The cell-wall peptidoglycan contained 2,4-diaminobutyric acid as the diamino acid and ribose, rhamnose, glucose and galactose were the major cell-wall sugars. Based on phenotypic, genotypic and phylogenetic evidence, strain WY-16<sup>T</sup> represents a novel species in the genus <i>Salinibacterium</i>, for which the name <i>Salinibacterium soli</i> sp. nov. is proposed. The type strain is WY-16<sup>T</sup> (=GDMCC 1.4011<sup>T</sup>=JCM 36421<sup>T</sup>).</p>","PeriodicalId":14390,"journal":{"name":"International journal of systematic and evolutionary microbiology","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141787987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
