Secundilactobacillus is a genus of lactic acid bacteria containing secondary fermenters separated from the primary fermenters of Lactobacillus after the latter group depletes hexoses and disaccharides.[1][2] These Gram-positive, rod-shaped heterofermenters have been isolated from beer and apple cider, and they are generally incapable of reducing fructose to mannitol.[1]

Phylogenetic relationships of twelve species reclassified by Zheng et al. 2020

Using whole-genome sequencing, Zheng et al. 2020 reclassified twelve Lactobacillus species into the novel genera Secundilactobacillus. The List of Prokaryotic names with Standing in Nomenclature (LPSN) currently recognizes fifteen member species:[1][2]

These species have genomes sizes ranging from 1.85 Mbp for S. oryzae to 3.62 Mbp for S. collinoides, and their GC-content ranges from 41.03-47%.[1]
