Yeast peptone is a premium biological nitrogen source, meticulously derived from high-protein bread yeast through an advanced process that includes autolysis, enzymatic hydrolysis, multi-stage separation, vacuum concentration, and spray drying. This production method facilitates the self-decomposition of yeast cells and targeted enzymatic breakdown, transforming large proteins into easily absorbable components such as small peptides and free amino acids, From the fermentation perspective, yeast peptone is not only rich in proteins, peptides, and amino acids but also abundant in nucleotides, B vitamins, biotin, and various growth factors. These essential nutrients provide a comprehensive and balanced support system for microorganisms, effectively enhancing cell proliferation and metabolic processes, In terms of application, yeast peptone is extensively utilized within microbial fermentation, biological preparations, and industrial fermentation sectors. When used in conjunction with yeast extract and other medium components, it significantly boosts microbial growth, enhances metabolic activity, and promotes the synthesis of target products, leading to improved fermentation efficiency and higher product yields. As a leading supplier from China, our factory guarantees the quality and consistency of our yeast peptone, making it an essential ingredient for diverse fermentation applications
