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.

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%.
