Abstract

A Gram-stain-positive, non-motile, rod-shaped bacterium (strain JC303) isolated from a salt pan was identified based on 16S rRNA gene sequence analysis as a member of the genus . It was related most closely to ASL-1 (99.1 % similarity), YKJ-13 (97.9 %), JSM 081008 (97.9 %), D5 (97.8 %), DSM 1297 (96.3 %), SF-57 (96.1 %) and P9 (94.9 %). Genomic relatedness based on DNA–DNA hybridization of strain JC303 with the type strains of the closest related species was less than 40 %. Diphosphatidylglycerol, three aminophospholipids, an unidentified aminoglycolipid, two unidentified phospholipids and an unidentified lipid were the polar lipids of strain JC303. Major (>10 %) fatty acids were anteiso-C, iso-C and iso-C. Cell-wall amino acids contained peptidoglycan with -lysine as the diagnostic diamino acid. Strain JC303 contained MK-7 as the predominant (96 %) menaquinone with the presence of a significant amount (4 %) of MK-8. The DNA G+C content was 43 mol%. On the basis of morphological, physiological, genotypic, phylogenetic and chemotaxonomic analyses, strain JC303 is considered to represent a novel species of the genus for which the name sp. nov. is proposed. The type strain is JC303 (=KCTC 33662=LMG 28756). In addition, we propose to rename (Chen , 2010), an illegitimate homonym of the validly published name (Cunha , 2012) as sp. nov. with type strain JSM 081008 (=DSM 22174=KCTC 13528).
