• Notes:
  • ❗ Acetobacter liquefaciens 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 Acetobacter.

  • 🎓 Name mentioned 6 times in PubMed until 2024-03-28.
  • 🧍 On the Validation List no. 12, the type strain IFO (now NBRC) 12388 is erroneously cited as IFO (now NBRC) 2388 (sic). Publication: Euzeby JP, Kudo T. Corrigenda to the validation lists. Int J Syst Evol Microbiol 2001; 51:1933-1938.
  • 🧍 The subgenus Gluconoacetobacter appears in Validation List no. 17 (publication date: 15 April 1985). The nomenclatural type of this subgenus is cited as Acetobacter (subgen. Gluconoacetobacter) liquefaciens. However Acetobacter (subgen. Gluconoacetobacter) liquefaciens is not listed in Validation List no. 17 and this name seems inadvertently to have been omitted from this list. This error has been corrected by Euzéby and Kudo. The date of valid publication of this name is that of List no. 17 (15 April 1985). Publication: Euzeby JP. Nomenclature of the subgenera Moraxella and Branhamella and of the nine species included in these subgenera and proposal to modify rule 34a of the Bacteriological Code (1990 Revision). Request for an opinion. Int J Syst Evol Microbiol 2001; 51:1939-1941.
