Salirhabdus salicampi sp nov., a halotolerant bacterium isolated from a saltern

A Gram-stain-positive, halotolerant bacterium, designated strain BH128(T), was isolated from soil of a saltern located at Bigeum Island in south-west Korea. Cells were aerobic, motile, spore-forming rods and grew at 15-53 degrees C (optimum, 35 degrees C), at pH 5.5-9.0 (optimum, pH 7.0) and at salinities of 0-16% (w/v) NaCl (optimum, 8% NaCl). The predominant isoprenoid quinone was menaquinone-7 (MK-7), and the cell-wall peptidoglycan type was A1 gamma, with meso-diaminopimelic acid as the diagnostic diamino acid. The major fatty acids were iso-C-15 (:) (0), anteiso-C-15 (:) (0), iso-C-17 (:) (0) and anteiso-C-17 (:) (0). The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and four unknown phospholipids. The DNA G+C content was 36.5 mol%. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain BH128(T) belonged to the genus Salirhabdus and showed highest similarity to Salirhabdus euzebyi CVS-14(T) (95.8 %). On the basis of the phylogenetic, phenotypic and chemotaxonomic analyses in this study, strain BH128(T) is considered to represent a novel species of the genus Salirhabdus, for which the name Salirhabdus salicampi sp. nov. is proposed. The type strain is BH128(T) (=KACC 18690(T)=NBRC 111874(T)).
