[1] Cell wall teichoic acid composition is a chemical marker of the mycelium-forming nocardioides species and the proposal of nocardioides prauserii sp. nov / E. M. Tul’skaya, V. I. Krausova, E. Y. Gavrish et al. // 1st FEMS Congress of European Microbiologists. Ljubljana, Slovenia, (Abstract book), Ljubljana, June 29 – July 3, 2003. — Elsevier on behalf of the Federation of European Microbiological Soscieties Elsevier Science Publishers On Behalf Of The Federation Of European Microbilogical Societies, Amsterdam, Netherlands, 2003. — P. 357–357. The type strain N. luteus VKM Ac-1246T and six strains with white colonies assigned previously to the species N. albus exhibited from 63 to 74.2% DNA relatedness and contained identical the 1,5-poly(ribitol phosphate) teichoic acid, completely substituted at C4 by -D-galactopyranosil residues carrying a 4,6-pyruvate ketal group in R-configuration in the cell wall, while the type strain N. albus VKM Ac-805T possessed a poly(glycosylglycerol phosphate) polymer. Another strain, N. albus VKM Ac–806 (=DSM 43874), was found to distant from both N. albus and N. luteus genomically (nearly 50% DNA relatedness) and supposedly contained at least two polymers of different structure, teichoic acid closely related to teichoic acid from cell wall of N. luteus and the polymer containing rhamnose. On the basis of the data obtained, the new species Nocardioides prauseri sp. nov. is proposed, with the strain VKM Ac-806 (=DSM 43874 =ATCC 43083) as the type. Further, the species descriptions of N. albus and N. luteus are proposed to emend, with including of the cell wall teichoic acid composition and their structural components as the most important diagnostic characters of these species. Respectively, the species N. luteus harbors the strains characterized by white or yellow primary mycelium.
