Secundilactobacillus

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]

• 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

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]
