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 MDT1-19 T , MDB2-8 T , HLS12-2 T , HLX7-2 T , LB2P49 T , LB2P70 T , LB3P112 T , LB3P118 T , LB2P10 T , RB2R34 T , ZB1P44 T , RB2P8 T , GB1R12 T , GB4P2 T and RT4P48 T , 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. (MDT1-19 T =CGMCC 1.9797=NBRC 116353 T ), Janthinobacterium breve sp. nov. (MDB2-8 T =CGMCC 1.9853 T =NBRC 116354 T ), Janthinobacterium darwini sp. nov. (HLS12-2 T =CGMCC 1.9980 T =NBRC 116355 T ), Janthinobacterium woesei sp. nov. (HLX7-2 T =CGMCC 1.9990 T =NBRC 116356 T ), Janthinobacterium salmonicoloratum sp. nov. (LB2P49 T =CGMCC 1.11246 T =NBRC 116357 T ), Janthinobacterium violaceum sp. nov. (LB2P70 T =CGMCC 1.11252 T =NBRC 116358 T ), Janthinobacterium leeuwenhoeki sp. nov. (LB3P112 T =CGMCC 1.11294 T =NBRC 116359 T ), Janthinobacterium pasteuri sp. nov. (LB3P118 T =CGMCC 1.11299 T =NBRC 116360 T ), Janthinobacterium paucivorans sp. nov. (LB2P10 T =CGMCC 1.11332 T =NBRC 116361 T ), Janthinobacterium longum sp. nov. (RB2R34 T =CGMCC 1.11894 T =NBRC 116362 T ), Janthinobacterium glycogeni sp. nov. (ZB1P44 T =CGMCC 1.23234 T =NBRC 116363 T ), Janthinobacterium kochi sp. nov. (RB2P8 T =CGMCC 1.23776 T =NBRC 116364 T ), Janthinobacterium goodfellowi sp. nov. (GB1R12 T =CGMCC 1.24272 T =NBRC 116365 T ), Janthinobacterium lyxosi sp. nov. (GB4P2 T =CGMCC 1.24307 T =NBRC 116366 T ) and Janthinobacterium amylolyticum sp. nov. (RT4P48 T =CGMCC 1.24355 T =NBRC 116367 T ).
