Cell wall teichoic acids of streptomycetes of the phenetic cluster ‘Streptomyces fulvissimus’

Cell walls of other streptomycetes of the phenocluster under study contain 1,3-poly(glycerol phosphates) with glucosamine as a glycosyl substituent at O-2 of the glycerol phosphate units and l-glutamic acid and lysine as O-2 acyl substituents. Not all amino sugar residues in the polymers of these strains are N-acetylated, and the content of the glucosamine and lysine residues in the polymers of different strains is not the same. Despite certain quantitative differences in the structures of the polymers, one may consider streptomycetes of the phenocluster ‘S. fulvissimus’ as closely related microorganisms, the details of the structures serving as additional criteria for the determination of the species status of a strain under study.
