Abstract

Eight facultatively anaerobic rod-shaped bacteria were isolated from raw milk and two other dairy products. Results of phylogenetic analyses based on 16S rRNA gene sequences showed that the isolates are placed in a distinct lineage within the family with and as the closest relatives (94.6 and 93.5 % similarity, respectively). The cell-wall peptidoglycan contained -diaminopimelic acid, alanine and glutamic acid and was of the A1γ type (-DAP-direct). The major cellular fatty acid was anteiso-C and the major polar lipids were diphosphatidylglycerol, phosphatidyglycerol and three unidentified glycolipids. The quinone system contained predominantly menaquinone MK-9(H). The G+C content of the genomic DNA of strain VG341 was 67.7 mol%. The whole-cell sugar pattern contained ribose, rhamnose, arabinose and galactose. On the basis of phenotypic and genetic data, eight strains (VG341, WS4684, WS4769, WS 4882, WS4883, WS4901, WS4902 and WS4904) are proposed to be classified as members of a novel species in a new genus of the family , for which the name gen. nov., sp. nov. is proposed. The type strain is VG341 (=WS4900=DSM 100885=LMG 29089) and seven additional strains are WS4684, WS4769, WS4882, WS4883, WS4901, WS4902 and WS4904. Furthermore, we propose the reclassification of as comb. nov.

摘要

从生牛乳和另外两种乳制品中分离到了 8 株兼性厌氧的杆状细菌。基于 16S rRNA 基因序列的系统发育分析结果表明,这些分离株位于与 关系最近的一个分支(相似性分别为 94.6%和 93.5%)。细胞壁肽聚糖含有 -二氨基庚二酸、丙氨酸和谷氨酸,且属于 A1γ 型(-DAP 直接)。主要的细胞脂肪酸为 anteiso-C,主要的极性脂类为双磷脂酰甘油、磷脂酰甘油和三种未鉴定的糖脂。醌类物质主要含有menaquinone MK-9(H)。菌株 VG341 的基因组 DNA G+C 含量为 67.7 mol%。全细胞糖模式含有核糖、鼠李糖、阿拉伯糖和半乳糖。基于表型和遗传数据,将 8 株菌(VG341、WS4684、WS4769、WS4882、WS4883、WS4901、WS4902 和 WS4904)归类为一个新属中的一个新种的成员,建议将其命名为 ,新种名。模式菌株为 VG341(=WS4900=DSM 100885=LMG 29089),另外 7 株分别为 WS4684、WS4769、WS4882、WS4883、WS4901、WS4902 和 WS4904。此外,我们建议将 重新分类为 。
