[Structure of cell-wall teichoic acids in Streptomyces roseoflavus var. roseofungini and its Nocardia-like variant].
The structure of teichoic acids was studied in the cell walls of Streptomyces roseoflavus var. roseofungini 1128 and its Nocardia-like variant 1-68 differing from the parent strain in the absence of a spore-forming aerial mycelium as well as by the fragmentation of hyphae in the substrate mycelium. The teichoic acids of the both cultures consist of a 1,3-poly(glycerophosphate) chain containing 11-13 glycerolphosphate residues which have glucosamynl units and lysine groups bound through an ester bond. These teichoic acids contain no O-acetyl groups, in contrast to the glyceroteichoic acids of actinomycetes studied earlier. The teichoic acid from the cell wall of the variant has less lysine and glucosamine then the parent strain. The content of teichoic acid in the cell wall of the parent culture is 4.5 times greater than in the wall of the variant.
