  • 🧍 In subsequent papers Kitahara and co-workers referred to the organism as Sporolactobacillus inulinus, elevating Sporolactobacillus to generic rank. Kitahara and Toyota (1972) in a footnote state: "The name Sporolactobacillus is considered more appropriate to be raised to a genus of the familly Bacillaceae from a subgenus of the genus Lactobacillus ...". The Approved Lists of Bacterial Names cite Kitahara and Suzuki 1963 as the authors of the generic name and Kitahara and Lai 1967 as authors of the type species name.

  • 🧍 Sporolactobacillus inulinus, the type species of the genus Sporolactobacillus, was originally named Sporolactobacillus (subgen. Lactobacillus) inulinus thus inadvertently reducing Lactobacillus to subgeneric rank. Publication: Buchanan RE, Gibbons NE. Editorial Note. In: Buchanan RE, Gibbons NE (eds), Bergey's Manual of Determinative Bacteriology, eighth edition, The Williams & Wilkins Co, Baltimore, 1974, p. 551.
  • 🧍 This presumably was a lapsus calami for Lactobacillus (subgen. Sporolactobacillus) inulinus. Publication: Sneath PHA, Mair NS, Sharpe ME, Holt JG. Editorial Note.
