrade EE2, making it a promising candidate for bioaugmentation and suggesting its possible applicability in low pH environments.<\/jats:p>","DOI":"10.3390\/cleantechnol6010008","type":"journal-article","created":{"date-parts":[[2024,2,1]],"date-time":"2024-02-01T09:43:22Z","timestamp":1706780602000},"page":"116-139","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Biodegradation of 17\u03b1-Ethinylestradiol by Strains of Aeromonas Genus Isolated from Acid Mine Drainage"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8614-570X","authenticated-orcid":false,"given":"T\u00e2nia Luz","family":"Palma","sequence":"first","affiliation":[{"name":"Centre of Marine Sciences (CCMAR\/CIMAR LA), Campus de Gambelas, University of Algarve, 8005-139 Faro, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Clara","family":"Costa","sequence":"additional","affiliation":[{"name":"Centre of Marine Sciences (CCMAR\/CIMAR LA), Campus de Gambelas, University of Algarve, 8005-139 Faro, Portugal"},{"name":"Faculdade de Ci\u00eancias e Tecnologias, Campus de Gambelas, University of Algarve, Building 8, 8005-139 Faro, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Rosenfeld, P.E., and Feng, L.G.H.
