  Notes:
  - 🫂 Emendation accompanied by a proposal regarding the synonymy of the species.

Notes:
- ⏰ According to Dellaglio et al. (2004), this species is an earlier heterotypic synonym of Lactobacillus cellobiosus Rogosa et al. 1953 (Approved Lists 1980). Publication: Dellaglio F, Torriani S, Felis GE. Reclassification of Lactobacillus cellobiosus Rogosa et al. 1953 as a later synonym of Lactobacillus fermentum Beijerinck 1901. Int J Syst Evol Microbiol 2004; 54:809-812. 🇮🇹
- ❗ Lactobacillus fermentum is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Lactobacillus.
