Recently, the members of the genus Lactobacillus have been reclassified by Zheng et al. At the same time, Lactobacillus buchneri subsp. silagei, Lactobacillus zhaodongensis, Lactobacillus argentoratensis and Lactobacillus zeae have been successively and validly published, and Lactobacillus kosoi has also been reclassified. In the present study, all these species and subspecies were re-evaluated by 16S rRNA gene sequence analysis or a combination of 16S rRNA gene sequence analysis and phylogenomic treeing. On the basis of the results presented here, we propose to reclassify Lactobacillus zhaodongensis, Lactobacillus zeae, Lactobacillus argentoratensis and Lactobacillus buchneri subsp. silagei as Lacticaseibacillus zhaodongensis comb. nov., Lacticaseibacillus zeae comb. nov., Lactiplantibacillus argentoratensis comb. nov. and Lentilactobacillus buchneri subsp. silagei comb. nov., respectively and Apilactobacillus kosoi as a later heterotypic synonym of Apilactobacillus micheneri.
