Phylogenetic analysis of the 16S rRNA gene sequence of these strains indicated that they represent a novel species in a new genus of the phylum <jats:italic>Betaproteobacteria<\/jats:italic>. The major fatty acids of strains TU-16<jats:sup>T<\/jats:sup> and TU-18 were 16\u200a:\u200a0 and 18\u200a:\u200a1<jats:italic>\u03c9<\/jats:italic>7<jats:italic>c<\/jats:italic>. Ubiquinone 8 was the major respiratory quinone and the major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The novel isolates were aerobic; thiosulfate was oxidized to sulfate in the presence of a metabolizable carbon source. The organism assimilated organic acids and amino acids, but did not assimilate carbohydrates or polyols. Based on phylogenetic analyses and physiological and biochemical characteristics, it is proposed that strain TU-16<jats:sup>T<\/jats:sup> (=LMG 23030<jats:sup>T<\/jats:sup>=CIP 108724<jats:sup>T<\/jats:sup>) represents the type strain of a novel species in a new genus, <jats:italic>Tepidicella xavieri<\/jats:italic> gen. nov., sp. nov.<\/jats:p>","DOI":"10.1099\/ijs.0.64193-0","type":"journal-article","created":{"date-parts":[[2006,4,3]],"date-time":"2006-04-03T22:23:09Z","timestamp":1144102989000},"page":"907-912","source":"Crossref","is-referenced-by-count":25,"title":["Tepidicella xavieri gen. nov., sp. nov., a betaproteobacterium isolated from a hot spring runoff"],"prefix":"10.1099","volume":"56","author":[{"given":"Luis","family":"Fran\u00e7a","sequence":"first","affiliation":[{"name":"Departamento de Bioqu\u00edmica, Universidade de Coimbra, 3001-401 Coimbra, Portugal"}]},{"given":"Fred A.","family":"Rainey","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Louisiana State University, Baton Rouge, LA 70803, USA"}]},{"given":"M.
