title: Chryseobacterium zhengzhouense sp. nov., isolated from groundwater of the well in a vegetable field, and emended description of the genus Chryseobacterium.
abstract: A Gram-negative, strictly aerobic, non-motile, asporogenous rod-shaped bacterium, designated M05W1-39A1(T), was isolated from a Chinese cabbage farmland located in Zhengzhou. China, and subjected to a taxonomic study. Strain M05W1-39A1(T) 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 M05W1-39A1(T) belongs to the genus Chryseobacterium and is closely related to Chryseobacterium arachidis LMG 27813(T) (98.8 %) and Chryseobacterium geocarposphaera LMG 27811(T) (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 M05W1-39A1(T) 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 M05W1-39A1(T) (=HNMC11208(T) = CGMCC 1.15067(T) = JCM 30863(T)).
