Strain FOL01T was isolated from traditionally fermented Korean jogae jeotgal (fermented clams). Phylogenetic sequence analysis of the 16S rRNA gene from FOL01T revealed that it is closely related to Weissella thailandensis FS61-1T and Weissella paramesenteroides ATCC 33313T with 99.39 % and 98.50 % 16S rRNA gene sequence similarities, respectively. API and VITEK analyses showed that strain FOL01T could be separated from its nearest phylogenetic relatives with respect to carbohydrate fermentation and antibiotic resistance. Subsequent amplified rRNA gene restriction analysis of 16S rRNA genes and HaeIII-restriction enzyme profiling of genomic DNAs revealed different band patterns. In addition, DNA-DNA hybridization of genomic DNAs showed 63.9 % relatedness. Analysis of the composition of cellular fatty acids confirmed that strain FOL01T differs from its close relatives and supports the proposal to assign this organism to a novel species of the genus Weissella. Based on these results, strain FOL01T could be classified as a novel species of the genus Weissella, for which the name Weissella jogaejeotgali sp. nov. is proposed. The type strain is FOL01T ( = KCCM 43128T = JCM 30589T).
菌株FOL01T是从传统发酵的韩国蛤仔酱(发酵蛤蜊)中分离出来的。对FOL01T的16S rRNA基因进行系统发育序列分析表明,它与泰国魏斯氏菌FS61-1T和副肠系膜魏斯氏菌ATCC 33313T密切相关,16S rRNA基因序列相似性分别为99.39%和98.50%。API和VITEK分析表明,菌株FOL01T在碳水化合物发酵和抗生素抗性方面可与其最接近的系统发育亲缘关系菌区分开来。随后对16S rRNA基因进行扩增rRNA基因限制性分析以及对基因组DNA进行HaeIII限制性酶切图谱分析,结果显示出不同的条带模式。此外,基因组DNA的DNA-DNA杂交显示出63.9%的相关性。细胞脂肪酸组成分析证实菌株FOL01T与其近缘菌不同,并支持将该菌株归为魏斯氏菌属一个新物种的提议。基于这些结果,菌株FOL01T可被归类为魏斯氏菌属的一个新物种,为此提议将其命名为蛤仔魏斯氏菌(Weissella jogaejeotgali sp. nov.)。模式菌株为FOL01T(=KCCM 43128T =JCM 30589T)。
