[Study of PLi genes action on the cell wall structure of "Saccharomyces cerevisiae" Hansen (author's transl)].

A study of the composition of cell walls extracted from a wild strain and three mutant strains "smooth colony" of Saccharomyces cerevisiae had been done. It points out differences in the mannose/glucose ratio and in the concentration of some other components of the cell wall in the mutant strains. The immunological study of the cell wall shows that "smooth colonies" mutants and wild strains differs in their mannoproteins.
