Flavobacterium algoriphilum sp. nov., Flavobacterium arabinosi sp. nov., Flavobacterium cryoconiti sp. nov., Flavobacterium galactosi sp. nov., Flavobacterium melibiosi sp. nov., and Flavobacterium algoris sp. nov., six novel cold-adapted bacteria isolated from glaciers.

ABSTRACT:

Background

Six novel cold-adapted bacteria, LB3P122^T, LT1R49^T, ZT3R17^T, ZT3R25^T, XS2P12^T, and GB2R13^T, were isolated from glaciers on the Tibetan Plateau. This study aimed to characterize their taxonomic status and elucidate their molecular adaptations to cold environments using a polyphasic approach.

Results

All strains were Gram-stain-negative, rod-shaped, and psychrophilic, growing at 0 °C with an optimum at 14-20 °C and at pH values of 6.0-8.0 (optimum pH 7.0). Analysis of the 16S rRNA gene sequences placed their taxonomic positions within the genus Flavobacterium, with similarities ranging from 97.2 to 98.4% to species with validly published names. Phylogenetic analysis of the 16S rRNA gene sequences reve
