| Abstract: | A novel bacterial strain, TRM F109T, was isolated from hypersaline habitat in Sichuan Province, China. It was a Gram-positive, aerobic, non-motile, halotolerant, filamentous bacterium. Phylogenetic analysis based on 16S rRNA gene sequences revealed levels of similarity of 97.0–98.4 % to the type strains of recognized species of the genus Isoptericola. Chemotaxonomic data also supported the placement of strain TRM F109T within the genus Isoptericola. The low levels of DNA–DNA relatedness between the novel strain and the type strains of recognized species of the genus Isoptericola, in combination with differential phenotypic data, demonstrate that strain TRM F109T represents a novel species of the genus Isoptericola, for which the name Isoptericola salitolerans sp. nov. is proposed. The type strain is TRM F109T (=JCM 15901T=KCTC 19617T). |
