Nocardiopsis tropica sp, nov., Nocardiopsis trehalosi sp nov., nom. rev. and Nocardiopsis dassonvillei subsp, albirubida subsp nov., comb. nov.

Sixteen strains isolated from different soils and marine sediments and 'Nocardiopsis trehalosi' VKM Ac-942(T) were subjected: to taxonomic analyses. The morphological and chemotaxonomic characteristics of the strains matched those described for members of the Nocardiopsis. Based on 16S rDNA sequence analysis, DNA-DNA hybridization values and phenotypic characteristics, including the composition of menaquinones and cell wall teichoic acids, two new species are proposed, Nocardiopsis tropica sp. nov. (type strain VKM Ac-1457(T)) and Nocardiopsis trehalosi sp, nov., nom, rev. (type strain VKM Ac-942(T) = JCM 3357(T) = NRRL 12026(T)). Nocardiopsis dassonvillei VKM Ac-1882(T) (formerly Nocardiopsis albirubida) differs from other strains of this species by the presence of MK-10 as the major menaquinone, cell well teichoic acid structure, and numerical analysis based on 115 growth and physiological characteristics. The strain is reclassified as the subspecies Nocardiopsis dassonvillei subsp, albirubida, with VKM Ac- 1882(T) (= DSM 43465(T) = ATCC 23612(T) = ISP 5465(T)) designated the type.
