• Emendations:
  • Yabuuchi et al. 1998 Yabuuchi E, Kawamura Y, Kosako Y, Ezaki T. Emendation of genus Achromobacter and Achromobacter xylosoxidans (Yabuuchi and Yano) and proposal of Achromobacter ruhlandii (Packer and Vishniac) comb. nov., Achromobacter piechaudii (Kiredjian et al.) comb. nov., and Achromobacter xylosoxidans subsp. denitrificans (Ruger and Tan) comb. nov. Microbiol Immunol 1998; 42:429-438. Anonymous. Validation list no. 67. Validation of publication of new names and new combinations previously effectively published outside the IJSB. Int J Syst Bacteriol 1998; 48:1083-1084.
    Notes:
    • Emendation accompanied by the proposal of 2 new species in the genus.
    • The results of phylogenetic analyses of 16S rRNA nucleotide sequences and a difference of more 10% in GC contents of DNA demonstrate that Achromobacter xylosoxidans (ex Yabuuchi and Ohyama 1971) Yabuuchi and Yano 1981, the type species of the genus Achromobacter, and Alcaligenes faecalis Castellani and Chalmers 1919 (Approved Lists 1980), the type species of the genus Alcaligenes, belong to the 2 distinct genera Achromobacter Yabuuchi and Yano 1981 emend. Yabuuchi et al. 1998 and Alcaligenes Castellani and Chalmers 1919 (Approved Lists 1980), respectively.

• Notes:
  • The type species of this genus has alternatively been placed in the genus Alcaligenes Castellani and Chalmers 1919 (Approved Lists 1980). Publication: Kiredjian M, Holmes B, Kersters K, Guilvout I, De Ley J. Alcaligenes piechaudii, a new species from human clinical specimens and the environment. Int. J. Syst. Bacteriol. 1986; 36:282-287.
  • "Achromobacter" Bergey et al. 1923, type species "Achromobacter liquefaciens" (Eisenberg 1891) Bergey et al. 1923, was not included in the Approved Lists 1980, because the lack of an identifiable culture of "Achromobacter liquefaciens".
