Abstract

A Gram-negative, aerobic, rod-shaped, non-motile bacterium, designated BZ42(T), was isolated from the soil of an industrial site. Strain BZ42(T) was able to grow at 5-25 °C. The major fatty acids were iso-C(15 : 0) (46.2 %), C(16 : 1)ω7c and/or iso-C(15 : 0) 2-OH (23.2 %) and iso-C(17 : 0) 3-OH (9.1 %). The predominant menaquinone was MK-7. The genomic DNA G+C content was 36.5 mol% (HPLC). 16S rRNA gene sequence phylogenetic analysis revealed that strain BZ42(T) was a member of the genus Pedobacter, family Sphingobacteriaceae, and 16S rRNA gene sequence similarities between strain BZ42(T) and the type strains of species of the genus Pedobacter with validly published names were 90.4-93.2 %. On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain BZ42(T) was considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter bauzanensis sp. nov. is proposed. The type strain is BZ42(T) (=DSM 22554(T) =CGMCC 1.10187(T) =CIP 110134(T)).

摘要

一株革兰氏阴性、需氧、杆状、非运动细菌,被命名为 BZ42(T),从一个工业场地的土壤中分离得到。BZ42(T) 菌株能够在 5-25°C 下生长。主要脂肪酸为 iso-C(15 : 0) (46.2 %)、C(16 : 1)ω7c 和/或 iso-C(15 : 0) 2-OH (23.2 %)和 iso-C(17 : 0) 3-OH (9.1 %)。主要的menaquinone 为 MK-7。基因组 DNA G+C 含量为 36.5 mol% (HPLC)。16S rRNA 基因序列系统发育分析显示,BZ42(T) 菌株是 Pedobacter 属、鞘氨醇单胞菌科的成员,与已发表有效名称的 Pedobacter 属种的模式菌株的 16S rRNA 基因序列相似性为 90.4-93.2 %。基于表型、化学分类和系统发育的独特性,BZ42(T) 菌株被认为代表了 Pedobacter 属的一个新种,因此建议将其命名为 Pedobacter bauzanensis sp. nov.。该模式菌株为 BZ42(T) (=DSM 22554(T) =CGMCC 1.10187(T) =CIP 110134(T))。
