Abstract

A novel lactic acid bacterial strain (designated N163-3-2^T), isolated from traditional Chinese pickle ('Suan cai'), was characterized using a polyphasic approach. Strain N163-3-2^T was most closely related to the type strains of Lacticaseibacillus baoqingensis, Lacticaseibacillus manihotivorans, and Lacticaseibacillus porcinae, having 97.9-98.4% 16S rRNA gene, 82.0-85.1% pheS, 87.5-87.8% rpoA, and 85.8-86.7% concatenated pheS and rpoA sequence similarities. Strain N163-3-2^T had 74.4-81.7% ANI, 22.6-23.9% dDDH, and 74.0-75.1% AAI values with L. baoqingensis 47-3^T, L. manihotivorans DSM 13343^T and L. porcinae JCM 19617^T, less than the threshold for species demarcation (95-96%, 70% and 95-96%, respectively), indicating that strain N163-3-2^T represented a novel species of the genus Lacticaseibacillus. Based upon the data obtained in the present study, a novel species, Lacticaseibacillus jixiensis sp. nov., is proposed, and the type strain is N163-3-2^T (= CCTCC AB 2024125^T = JCM 36999^T).

从中国传统泡菜中分离出的吉溪乳酸菌（Lacticaseibacillus jixiensis sp.

采用多相法对从中国传统酱菜（"川菜"）中分离出的一株新型乳酸菌（命名为 N163-3-2T）进行了鉴定。菌株 N163-3-2T 与宝清乳酸杆菌、马尼霍特氏乳酸杆菌和猪乳酸杆菌的模式菌株亲缘关系最密切，16S rRNA 基因相似度为 97.9-98.4%，pheS 相似度为 82.0-85.1%，rpoA 相似度为 87.5-87.8%，pheS 和 rpoA 连接序列相似度为 85.8-86.7%。菌株 N163-3-2T 与 L. baoqingensis 47-3T、L. manihotivorans DSM 13343T 和 L. porcinae JCM 19617 的 ANI 值为 74.4-81.7%，dDDH 值为 22.6-23.9%，AAI 值为 74.0-75.1%。分别为 95-96%、70% 和 95-96%），表明菌株 N163-3-2T 代表了乳酸杆菌属的一个新物种。根据本研究获得的数据，提出了一个新种，即 Lacticaseibacillus jixiensis sp.nov.，模式菌株为 N163-3-2T (= CCTCC AB 2024125T = JCM 36999T)。
