It was selected from the community on the basis of its ability to reduce elemental sulfur. The cells are motile, Gram-negative rods (2.0-3.0 microns long, 0.4-0.6 micron wide). ANG-SQ1T grows optimally over the temperature range of 25-30 degrees C and a pH range of 6.5-7.5 degrees C in media containing 0.5 M NaCl. 16S rRNA sequence analysis revealed that this organism belongs to the gamma-3 subclass of the Proteobacteria. The closest relative of ANG-SQ1T is Shewanella gelidimarina, with a 16S rRNA sequence similarity of 97.0%. Growth occurs with glucose, lactate, acetate, pyruvate, glutamate, citrate, succinate, Casamino acids, yeast extract or peptone as sole energy source under aerobic conditions. The isolate grows anaerobically by the reduction of iron, manganese, nitrate, fumarate, trimethylamine-N-oxide, thiosulfate or elemental sulfur as terminal electron acceptor with lactate. Growth of ANG-SQ1T was enhanced by the addition of choline chloride to growth media lacking Casamino acids. The addition of leucine or valine also enhanced growth in minimal growth media supplemented with choline. The results of both phenotypic and genetic characterization indicate that ANG-SQ1T is a Shewanella species. Thus it is proposed that this new isolate be assigned to the genus Shewanella and that it should be named Shewanella pealeana sp. nov., in recognition of its association with L. pealei.</p>","PeriodicalId":14428,"journal":{"name":"International journal of systematic bacteriology","volume":"49 Pt 4 ","pages":"1341-51"},"PeriodicalIF":0.0,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1099/00207713-49-4-1341","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21415858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
