This study presents a novel strain, SNU WT3, isolated from the kidney of rainbow trout. A phylogenetic study using 16S rRNA sequences indicated that the strain is closely related to JA-1. However, biochemical analysis found differences in D-xylose adonitol, N-acetylglucosamine, arbutin, and cellobiose. As for genome-to-genome distance and average nucleotide identity values calculated between strain SNU WT3 and other related strains such as EIF1, PAMC 27463, and BHSEK were all below the cutoff value between species. DNA-DNA hybridization between strain SNU WT3 and other close relatives indicated the results of DSM 1522 (47.11%) and JA-1 (38.88%) individually. The major fatty acid compositions of strain SNU WT3 were cylco-C (41.45%), C (33.86%) and C (5.87%). The major polar lipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, and diphosphatidylglycerol. The quinone system was composed mainly of ubiquinone Q-8. The genome of strain SNU WT3 consists of 6,314,370 bp with a G + C content of 62.35%. Here, we describe a novel species of the genus , and the name has been proposed with SNU WT3 (=KCTC 72518 = JCM 33613) as the type strain.
本研究展示了一种从虹鳟鱼肾脏中分离出的新型菌株SNU WT3。使用16S rRNA序列进行的系统发育研究表明，该菌株与JA-1密切相关。然而，生化分析发现其在D-木糖、阿东糖醇、N-乙酰葡糖胺、熊果苷和纤维二糖方面存在差异。至于菌株SNU WT3与其他相关菌株（如EIF1、PAMC 27463和BHSEK）之间计算的全基因组距离和平均核苷酸同一性值均低于物种间的截止值。菌株SNU WT3与其他近亲之间的DNA-DNA杂交分别显示了DSM 1522（47.11%）和JA-1（38.88%）的结果。菌株SNU WT3的主要脂肪酸成分为环丙烷脂肪酸（41.45%）、直链脂肪酸（33.86%）和支链脂肪酸（5.87%）。主要极性脂类为磷脂酰乙醇胺、磷脂酰胆碱、磷脂酰甘油和双磷脂酰甘油。醌系统主要由泛醌Q-8组成。菌株SNU WT3的基因组由6,314,370 bp组成，G + C含量为62.35%。在此，我们描述了一个新的属种，并已提议将SNU WT3（=KCTC 72518 = JCM 33613）作为模式菌株的名称。
