Abstract

A Gram-stain-negative, yellow-pigmented bacterium, designated as L7, was isolated from seeds of Shap., a leguminous plant that grows in northwest PR China. Strain L7 was found to be non-flagellated, non-spore forming rods which can grow at 10-37 °C, pH 6.0-8.5 and in 0-3 % (v/w) NaCl concentration. The 16S rRNA gene sequence analysis showed that strain L7 belongs to the genus with sequence similarities to GIMN1.005 (98.1%), NCCTC13530 (98.0%), LMG 22846 (97.9%), NCTC13529 (97.7%), DSM 17126 (97.6%) and RSB3-1 (97.5%). The average nucleotide identity of strain L7 to 31 reference strains were 78.6-85.6 %, lower than the species delineation threshold of 95 %. MK-6 was the only respiratory quinone of L7 and major fatty acids were iso-C, iso-C 3-OH, C 7 and/or C 6, isoC 9 and/or C 10-methyl. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, three unidentified aminophospholipids, two unidentified aminolipids, three unidentified glycolipids and two unidentified lipids. The G+C content of the genome was 38.58 mol%. On the basis of polyphasic taxonomy analyses in this study, strain L7 is considered to represent a novel species in the genus , for which the name sp. nov. is proposed. The type strain is L7 (=MCCC 1K05687=JCM 34506).

摘要

一株革兰氏阴性、黄色着色的细菌,被命名为 L7,是从中国西北部一种豆科植物的种子中分离出来的。菌株 L7 被发现是无鞭毛、不产芽孢的杆状菌,能够在 10-37°C、pH6.0-8.5 和 0-3%(v/w)NaCl 浓度下生长。16S rRNA 基因序列分析表明,菌株 L7 属于 属,与 GIMN1.005(98.1%)、NCCTC13530(98.0%)、LMG 22846(97.9%)、NCTC13529(97.7%)、DSM 17126(97.6%)和 RSB3-1(97.5%)的相似度最高。与 31 株参考菌株的平均核苷酸同一性为 78.6-85.6%,低于 95%的种系划分阈值。MK-6 是 L7 的唯一呼吸醌,主要脂肪酸为 iso-C、iso-C 3-OH、C 7 和/或 C 6、isoC 9 和/或 C 10-甲基。主要极性脂为磷脂酰乙醇胺、磷脂酰甘油、三种未鉴定的氨基磷脂、两种未鉴定的氨基脂、三种未鉴定的糖脂和两种未鉴定的脂。基因组的 G+C 含量为 38.58mol%。基于本研究中的多相分类学分析,菌株 L7 被认为代表了 属中的一个新种,因此提议使用 sp. nov. 来命名该新种。模式菌株为 L7(=MCCC 1K05687=JCM 34506)。
