Glutathione production by immobilized Saccharomyces cerevisiae cells containing an ATP regeneration system

Summary Whole cells of Saccharomyces cerevisiae were immobilized in polyacrylamide gel. Consuming glucose, the immobilized cells produced glutathione from its constituent amino acids, and glutathione produced was excreted out of the gels. The conditions for immobilization of the yeast cells and for glutathione production were studied. Based on these data, the properties and the feasibility of the glycolytic pathway as an ATP regeneration system were discussed in reference to glutathione production.
