Abstract

A novel bacterium, designated 1RM2^T, was isolated from Xinjiang Province, north-west PR China. This strain could grow under conditions of 20-45 °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 1RM2^T were strain Chryseobacterium bernardetii NCTC 13530^T (97.1%) and Chryseobacterium daecheongense DSM 15235^T (96.9%). The draft genome sequence G+C content of strain 1RM2^T was 39.5 mol%. The average nucleotide identity and DNA-DNA hybridization values between strain 1RM2^T and the two closest neighbours were 78.6%, 77.6% and 21.8%, 21.2%, respectively. The main fatty acids of strain 1RM2^T were iso-C_15:0, iso-C_17:0 3-OH, summed feature 3 (C_16:1 ω6c and/or C_16:1 ω7c) and summed feature 9 (C_16:0 10-methyl and/or iso-C_17:1 ω9c). 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 1RM2^T is a new species of the genus Chryseobacterium and is proposed to be named Chryseobacterium gossypii sp. nov. (=GDMCC 1.4437^T=KCTC 102275^T).

从长期连作棉田中分离到的一种棉花黄杆菌。

从新疆省分离到一株新型细菌，命名为1RM2T。该菌株可在20 ~ 45℃、pH 5.0 ~ 10.0和0 ~ 10% (w/v) NaCl条件下生长。16S rRNA基因序列与菌株1RM2T相似度最高的种为菌株bernardetii NCTC 13530T（97.1%）和菌株daecheongense DSM 15235T（96.9%）。菌株1RM2T基因组草图序列G+C含量为39.5 mol%。菌株1RM2T与两个最近邻的核苷酸同源性和DNA-DNA杂交值的平均值分别为78.6%、77.6%和21.8%、21.2%。菌株1RM2T的主要脂肪酸为iso-C15:0、iso-C17:0 3- oh、总特征3 （C16:1 ω6c和/或C16:1 ω7c）和总特征9 （C16:0 10-甲基和/或iso-C17:1 ω9c）。主要的类异戊二烯醌为甲基萘醌-6，极性脂质为磷脂酰乙醇胺、未识别的氨基磷脂和未识别的脂质。根据表型特征和基因型分析，菌株1RM2T为黄杆菌属新种，建议将其命名为黄杆菌gossypii sp. nov. （=GDMCC 1.4437T=KCTC 102275T）。

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.
