• Notes:
  • According to Stackebrandt et al. (1982), this species is a later heterotypic synonym of Nocardia cellulans Metcalfe and Brown 1957 (Approved Lists 1980). Publication: Stackebrandt E, Seiler H, Schleifer KH. Union of the genera Cellulomonas Bergey et al. and Oerskovia Prauser et al. in a redefined genus Cellulomonas. Zentralbl. Bakteriol. Parasitenkd. Infektionskr. Hyg. Abt. 1 Orig. 1982; C3:401-409.

  • Oerskovia xanthineolytica 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 Oerskovia.
  • The phylogenomic assignment score of this taxon is -0.19581 (N = 8).
  • The proposal to combine all five species under the name Cellulomonas cartae is not in accordance with the Bacteriological Code because the specific epithet cellulans in Nocardia cellulans Metcalf and Brown 1957 has priority over the specific epithet cartae in Cellulomonas cartae Stackebrandt and Kandler 1980 [Rules 38 and 42]. Publication: Stackebrandt E, Keddie RM. Genus Cellulomonas Bergey et al. 1923, 154, emend. mut. char. Clark 1952, 50AL.

  • Therefore, the name of the taxon under which they are united is Cellulomonas cellulans (Metcalf and Brown 1957) Stackebrandt and Keddie 1988, comb. nov. [2, 3]. Publication: Anonymous. Validation list no. 25. Validation of publication of new names and new combinations previously effectively published outside the IJSB. Int J Syst Bacteriol 1988; 38:220-222.
  • The full TRBA 466 classification is: risk group = 1, note = "ht+".
