sp. nov., isolated from tungsten mine tailing.

A novel pink-pigmented strain, designated 6HR-1, was isolated from tungsten mine tailings in Jiangxi Province, PR China. Cells were Gram-stain-negative, aerobic, non-spore-forming, rod-shaped and motile with a polar flagellum (monotrichous). It could not utilize methanol, methylamine, formaldehyde or formate as a sole carbon source. The methanol dehydrogenase gene was absent but the gene was present. Phylogenomic and 16S rRNA gene phylogenetic analyses clearly showed that strain 6HR-1 was affiliated to the genus and closely related to '' 17Sr1-28 (98.6 %), JCM 14648 (97.7 %), DSM 16961 (97.7 %) and KACC 19662 (97.4 %). The average nucleotide identity and digital DNA-DNA hybridization values between strain 6HR-1 and its closely related type species were 87.4-88.7 and 33.2-36.3 %, respectively. It had summed feature 8 (C ω7 and/or C ω6) as the major fatty acid and ubiquinone 10 as the predominant respiratory quinone. Polyphasic characterization supported that strain 6HR-1 represents a novel species of the genus , for which the name sp. nov. is proposed with the type strain 6HR-1 (=GDMCC 1.662=KCTC 42760).
