Abstract

A Gram-stain-positive, halotolerant, neutrophilic, rod-shaped bacterium, strain MF38, was isolated from a saline–alkaline soil in China and subjected to a polyphasic taxonomic characterization. The isolate grew in the presence of 0–15 % (w/v) NaCl and at pH 6.5–8.5; optimum growth was observed with 3.0 % (w/v) NaCl and at pH 7.0. Chemotaxonomic analysis showed menaquinone MK-7 as the predominant respiratory quinone and anteiso-C, anteiso-C, iso-C, C and C as major fatty acids. The genomic DNA G+C content was 35.3 mol%. 16S rRNA gene sequence similarities of strain MF38 with type strains of described species ranged from 95.3 to 97.7 %. Strain MF38 exhibited the closest phylogenetic affinity to the type strain of , with 97.7 % 16S rRNA gene sequence similarity. The DNA–DNA reassociation between strain MF38 and DSM 11125 was 45 %. On the basis of phenotypic and genotypic data, strain MF38 represents a novel species of the genus , for which the name sp. nov. (type strain MF38 =CGMCC 1.7727 =JCM 15711) is proposed.
