• Notes:
  • ❗ Peptococcus heliotrinreducens 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 Peptococcus.

  • 🧍 The specific epithet heliotrinreducens (sic) has been corrected in the new combination Slackia heliotrinireducens [see, Slackia heliotrinireducens corrig. (Lanigan 1983) Wade et al. 1999, comb. nov.]. However the name "Peptococcus heliotrinireducens" corrig. has never been formally proposed before December 14, 2000 [date of publication of the amended Rule 61; see Int. J. Syst. Evol. Microbiol., 2000, 50, page 2239, column (2)]. Consequently, in the "List of Prokaryotic names with Standing in Nomenclature", the epithet heliotrinreducens (sic) has been maintained for Peptococcus heliotrinreducens.
