Propionibacteriumpropionicum is the correct name 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 Propionibacterium.
The original spelling of the specific epithet, propionicus (sic), has been corrected by Moore and Moore 1992.Publication:
