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).

Inorganic compounds that contain tungsten as an integral part of the molecule.
Tungsten. A metallic element with the atomic symbol W, atomic number 74, and atomic weight 183.85. It is used in many manufacturing applications, including increasing the hardness, toughness, and tensile strength of steel; manufacture of filaments for incandescent light bulbs; and in contact points for automotive and electrical apparatus.
Persons who work in a mine to extract ore or MINERALS from the earth.
Organisms used to determine measurable environmental risks or hazards to human health and or well-being, thereby serving as advance or early warning signs of impending danger to humans. Examples of sentinel species are monkeys, guinea pigs, and the fabled canary in the coal mine.
Tungsten hydroxide oxide phosphate. A white or slightly yellowish-green, slightly efflorescent crystal or crystalline powder. It is used as a reagent for alkaloids and many other nitrogen bases, for phenols, albumin, peptone, amino acids, uric acid, urea, blood, and carbohydrates. (From Merck Index, 11th ed)
