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
  • 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%.[1]
