Fermentation-Promoting Peptides Enhance Yeast Robustness during Very High Gravity Fermentation by Reinforcing Antioxidant Defenses and Modulating Intracellular Metabolism.
Very high gravity (VHG) fermentation imposes multiple stresses that impair yeast performance. The effects of fermentation-promoting peptides and their corresponding amino acids on yeast physiology and metabolism were systematically examined under VHG conditions. Peptide supplementation, particularly LL (Leu-Leu), LLL (...
