乳杆菌属包括261种（截至2020年3月），在表型、生态和基因型水平上极其多样化。本研究基于全基因组序列对乳杆菌科和明串珠菌科的分类进行了评价。评价的参数包括核心基因组同源性、（保守的）成对平均氨基酸同一性、Glade特异性标记基因、生理学标准和生物体生态学。基于这种多相方法，我们提出将乳杆菌属重新分类为25个属，包括修正的乳杆菌属，其包括已被称为德氏乳杆菌组、副乳杆菌的宿主适应生物，以及23个新属，其名称为Holzapfelia、淀粉乳杆菌、熊蜂乳杆菌、伴乳杆菌、Lapidiacillus、Agriacillus、Schleiferilacillus、Loigolactobacilus、提出了乳酸杆菌属、乳杆菌属、Dellaglioa属、甘草乳酸杆菌属、Ligilaclactobacillus属、乳酸杆菌属、毛皮乳酸杆菌属、Paucilaclactobacillus属、Limosilaclactobacillus属、Fructibacillus属、Acetibacillus属、Apilaclactobacillus属、Levilaclactobacillus属、Secundibacillus属和Lentibacillus属。我们还建议修订乳酸杆菌科的描述，以包括以前包括在乳酸杆菌科和明串珠菌科的所有属。在2020年之前，“乳酸杆菌”这个通用术语仍然适用于指定所有被归类为乳酸杆菌科的生物。这种重新分类反映了微生物的系统发育地位，并将乳酸杆菌分为具有共同生态和代谢特性的强大分支，例如修订的乳酸杆菌属，包括适应脊椎动物的物种（例如德氏乳杆菌、惰性乳杆菌、卷曲乳杆菌、詹氏乳杆菌，在一些实施方案中，本发明的组合物可用于无脊椎动物（例如约氏乳杆菌和嗜酸乳杆菌）或无脊椎动物（例如蜜蜂乳杆菌和家蚕乳杆菌）。
The genus Lactobacillus comprises 261 species (at March 2020) that are extremely diverse at phenotypic, ecological and genotypic levels. This study evaluated the taxonomy of Lactobacillaceae and Leuconostocaceae on the basis of whole genome sequences. Parameters that were evaluated included core genome phylogeny, (conserved) pairwise average amino acid identity, Glade-specific signature genes, physiological criteria and the ecology of the organisms. Based on this polyphasic approach, we propose reclassification of the genus Lactobacillus into 25 genera including the emended genus Lactobacillus, which includes host-adapted organisms that have been referred to as the Lactobacillus delbrueckii group, Paralactobacillus and 23 novel genera for which the names Holzapfelia, Amylolactobacillus, Bombilactobacillus, Companilactobacillus, Lapidilactobacillus, Agrilactobacillus, Schleiferilactobacillus, Loigolactobacilus, Lacticaseibacillus, Latilactobacillus, Dellaglioa, Liquorilactobacillus, Ligilactobacillus, Lactiplantibacillus, Fur furilactobacillus, Paucilactobacillus, Limosilactobacillus, Fructilactobacillus, Acetilactobacillus, Apilactobacillus, Levilactobacillus, Secundilactobacillus and Lentilactobacillus are proposed. We also propose to emend the description of the family Lactobacillaceae to include all genera that were previously included in families Lactobacillaceae and Leuconostocaceae. The generic term 'lactobacilli' will remain useful to designate all organisms that were classified as Lactobacillaceae until 2020. This reclassification reflects the phylogenetic position of the micro-organisms, and groups lactobacilli into robust clades with shared ecological and metabolic properties, as exemplified for the emended genus Lactobacillus encompassing species adapted to vertebrates (such as Lactobacillus delbrueckii, Lactobacillus iners, Lactobacillus crispatus, Lactobacillus jensensii, Lactobacillus johnsonii and Lactobacillus acidophilus) or invertebrates (such as Lactobacillus apis and Lactobacillus bombicola).
