title: [The carbohydrate-containing cell wall polymers of some species from the cluster "Streptomyces lavendulae"].
abstract: The type strains of the cluster "Streptomyces lavendulae" species with a low level of DNA-DNA relatedness were found to contain different cell-wall carbohydrate polymers, whereas the species of this cluster with a level of DNA-DNA relatedness of about 60% contain similar or identical carbohydrate polymers. The type strains Streptomyces katrae VKM Ac-1220T and S. polychromogenes VKM Ac-1207T synthesize mannan with different amounts of alpha-1,2- and alpha-1,3-substituted mannopyranose units and a small number of 1,3-poly(glycerophosphate) chains. The cell walls of S. lavendulocolor VKM Ac-215T and Streptomyces sp. VKM Ac-2117 were found to contain a hitherto unknown teichuronic acid, whose repeating unit is a disaccharide consisting of diaminomannuronic acid and N-acetylgalactosamine:-->4)-beta-D-ManpNAc3NAcA-(1-->3)-alpha-D- GalpNAc-(1-->. In addition, the cell walls of these two streptomycetes contain beta-glucosylated 1,5-poly(ribitol phosphate). The cell walls of S. virginiae VKM Ac-1218T and S. flavotricini VKM Ac-1277T contain the same poly(glucosyl-glycerophosphate). The results presented in this paper are in accordance with the DNA-DNA relatedness data published earlier and indicate a taxonomic significance of the structure of the cell-wall polysaccharides for the delineation of pheneticall/related Streptomyces species.
