Secundilactobacillus Explained

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] 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:^[1]

• 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%.
