Abstract
The teichoic acids are widely distributed among actinomycetes. The widespread occurrence of teichoic acids in Gram-positive bacteria indicates undoubtedly the importance of their functions in the life of these cells. There are numerous variations in teichoic acid structures and especially in actinomycetes cells. About 100 different actinomycete cultures have been investigated and have established that their teichoic acids belong to two types: (1) glycerol phosphate and (2) ribitol phosphate polymers. Among the teichoic acids of actinomycetes, glycerol teichoic acids with 1,3-type of poly(glycerol phosphate) chain are of very common occurrence in cell walls. These polymers vary by their glycosyl substituents, 0-acyl residues and their amount, and also by the type of phosphodiester linkages between monomeric units.
