• Notes:
  • 🧕 Cavalier-Smith (1981) assigned this genus to the subkingdom "Eubacteria" Cavalier-Smith 1981. Publication: Cavalier-Smith T. Eukaryote kingdoms: seven or nine? Biosystems 1981; 14:461-481.
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Streptomyces Waksman and Henrici 1943 (Approved Lists 1980). Publication: Pridham TG. New names and new combinations in the order Actinomycetales Buchanan 1917. Bulletin of the United States Department of Agriculture 1970; 1424:1-55.
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Cbainia"; "Chaillia"; "Ciminia"; "Clzainia"; "Ohainia".
  • ❗ Chainia is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: NRRL: 23; IFO: 22; JCM: 22; NBRC: 22; CBS: 19; DSM: 18; ATCC: 14; BCRC: 11; CCRC: 11; VKM: 8.
  • 🧍 Pittman et al. (1991) suggested the abbreviation "CHNA" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM. Codes and abbreviations for approved of effectively published names of genera of bacteria published from January 1980 to December 1990. Int J Syst Bacteriol 1991; 41:571-579.
  • 🧍 According to Goodfellow et al., the genus Chainia Thirumalachar 1955 (Approved Lists 1980) is a later synonym of the genus Streptomyces Waksman and Henrici 1943 (Approved Lists 1980).
