Abstract

A facultatively anaerobic, moderately halophilic, Gram-positive, endospore-forming, motile, catalase- and oxidase-positive, rod-shaped bacterium, strain JSM 072002, was isolated from a sea anemone () collected from the South China Sea. Strain JSM 072002 was able to grow with 0.5–15 % (w/v) NaCl and at pH 6.0–10.0 and 15–50 °C; optimum growth was observed with 2–5 % (w/v) NaCl and at pH 7.5 and 35 °C. -Diaminopimelic acid was present in the cell-wall peptidoglycan. The major cellular fatty acids were iso-C and anteiso-C. The predominant respiratory quinone was menaquinone 7 and the genomic DNA G+C content was 41.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 072002 should be assigned to the genus and revealed relatively low 16S rRNA gene sequence similarities (<97 %) with the type strains of the three recognized species ( BH030062, 96.8 %; KCTC 3917, 96.7 %; JSM 076056, 96.0 %). The combination of phylogenetic analysis, DNA–DNA relatedness values, phenotypic characteristics and chemotaxonomic data supports the view that strain JSM 072002 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is JSM 072002 (=DSM 21186=KCTC 13237). An emended description of the genus is also presented.
