Abstract
The type strains of the species of the cluster "Streptomyces lavendulae" wi th a low level of DNA-DNA relatedness were found to contain different cell- wall carbohydrate polymers, whereas the species of this cluster with a leve l of DNA-DNA relatedness of about 60% contain similar or identical carbohyd rate polymers. The type strains Streptomyces katrae VKM Ac-1221(T) and S. p olychromogenes VKM Ac-1207(T) synthesize mannan with different amounts of a lpha -1,2- and alpha -1,3-substituted mannopyranose units and a small numbe r of 1,3-poly(glycerolphosphate) chains. The cell walls of S. lavendulocolo r VKM Ac-215(T) and Streptomyces sp. VKM Ac-2117 were found to contain a hi therto unknown teichuronic acid, whose repeating unit is a disaccharide con sisting of diaminomannuronic acid and N-acetylgalactosamine: --> 4)-beta -D -ManpNAc3NAcA-(1 --> 3)-alpha -D-GalpNAc-(1 -->. In addition, the cell wall s of these two streptomycetes contain beta -glucosylated 1,5-poly(ribitol p hosphate). The cell walls of S. virginiae VKM Ac-1218(T) and S. flavotricin i VKM Ac-1277(T) Contain the same poly(glucosyl-glycerolphosphate). The res ults presented in this paper are in accordance with the DNA-DNA relatedness data and indicate a taxonomic significance of the structure of the cell-wa ll polysaccharides for the delineation of phenetically related Streptomyces species.
