A novel type of teichoic acid from the cell wall of Bacillus subtilis VKM B-762.

The cell wall of Bacillus subtilis VKM B-762 contains, along with 1,5-poly[4-O-(2-acetamido-2-deoxy-β-D-glucopyranosyl)ribitol phosphate], a novel type of glycopolymer involving three types of inter-monomeric bonds in the repeating unit, viz., amide, glycosidic and phosphodiester: [See figure in text]. Such a structural pattern of natural glycopolymers has been hitherto unknown.

Cell wall teichoic acids of streptomycetes of the phenetic cluster 'Streptomyces fulvissimus'.

Structures of the anionic polymers of streptomycetes Streptomyces fulvissimus VKM Ac-994(T), Streptomyces longispororuber VKM Ac-1735(T), Streptomyces aureoveticillatus VKM Ac-48(T) and Streptomyces spectabilis INA 00606 belonging to the phenetic cluster 'S. fulvissimus' were investigated by chemical and NMR spectroscopic methods.
