• Emendations:
  • Stackebrandt et al. 2002 Stackebrandt E, Breymann S, Steiner U, Prauser H, Weiss N, Schumann P. Re-evaluation of the status of the genus Oerskovia, reclassification of Promicromonospora enterophila (Jager et al. 1983) as Oerskovia enterophila comb. nov. and description of Oerskovia jenensis sp. nov. and Oerskovia paurometabola sp. nov. Int J Syst Evol Microbiol 2002; 52:1105-1111. Anonymous. Notification list. Notification that new names and new combinations have appeared in volume 52, part 4 of the IJSEM. Int J Syst Evol Microbiol 2002; 52:1439-1440.
    Notes:
    • ⊕ Emendation accompanied by the proposal of 3 new species in the genus.
    • 🧍 The 16S rDNA analysis, DNA-DNA reassociation, riboprinting, peptidoglycan analysis and determination of phenotypic properties of various strain of Cellulomonas turbata (Erikson 1954) Stackebrandt et al. 1983 [basonym: Oerskovia turbata (Erikson 1954) Prauser et al. 1970 (Approved Lists 1980)] reveal that they form a cluster that can be distinguished unambiguously from other Cellulomonas species by morphology, amino acid composition of the cell wall and 16 rDNA signatures. As a result of this polyphasic study, it appears taxonomically reasonable to re-establish the genus Oerskovia.
