Abstract

A Gram-stain-negative, rod-shaped, motile, endospore-forming, facultatively anaerobic bacterium, designated strain L14, was isolated from the traditional acetic acid fermentation culture of Chinese cereal vinegars. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain L14 was affiliated to the genus , most closely related to MC10 with 97.8 % similarity. Chemotaxonomic characterization supported the allocation of the strain to the genus . The polar lipid profile of strain L14 contained the major compounds diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The predominant menaquinone was MK-7, and the major fatty acid components were anteiso-C, iso-C and C. The DNA G+C content of strain L14 was 49.9 mol%. The DNA–DNA relatedness value between strain L14 and MC10 was 51.2 %. The results of physiological and biochemical tests allowed phenotypic differentiation of strain L14 from closely related species. On the basis of phenotypic and chemotaxonomic analyses, phylogenetic analysis and DNA–DNA relatedness values, strain L14 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is L14 (=CGMCC 1.15420=JCM 31170).
