Isoptericola salitolerans sp. nov., a halotolerant filamentous actinobacterium isolated from a salt lake, China.

A novel bacterial strain, TRM F109(T), 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 F109(T) 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 F109(T) represents a novel species of the genus Isoptericola, for which the name Isoptericola salitolerans sp. nov. is proposed. The type strain is TRM F109(T) (=JCM 15901(T)=KCTC 19617(T)).
