  • 😩 Deposits incorrectly indicated in some sources as representing the type strain of this taxon: DSM 14382; MTCC 3702.
  • ❗ Micrococcus roseus 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 Micrococcus.
