摘要： A novel bacterium, designated 1RM2T, was isolated from Xinjiang Province, north- west PR China. This strain could grow under conditions of 20-45 degrees C, pH 5.0-10.0 and 0-10% (w/v) NaCl. The species with the highest similarity of 16S rRNA gene sequences to strain 1RM2T were strain Chryseobacterium bernardetii NCTC 13530T (97.1%) and Chryseobacterium daecheongense DSM 15235T (96.9%). The draft genome sequence G+C content of strain 1RM2T was 39.5 mol%. The average nucleotide identity and DNA-DNA hybridization values between strain 1RM2T and the two closest neighbours were 78.6%, 77.6% and 21.8%, 21.2%, respectively. The main fatty acids of strain 1RM2T were iso- C15:0, iso-C17:0 3- OH, summed feature 3 (C16:1 omega 6c and/or C16:1 omega 7c) and summed feature 9 (C16:0 10- methyl and/or iso- C17:1 omega 9c). The main isoprenoid quinone was menaquinone- 6 and polar lipids were phosphatidylethanolamine, unidentified amino phospholipids and unidentified lipids. Based on phenotypic characteristics and genotype analysis, strain 1RM2T is a new species of the genus Chryseobacterium and is proposed to be named Chryseobacterium gossypii sp. nov. (=GDMCC 1.4437T=KCTC 102275T).
