Yeast peptone is a premium biological nitrogen source derived from high-protein bread yeast through an advanced process involving autolysis, enzymatic hydrolysis, multi-stage separation, vacuum concentration, and spray drying. This method allows yeast cells to self-decompose and undergo targeted enzymatic breakdown, transforming macromolecular proteins into easily absorbable small peptides, free amino acids, and other beneficial components, Rich in proteins, peptides, and amino acids, yeast peptone also boasts an abundance of nucleotides, B vitamins, biotin, and a variety of growth factors. These essential nutrients are vital for supporting microbial growth, cell proliferation, and physiological metabolism, As a leading product from China, yeast peptone is extensively utilized across numerous industries, including microbial fermentation, biological preparations, and industrial fermentation. When used in combination with yeast extract and other medium components, it significantly enhances microbial growth, increases metabolic activity, and boosts the synthesis of target products. This results in improved fermentation efficiency and higher product yields, making it a preferred choice among suppliers and factories looking to optimize their production processes
