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<sup>T</sup>, MDB2-8<sup>T</sup>, HLS12-2<sup>T</sup>, HLX7-2<sup>T</sup>, LB2P49<sup>T</sup>, LB2P70<sup>T</sup>, LB3P112<sup>T</sup>, LB3P118<sup>T</sup>, LB2P10<sup>T</sup>, RB2R34<sup>T</sup>, ZB1P44<sup>T</sup>, RB2P8<sup>T</sup>, GB1R12<sup>T</sup>, GB4P2<sup>T</sup> and RT4P48<sup>T</sup>, belong to the genus <i>Janthinobacterium</i> 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 <i>Janthinobacterium</i>, with the following proposed names: <i>Janthinobacterium algoris</i> sp. nov.
