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

A Gram-stain-positive, halotolerant bacterium, designated strain BH128T, 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 °C (optimum, 35 °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 A1γ, with meso-diaminopimelic acid as the diagnostic diamino acid. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0 and anteiso-C17 : 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 BH128T belonged to the genus Salirhabdus and showed highest similarity to Salirhabduseuzebyi CVS-14T (95.8 %). On the basis of the phylogenetic, phenotypic and chemotaxonomic analyses in this study, strain BH128T is considered to represent a novel species of the genus Salirhabdus, for which the name Salirhabdussalicampi sp. nov. is proposed. The type strain is BH128T (=KACC 18690T=NBRC 111874T).
