YEAST NUTRIENTS FOR THE CULTURE MEDIUM OF FERMENTATION YEAST

摘要

Yeast nutrients are provided to effectively improve the glutathione productivity and yield of Saccharomyces cerevisiae FF-8(deposition no. KACC93023P) by optimizing supplying sources and supplying amounts of carbon, nitrogen, salt and amino acid. A yeast nutrient for a culture medium of fermentation yeast comprises 3.0 wt.% of glucose as a carbon source, 3.0 wt.% of a yeast extract as a nitrogen source, 0.06 wt.% of KH2PO4 as a salt source and 0.06 wt.% of L-cysteine as an amino acid source regarding the total weight of the culture medium.
