Abstract
Three novel strains, designated LB3P45T, LS2P90T and ZS1P70T, were isolated from glaciers located on the Tibetan Plateau, PR China. These strains were Gram-stain-negative, aerobic, rod-shaped and yellow or orange coloured. Phylogenetic analysis based on the 16S rRNA gene and genomic sequences indicated that they belong to the genus Flavobacterium. The 16S rRNA gene sequence similarity among the three strains ranged from 97.4 to 98.6%. Strain LB3P45T showed 98.9% and 98.7% similarity to Flavobacterium urumqiense CGMCC 1.9230T and Flavobacterium xinjiangense JCM 11314T, respectively. Strain LS2P90T displayed 99.0% and 98.7% similarity to F. xinjiangense JCM 11314T and F. urumqiense CGMCC 1.9230T. Strain ZS1P70T had the highest sequence similarity with F. xinjiangense JCM 11314T (98.0%) and F. urumqiense CGMCC 1.9230T (97.8%). The average nucleotide identity and digital DNA-DNA hybridization values between these strains and their closest relatives were lower than 93.0% and 47.9%, respectively. All three strains contained summed feature 3 (comprising C16:1ω7c and/or C16:1ω6c) as the major fatty acids. Based on phenotypic characteristics, phylogenetic analysis and genotypic data, the three novel species are proposed: Flavobacterium fructosi sp. nov. (LB3P45T=CGMCC 1.11439T=NBRC 114819T), Flavobacterium xylosi sp. nov. (LS2P90T=CGMCC 1.11685T=NBRC 114823T) and Flavobacterium zhouii sp. nov. (ZS1P70T=CGMCC 1.24124T=NBRC 114829T).
期刊介绍：
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
