sp. nov., a moderately halophilic bacterium from a subterranean brine Free

Abstract

A moderately halophilic, endospore-forming, Gram-positive, catalase- and oxidase-positive, motile, rod-shaped, aerobic bacterium, designated strain JSM 078133, was isolated from a subterranean brine sample collected from a salt mine in Hunan Province, China. Strain JSM 078133 was able to grow with 1–23 % (w/v) total salts (optimum, 5–10 %) and at pH 6.0–10.0 (optimum, pH 7.5) and 10–45 °C (optimum, 30 °C). -Diaminopimelic acid was present in the cell-wall peptidoglycan. The predominant respiratory quinone was menaquinone 7 (MK-7) and the major cellular fatty acids were anteiso-C, anteiso-C and iso-C. The genomic DNA G+C content of strain JSM 078133 was 42.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain JSM 078133 belongs to the genus , and was related most closely to the type strains of (97.1 % sequence similarity), (97.0 %) and (96.8 %). The combination of phylogenetic analysis, DNA–DNA relatedness data, phenotypic characteristics and chemotaxonomic data supported the view that strain JSM 078133 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is JSM 078133 (=DSM 21185=KCTC 13236).
