Аннотация:The type strains of the species of the cluster "Streptomyces lavendulae" 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-1221(T) and S. polychromogenes VKM Ac-1207(T) synthesize mannan with different amounts of alpha -1,2- and alpha -1,3-substituted mannopyranose units and a small number of 1,3-poly(glycerolphosphate) chains. The cell walls of S. lavendulocolor VKM Ac-215(T) 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-1218(T) and S. flavotricini VKM Ac-1277(T) Contain the same poly(glucosyl-glycerolphosphate). The results presented in this paper are in accordance
