Key features
Applications
Nitrogen source for general use.
Industry
Fermentation, ingredients for culture media, manufacturing process.
Principles and uses
It is rich in proteins, peptides, amino acids, nucleotides, vitamins and trace elements, and low in endotoxin. Its nutrients promote the growth and metabolism of microorganisms and cells.
Yeast Extract Bioprocess Grade meets the requirements of high-end bio-fermentation such as genetically engineered pharmaceuticals, hyaluronic acids, vaccines, etc.
An important characteristic is the high performance, cost-effectiveness and consistency between different batches, which meet the requirements of high-end bio-fermentation, laboratory culture media and microbiology tests.
Widely used in large-scale industrial fermentation, such as amino acids, probiotics, starter cultures, organic acids, antibiotics, enzymes, vitamins and other bio-based products.
