Modification of the Composition and Structure of the Yeast Cell Wall by Culture in the Presence of Sulfur Amino Acids

摘要: Growth of Candida utilis and Saccharomyces cerevisiae in a medium supplemented with sulfur amino acids led to synthesis accumulation S-adenosylmethionine, accompanied by reduction the cell yield, an increased sensitivity wall snail gut enzymes (Helix pomatia), as judged spheroplast formation, modification chemical composition both intact cells their isolated walls. Walls cultures C. were three times sensitive enzymatic digestion walls from nonsupplemented cultures. In contrast utilis, S. digested slightly more rapidly purified extract than those Chemical modifications are interpreted explain ease which acid-supplemented converted spheroplasts.
