Abstract

A novel lactic acid bacterium, OKN36^T, was isolated from the bark of Entada phaseoloides on Amami Island in Japan. Strain OKN36^T is characterized as a Gram-stain-positive, non-motile, catalase-negative, heterofermentative, and rod-shaped bacterium. The strain grew at temperatures ranging from 10 to 37 °C, in a pH range of 4.0-8.0, and in the presence of 0-6.5% (w/v) NaCl. Phylogenetic analysis using the 16S rRNA gene analysis revealed that strain OKN36^T belongs to the Furfurilactobacillus group. The average nucleotide identity (ANI) and the digital DNA-DNA hybridization (dDDH) values between strain OKN36^T and type strains of validly published Furfurilactobacillus species were 71.83-73.85% and 19.7-20.6%, respectively. These values are below the cutoff of species differentiation, which is 95-96% for ANI and 70% for dDDH. Based on these data, we propose a novel species, named Furfurilactobacillus entadae sp. nov., with the type strain OKN36^T (= JCM 37107^T = DSM 118293^T).

从齿状芽胞杆菌树皮中分离的齿状芽胞杆菌。

摘要从日本奄美岛产的一种新型乳酸菌OKN36T的树皮中分离得到。菌株OKN36T的特征是革兰氏染色阳性，无运动，过氧化氢酶阴性，异源发酵，棒状细菌。菌株生长温度为10 ~ 37℃，pH值为4.0 ~ 8.0，NaCl浓度为0 ~ 6.5% （w/v）。采用16S rRNA基因进行系统发育分析，发现菌株OKN36T属于Furfurilactobacillus类群。菌株OKN36T与有效发表的Furfurilactobacillus种型菌株的平均核苷酸一致性（ANI）和数字DNA-DNA杂交（dDDH）值分别为71.83 ~ 73.85%和19.7 ~ 20.6%。这些值低于物种分化的临界值，ANI为95-96%，dDDH为70%。在此基础上，我们提出了一个新种，命名为Furfurilactobacillus entadae sp. nov.，其类型为OKN36T （= JCM 37107T = DSM 118293T）。
