从日本烧酒渣堆肥中分离得到5株乳酸菌。根据16S rRNA基因序列相似性将分离物分为两组，并形成两个亚群，其包括与布氏乳杆菌（Lactobacillus buchneri）、L. diolivorans，L. hilgardii，L.开菲尔湖parabuchneri和L. parakefiri。DNA-DNA相关性分析结果表明，分离株可分为两大类，这两大类与系统发育分析所得到的亚群具有很好的相关性。此外，DNA-DNA相关性的水平表明，这两个群体从其系统发育亲属中明显分离。因此，这两组代表两个新物种，建议将其命名为Lactobacillus farraginis sp. nov.（模式菌株NRIC 0676（T）= JCM 14108（T）= DSM 18382（T））和Lactobacillus parafarraginis sp. nov.（模式菌株NRIC 0677（T）= JCM 14109（T）= DSM 18390（T））。
Five strains of lactic acid bacteria were isolated from a compost of distilled shochu residue in Japan. The isolates were separated into two groups on the basis of 16S rRNA gene sequence similarity, and two subclusters were formed that comprised micro-organisms closely related to Lactobacillus buchneri, L. diolivorans, L. hilgardii, L. kefiri, L. parabuchneri and L. parakefiri. DNA-DNA relatedness results revealed that the isolates could be separated into two groups, and these groups correlated well with the subclusters generated using the phylogenetic analysis. Moreover, the levels of DNA-DNA relatedness showed clear separation of the two groups from their phylogenetic relatives. Therefore, the two groups represent two novel species, for which the names Lactobacillus farraginis sp. nov. (type strain NRIC 0676(T) = JCM 14108(T) = DSM 18382(T)) and Lactobacillus parafarraginis sp. nov. (type strain NRIC 0677(T) = JCM 14109(T) = DSM 18390(T)) are proposed.
