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. These Gram-positive, rod-shaped heterofermenters have been isolated from beer and apple cider, and they are generally incapable of reducing fructose to mannitol.
Species
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: Secundilactobacillus angelensis Zhang et al. 2022 Secundilactobacillus collinoides (Carr and Davies 1972) Zheng et al. 2020 Secundilactobacillus folii Phuengjayaem et al. 2021 Secundilactobacillus hailunensis Liu et al. 2021 Secundilactobacillus kimchicus (Liang et al. 2011) Zheng et al. 2020 Secundilactobacillus malefermentans (Farrow et al. 1989) Zheng et al. 2020 Secundilactobacillus mixtipabuli (Tohno et al. 2015) Zheng et al. 2020 Secundilactobacillus odoratitofui (Chao et al. 2010) Zheng et al. 2020 Secundilactobacillus oryzae (Tohno et al. 2013) Zheng et al. 2020 Secundilactobacillus paracollinoides (Suzuki et al. 2004) Zheng et al. 2020 Secundilactobacillus pentosiphilus (Tohno et al. 2017) Zheng et al. 2020 Secundilactobacillus silagei (Tohno et al. 2013) Zheng et al. 2020 Secundilactobacillus silagincola (Tohno et al. 2017) Zheng et al. 2020 Secundilactobacillus similis (Kitahara et al. 2010) Zheng et al. 2020 Secundilactobacillus yichangensis Liu et al. 2021
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%.
