Strain C2 was identified as Ochrobactrum sp. on the basis of 16S rDNA sequence analysis According to 16S rDNA gene sequence analysis, Strain C2 was identified as Ochrobactrum sp. Strain C2 could utilize quinoline as the sole carbon sources and nitrogen sources to grow and degrade quinoline well under acidic conditions. The optimum inoculum concentration, temperature and shaking speed for quinoline degradation were 10%, 30 \u00b0C and 150 r\/min, respectively. The degradation of quinoline at low concentration by the strain followed the first-order kinetic model. The growth process of strain C2 was more consistent with the Haldane model than the Monod model, and the kinetic parameters were: Vmax = 0.08 h\u22121, Ks = 131.5 mg\/L, Ki = 183.1 mg\/L. Compared with suspended strains, strain C2 immobilized by sodium alginate had better degradation efficiency of quinoline and COD. The metabolic pathway of quinoline by Strain C2 was tentatively proposed, quinoline was firstly converted into 2(1H) quinolone, then the benzene ring was opened with the action of catechol 1,2-dioxygenase and subsequently transformed into benzaldehyde, 2-pentanone, hydroxyphenyl propionic acid and others.<\/jats:p>","DOI":"10.2166\/wst.2022.249","type":"journal-article","created":{"date-parts":[[2022,8,10]],"date-time":"2022-08-10T10:34:35Z","timestamp":1660127675000},"page":"1284-1298","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":7,"title":["Biodegradation characteristics and mechanism of quinoline by <i>Ochrobactrum<\/i> sp. strain C2"],"prefix":"10.2166","volume":"86","author":[{"given":"Qiancheng","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Chemical and Environmental Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiaoyu","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Chemical and Environmental Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziliang","family":"Qiu","sequence":"additional","affiliation":[{"name":"School of Chemical and Environmental Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caihong","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Chemical and Environmental Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2022,8,10]]},"reference":[{"issue":"3","key":"2022091514111089400_WST-EM211498C1","doi-asserted-by":"crossref","first-page":"335","DOI":"10.1007\/s10532-009-9304-9","article-title":"Quinoline biodegradation and its nitrogen transformation pathway by a Pseudomonas sp. strain","volume":"21","year":"2010","journal-title":"Biodegradation"},{"key":"2022091514111089400_WST-EM211498C2","doi-asserted-by":"crossref","first-page":"462","DOI":"10.1016\/j.scitotenv.2017.09.290","article-title":"Degradation of nonylphenol polyethoxylates by functionalized Fe3O4 nanoparticle-immobilized sphingomonas sp.
