  • 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.

    Notes:
    • 🧍 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 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 for Cellulomonas turbata.
