Description of 15 novel species within genus Janthinobacterium isolated from glaciers.

Fifteen Gram-stain-negative, rod-shaped bacterial strains, motile by means of a monopolar flagellum, were isolated from glaciers located on the Tibetan Plateau, P.R. China. These strains, designated MDT1-19T, MDB2-8T, HLS12-2T, HLX7-2T, LB2P49T, LB2P70T, LB3P112T, LB3P118T, LB2P10T, RB2R34T, ZB1P44T, RB2P8T, GB1R12T, GB4P2T and RT4P48T, belong to the genus Janthinobacterium based on 16S rRNA gene sequences analysis. The average nucleotide identity and digital DNA-DNA hybridization values between these strains and species with validly published names were below 96% and 70%, respectively. Based on the phylogenetic, genotypic and phenotypic evidence, these 15 strains are proposed to represent fifteen novel species within the genus Janthinobacterium, with the following proposed names: Janthinobacterium algoris sp. nov. (MDT1-19T=CGMCC 1.9797=NBRC 116353T), Janthinobacterium breve sp. nov. (MDB2-8T=CGMCC 1.9853T=NBRC 116354T), Janthinobacterium darwini sp. nov. (HLS12-2T=CGMCC 1.9980T=NBRC 116355T), Janthinobacterium woesei sp. nov. (HLX7-2T=CGMCC 1.9990T=NBRC 116356T), Janthinobacterium salmonicoloratum sp. nov. (LB2P49T=CGMCC 1.11246T=NBRC 116357T), Janthinobacterium violaceum sp. nov. (LB2P70T=CGMCC 1.11252T=NBRC 116358T), Janthinobacterium leeuwenhoeki sp. nov. (LB3P112T=CGMCC 1.11294T=NBRC 116359T), Janthinobacterium pasteuri sp. nov. (LB3P118T=CGMCC 1.11299T=NBRC 116360T), Janthinobacterium paucivorans sp. nov. (LB2P10T=CGMCC 1.11332T=NBRC 116361T), Janthinobacterium longum sp. nov. (RB2R34T=CGMCC 1.11894T=NBRC 116362T), Janthinobacterium glycogeni sp. nov. (ZB1P44T=CGMCC 1.23234T=NBRC 116363T), Janthinobacterium kochi sp. nov. (RB2P8T=CGMCC 1.23776T=NBRC 116364T), Janthinobacterium goodfellowi sp. nov. (GB1R12T=CGMCC 1.24272T=NBRC 116365T), Janthinobacterium lyxosi sp. nov. (GB4P2T=CGMCC 1.24307T=NBRC 116366T) and Janthinobacterium amylolyticum sp. nov. (RT4P48T=CGMCC 1.24355T=NBRC 116367T).
