[Methodical approaches to isolation of teichoic acids from native cells of lactic acid bacteria probiotic strains].

Teichoic acids of lactic acid bacteria probiotic strains have been obtained by extraction from native cells, followed by purification of extracts using ion exchange chromatography. Selected fractions contained high concentrations of phosphorus and did not contain nucleic acids. The content of teichoic acid depended on the species and strain specificity. Heterogeneity of the studied biomolecules was revealed.
