ABSTRACT
Strain KC 927T was isolated during an investigation of the soil bacteria diversity on Jiaozi Mountain, central Yunnan, Southwest China. The strain was Gram-stain-negative, rod-shaped, non-motile, oxidase-negative, catalase-positive and aerobic. Results of 16S rRNA gene alignment and phylogenetic analysis indicated that strain KC 927T was a member of the genus Chryseobacterium and closely related to Chryseobacterium caseinilyticum GCR10T (98.4%), Chryseobacterium piscicola DSM 21068T (98.3â%) and 'Chryseobacterium formosus' CCTCC AB 2015118T (97.9â%). With a genome size of 4 348 708 bp, strain KC 927T had 33.5âmol% DNA G+C content and contained 4012 protein-coding genes and 77 RNA genes. The average nucleotide identity and digital DNA-DNA hybridization values between strain KC 927T and C. caseinilyticum GCR10T, C. piscicola DSM 21068T and 'C. formosus' CCTCC AB 2015118T were 80.1, 79.6 and 90.7â%, and 25.5, 23.6 and 42.0â%, respectively. The main polar lipid of strain KC 927T was phosphatidylethanolamine and the respiratory quinone was MK-6. The major fatty acids (≥10â%) were iso-C15ââ0, iso-C17ââ1 ω9c and iso-C17ââ0 3-OH. Evidence from phenotypic, phylogenetic and chemotaxonomic analyses support that strain KC 927T represents a new species of the genus Chryseobacterium, for which the name Chryseobacterium luquanense sp. nov. is proposed. The type strain is KC 927T (=CGMCC 1.18760T=JCM 35707T).
