As. Shashkov et al., The carbohydrate-containing cell-wall polymers of certain species from thecluster "Streptomyces lavendulae", MICROBIOLOG, 70(4), 2001, pp. 413-421
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.
