Product Introduction‌

High-nucleic acid yeast extract (abbreviated as YE) is a pure natural product refined through modern biotechnology, including enzymatic hydrolysis, separation, and concentration. It is derived from high-nucleic acid yeast fermented using molasses and starch sugar as raw materials.

Ingredients:‌ Edible yeast, sugarcane molasses, starch sugar, etc.

Appearance:‌ Light yellow or yellowish-brown powder.

Nutritional Components‌

High-nucleic acid yeast extract is rich in ribonucleic acid, amino acids, peptides, vitamins, and trace elements. Nucleic acid serves as a critical genetic material foundation for microbial growth and reproduction, providing essential nucleic acid precursors for synthesizing genetic material and proteins, thereby promoting rapid microbial proliferation. For example, in cultures of Escherichia coli or cytidine-producing strains, it significantly enhances reproduction speed and metabolite yield. Abundant amino acids act as vital raw materials for microbial protein synthesis, supplying nitrogen and carbon sources to support growth and metabolic demands. Additionally, it contains B vitamins and trace elements such as iron, zinc, and magnesium, which participate in diverse metabolic reactions within microorganisms.

Product Benefits‌

Accelerate Growth Speed:‌ The nucleic acids and amino acids in high-nucleic acid yeast extract provide microorganisms with comprehensive and easily absorbable nutrition, shortening the growth lag phase and enabling faster entry into logarithmic growth. This accelerates growth speed and improves fermentation efficiency. For instance, in guanylic acid fermentation, using this extract as a medium component allows yeast to reach maximum growth rates more quickly, reducing fermentation cycle time.

Increase Fermentation Product Yield:‌ By providing optimal nutritional conditions, it enables microorganisms to engage more fully in metabolic activities, thereby enhancing the yield and quality of fermentation products. In antibiotic and amino acid fermentation, adding this extract promotes the growth of actinomycetes and other antibiotic-producing microorganisms, increasing antibiotic production.

Enhance Microbial Vitality:‌ It helps maintain normal physiological functions and metabolic activity in microbial cells, improving resistance to environmental stressors such as temperature and pH fluctuations. This ensures microorganisms maintain high vitality during fermentation, reducing growth stagnation or death caused by environmental changes.

Improve Medium Flavor and Taste:‌ In food fermentation media, nucleic acids undergo enzymatic hydrolysis to produce flavor nucleotides (e.g., inosinic acid, guanylic acid, adenylic acid), imparting a unique umami and rich flavor to the medium. This distinctive flavor enhances the taste and mouthfeel of fermented foods, boosting market competitiveness. For example, in酱油 (soy sauce),醋 (vinegar), and fermented beverages, it increases umami and richness, improving overall quality.

Product Advantages‌

Pure Natural Product:‌ Produced using modern biotechnology with edible yeast as the raw material, refined through autolysis and enzymatic hydrolysis. It is a pure natural nutrient, free from harmful chemicals, aligning with green and eco-friendly production principles, and safe for use in microbial cultures.

Stable and Reliable Quality:‌ The production process strictly follows standardized procedures, with rigorous requirements for raw material screening, process parameter control, and quality testing. This ensures consistent nutrient content and quality across batches, providing a stable nutritional environment for microbial cultivation and guaranteeing fermentation process stability and repeatability.

Excellent Solubility and Compatibility:‌ Exhibits strong water solubility, rapidly dissolving in media to uniformly supply nutrients. It also demonstrates good compatibility with other medium components, avoiding chemical reactions or precipitation. It can be used with various carbon sources, nitrogen sources, and inorganic salts to meet diverse microbial cultivation needs.
