• Notes:
  • Regarded as junior synonym of Serratia proteamaculans(IJSB 28:508) but later revised (Curr. Microbiol. 7:71, 1982); request for conservation denied IJSB 36:577. Publication: Grimont PAD, Grimont F, Starr MP. Serratia proteamaculans (Paine and Stansfield) comb. nov., a senior heterotypic synonym of Serratia liquefaciens (Grimes and Hennerty) Bascomb et al. Int. J. Syst. Bacteriol. 1978; 28:503-510.
  • This name was subject to a comment on a Request for an Opinion. Publication: Grimont PAD, Grimont F, Starr MP. Comment on the Request to the Judicial Commission to conserve the specific epithet liquefaciens over the specific epithet proteamaculans in the name of the organism currently known as Serratia liquefaciens. Int. J. Syst. Bacteriol. 1981; 31:211-212.
  • In the "Indexes of the Bacterial and Yeast Nomenclatural Changes", Moore and Moore [7, 8] write "Serratia liquefaciens (Grimes and Hennerty 1931) Bascomb et al. 1971 (AL) = Serratia proteamaculans (Paine and Stansfield 1919) Grimont et al. 1978 (AL)". However, Serratia liquefaciens and Serratia proteamaculans are distinct species. Publication: Holmes B.

  • On the Approved Lists of Bacterial Names, this nomenclatural name is incorrectly cited as Serratia liquefaciens (Grimes and Hennerty 1961[sic]) Bascomb et al. 1971.

Bacteriol. 1984; 34:508-511.
  • The full TRBA 466 classification is: risk group = 2, note = "n".
