文摘

A Gram-negative, strictly aerobic, non-motile, asporogenous rod-shaped bacterium, designated M05W1-39A1T, was isolated from a Chinese cabbage farmland located in Zhengzhou. China, and subjected to a taxonomic study. Strain M05W1-39A1T was found to grow optimally at 25–30 °C, at pH 6.0–7.0 and in the presence of 0.5–2.0 % (w/v) NaCl. According to phylogenetic analysis using 16S rRNA gene sequences, strain M05W1-39A1T belongs to the genus Chryseobacterium and is closely related to Chryseobacterium arachidis LMG 27813T (98.8 %) and Chryseobacterium geocarposphaera LMG 27811T (98.1 %). The DNA G + C content was determined to be 35.3 mol%. The respiratory quinone was identified as MK-6 and the predominant cellular fatty acids as iso-C15:0, Summed feature 3 (C16:1 ω7c/C16:1 ω6c), iso-C17:0 3-OH and Summed feature 9 (iso-C17:1 ω9c). Based on the genotypic, chemotaxonomic and phenotypic data, strain M05W1-39A1T is concluded to represent a novel species of the genus Chryseobacterium, for which the name Chryseobacterium zhengzhouense sp. nov. is proposed. The type strain is M05W1-39A1T (=HNMC11208T = CGMCC 1.15067T = JCM 30863T).
