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).

Importance: Influenza vaccination remains the most important intervention to prevent influenza morbidity and mortality among nursing home residents. The additional effectiveness of recombinant influenza vaccine vs standard dose vaccines was demonstrated in outpatient older adults but has not been evaluated in nursing home populations.
Objective: To compare hospitalization rates among residents in nursing homes immunized with a recombinant vs a standard dose egg-based influenza vaccine.

Doramectin, a 16-membered macrocyclic lactone that is widely used in the treatment of mammalian parasitic diseases. Doramectin was produced by mutant using cyclohexanecarboxylic acid as a precursor. As a semi-synthetic insecticidal agent produced, the production of doramectin was low, which could not be satisfy the demands of industrial fermentation.
