• Notes:
  • ❗ Bacillus subtilis subsp. inaquosorum is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Bacillus subtilis within a separate genus Bacillus.
