sp. nov., a psychrotolerant bacterium isolated from Renlongba glacier on the Tibetan Plateau.

One aerobic, Gram-stain-negative, rod-shaped bacterium, designated strain RB1R5, was isolated from Renlongba glacier in Tibet Autonomous Region, China. Growth was observed at 4-25 °C and pH 7.0-8.0. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain RB1R5 belongs to the genus , and its closest relatives are IMCC26026 and CCM 8827 with 97.75 and 97.42% gene sequence similarities, respectively. The average nucleotide identity and DNA-DNA hybridization values between strain RB1R5 and its closest relative IMCC26026 were 78.02 and 21.8 %, respectively. The major cellular fatty acids were anteiso-C and summed feature 3 (comprising Cω7/Cω6). The sole menaquinone was MK-6. The major phospholipid was phosphatidylethanolamine. On the basis of phenotypic, phylogenetic and chemotaxonomic characterizations, strain RB1R5 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is RB1R5 (=CGMCC 1.23024=NBRC 113060).
