After ethanol acclimation, a strain of SRB that could reduce chromium (CR-1) was selected as the research object. The optimum growth conditions for hexavalent chromium removal by the strain were determined by single-factor analysis. The chromium removal mechanism of the strain was analyzed, and a kinetic model of the reduction process was established. The chromium-reducing ability of the strain was 500 mg\/L, the optimum pH value was 7, the optimum temperature was 35 \u00b0C, the optimum cultivation time was 24 h, and the optimum ratio of bacteria to waste (volume ratio of bacterial solution dosage and chromium-containing wastewater) was 1:5. The mechanism of treatment of Cr(VI) by this strain is mainly based on the reduction of Cr(VI) by H2S accumulated in the cultured bacterial solution and the small amount of H2S generated by bacterial reductase, bacterial growth and SO42\u2212 reduction in the waste liquid.<\/jats:p>","DOI":"10.2166\/wst.2020.057","type":"journal-article","created":{"date-parts":[[2020,2,12]],"date-time":"2020-02-12T11:06:52Z","timestamp":1581505612000},"page":"2362-2372","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":16,"title":["Treatment of high-concentration chromium-containing wastewater by sulfate-reducing bacteria acclimated with ethanol"],"prefix":"10.2166","volume":"80","author":[{"given":"Xilin","family":"Li","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Liaoning Technical University, No. 88 Yulong Road, Xihe District, Fuxin, Liaoning Province 123000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Fan","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Liaoning Technical University, No. 88 Yulong Road, Xihe District, Fuxin, Liaoning Province 123000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Liu","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Liaoning Technical University, No. 88 Yulong Road, Xihe District, Fuxin, Liaoning Province 123000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinghua","family":"Chang","sequence":"first","affiliation":[{"name":"School of Science, Liaoning Technical University, 47 Zhonghua Road, Xihe District, Fuxin, Liaoning Province 123000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiawen","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Liaoning Technical University, No. 88 Yulong Road, Xihe District, Fuxin, Liaoning Province 123000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2020,2,12]]},"reference":[{"key":"key-10.2166\/wst.2020.057-1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtice.2014.11.026"},{"key":"key-10.2166\/wst.2020.057-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jenvman.2018.12.048"},{"key":"key-10.2166\/wst.2020.057-3","doi-asserted-by":"publisher","DOI":"10.1007\/s11356-013-1728-4"},{"key":"key-10.2166\/wst.2020.057-4","doi-asserted-by":"publisher","DOI":"10.2166\/wst.2019.060"},{"key":"key-10.2166\/wst.2020.057-5","volume-title":"Berger Bacterial Identification Manual","author":"Buchanan","year":"1984"},{"key":"key-10.2166\/wst.2020.057-6","first-page":"102","article-title":"Experimental study on microbial treatment of alkaline wastewater containing chromium (Cr(VI))","volume":"5","author":"Chai","year":"2005","journal-title":"Journal of Central South University (Natural Science Edition)"},{"key":"key-10.2166\/wst.2020.057-7","unstructured":"Chen T. 2006 Isolation and Purification of Sulafte-Reducing Baeterium and Study on Chermium Reduction.
