Abstract

A Gram-stain-variable, motile, moderately halophilic bacterial strain, CHL-21, was isolated from a marine solar saltern and its taxonomic position was investigated using a polyphasic approach. Optimal growth of strain CHL-21 occurred at 30–37 °C, at pH 7.0–7.5 and in the presence of 5–10 % (w/v) NaCl. In phylogenetic trees based on 16S rRNA gene sequences, strain CHL-21 fell within the cluster comprising members of the genera , and . Strain CHL-21 exhibited 97.1–97.2 % 16S rRNA gene sequence similarity to the type strains of the two subspecies of and 92.0–94.7 % 16S rRNA gene sequence similarity to the type strains of other members of the genus and members of the genera and . Mean DNA–DNA reassociation values between strain CHL-21 and the type strains of the two subspecies of were 19–21 %. The cell-wall peptidoglycan of strain CHL-21 was based on -diaminopimelic acid, MK-7 was the predominant menaquinone, and anteiso-C and anteiso-C were the major fatty acids. The DNA G+C content was 39.8 mol%. Differential phenotypic properties, including facultatively anaerobic growth and acid production from substrates, together with its phylogenetic and genetic distinctiveness, demonstrated that strain CHL-21 is distinguishable from recognized species. On the basis of data presented, strain CHL-21 represents a novel species within the genus , for which the name sp. nov. is proposed; the type strain is CHL-21 (=KCTC 13253 =CCUG 56608).
