• Notes:
  • Nomenclatural type of the genus Flavimonas Holmes et al. 1987. Publication: Holmes B, Steigerwalt AG, Weaver RE, Brenner DJ. Chryseomonas luteola comb. nov. and Flavimonas oryzihabitans gen. nov., comb. nov., Pseudomonas-like species from human clinical specimens and formerly known, respectively, as groups Ve-1 and Ve-2. Int. J. Syst. Bacteriol. 1987; 37:245-250.
  • According to Lalucat et al. (2020), this species is an earlier heterotypic synonym of Pseudomonas psychrotolerans Hauser et al. 2004. Publication: Lalucat J, Mulet M, Gomila M, Garcia-Valdes E. Genomics in Bacterial Taxonomy: Impact on the Genus Pseudomonas. Genes (Basel) 2020; 11:0.
  • Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. List of changes in taxonomic opinion no. 35. Notification of changes in taxonomic opinion previously published outside the IJSEM. Int J Syst Evol Microbiol 2022; 72:5164.
  • Flavimonas oryzihabitans is the correct name 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 Flavimonas.
  • Re-evaluation of the original taxonomy as Pseudomonas oryzihabitans IJSB 47:251. Publication: Anzai Y, Kudo Y, Oyaizu H. The phylogeny of the genera Chryseomonas, Flavimonas, and Pseudomonas supports synonymy of these three genera. Int J Syst Bacteriol 1997; 47:249-251.
  • The level of similarity between the 16S rRNA sequence of the strain KS0036 L-1 AJ 2197 IAM 1568 JCM 2952 (the type strain of the species Pseudomonas oryzihabitans Kodama et al. 1985) and the 16S rRNA of the strain DSM 50071 ATCC 10145 [the type strain of the species Pseudomonas aeruginosa (Schroeter 1872) Migula 1900 (Approved Lists 1980)] is 93.9%. This result suggests that Flavimonas Holmes et al. 1987 is a later heterotypic synonym of Pseudomonas Migula 1894 (Approved Lists 1980) and that the name Pseudomonas oryzihabitans should be used for this species. Publication: Anzai Y, Kudo Y, Oyaizu H. The phylogeny of the genera Chryseomonas, Flavimonas, and Pseudomonas supports synonymy of these three genera. Int J Syst Bacteriol 1997; 47:249-251.
