Abstract
Phylogenetic analysis of Promicromonospora enterophila indicates that this taxon clusters with Cellulomonas species, adjacent to Cellulomonas turbata (basonym Oerskovia turbata). 16S rDNA analysis, DNA--DNA reassociation, riboprinting, peptidoglycan analysis and determination of phenotypic properties of various strains of P. enterophila and C. turbata 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 16S rDNA signatures. As a result of this polyphasic study, it appears taxonomically reasonable to re-establish the genus Oerskovia for C. turbata and to reclassify P. enterophila as Oerskovia enterophila comb. nov.; two novel species, Oerskovia jenensis sp. nov. (type strain DSM 46000(T)=CIP 100330(T)) and Oerskovia paurometabola sp. nov. (type strain DSM 14281(T)=LMG 20385(T)), are also proposed.
