Three Gram-positive-staining strains isolated from fermented stinky tofu brine were rod-shaped, non-motile, asporogenous, facultatively anaerobic, heterofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, rpoA and pheS gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence similarity, the type strains of Lactobacillus collinoides (98.6 %), Lactobacillus paracollinoides (98.6 %) and Lactobacillus similis (99.6 %) were the closest neighbours. However, DNA-DNA reassociation values with these strains were less than 10 %. The phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus odoratitofui sp. nov. is proposed. The type strain is YIT 11304(T) (=JCM 15043(T) =BCRC 17810(T) =DSM 19909(T)).
从发酵臭豆腐卤水中分离得到的三株革兰氏阳性染色菌株呈杆状,不运动,无孢子,兼性厌氧,异型发酵,不表现过氧化氢酶活性。16S rRNA、rpoA 和 pheS 基因序列的比较分析表明,这些新菌株是乳杆菌属的成员。基于 16S rRNA 基因序列相似性,模式菌株 Lactobacillus collinoides(98.6%)、Lactobacillus paracollinoides(98.6%)和 Lactobacillus similis(99.6%)是最接近的近缘种。然而,与这些菌株的 DNA-DNA 再结合值小于 10%。表型和基因型特征表明,这些分离株代表了乳杆菌属的一个新种,提议将其命名为 Lactobacillus odoratitofui sp. nov.。模式菌株为 YIT 11304(T)(=JCM 15043(T) =BCRC 17810(T) =DSM 19909(T))。
