In the context of a study on the occurrence of species in an animal farm environment in Valencia, Spain, six -like isolates could not be assigned to any known species. Phylogenetic analysis based on the 16S rRNA gene and on 231 core genes grouped these isolates in a monophyletic clade within the genus , with highest similarity to . Whole-genome sequence analyses based on DNA-DNA hybridization, the average nucleotide blast and the pairwise amino acid identities against all currently known species confirmed that these isolates constituted a new taxon within the genus . Phenotypically, these isolates differed from other species mainly by the production of acid from inositol, the absence of acidification in presence of methyl α-d-glucoside, and the absence of α-mannosidase and nitrate reductase activities. The name sp. nov. is proposed for this novel species, and the type strain is CLIP 2019/00642 (=CIP 111799=DSM 110544).
在西班牙瓦伦西亚一个动物农场环境中 物种发生的研究背景下，有 6 株类似的分离株无法被分配到任何已知的物种。基于 16S rRNA 基因和 231 个核心基因的系统发育分析将这些分离株聚在一个单系分支内，与 最为相似。基于 DNA-DNA 杂交、平均核苷酸比对和与所有当前已知 物种的成对氨基酸同一性的全基因组序列分析证实，这些分离株构成了该属内的一个新分类群。表型上，这些分离株与其他 种主要区别在于能够从肌醇产酸、在存在甲基 α-d-葡糖苷时不酸化以及缺乏 α-甘露糖苷酶和硝酸盐还原酶活性。提议将这个新种命名为 sp. nov.，其模式菌株为 CLIP 2019/00642(=CIP 111799=DSM 110544)。
