F.G. YEAST EXTRACT
CAT Nº:1721
Ingredients (Extracts)
DESCRIPTION
This Yeast extract is made from high quality baker’s yeast extract through special enzymatic technology and strict quality
assurance system so that the nutrients could be kept better in yeast extract. Furthermore, the macromolecule
substances which is hard to assimilate by microorganisms have been removed well. The 50 g/L water solution of yeast
extract is bright color, clear and clarity in room temperature and pre or post autoclaving process, which is good for high
efficient assimilation of nutrients by microorganisms and beneficial for downstream process/clean fermentation.
Completely degradated nutrients promote the growth and metabolism of microorganisms and cells.
It is rich in proteins, peptides, amino acids, nucleotides, vitamins, trace elements and low endotoxin .
The dehydrated Yeast Extract should be homogeneous, free flowing and light beige to yellow in color. If there are any
changes physically, discard the product.
Application
Could well meet the requirements of high-end bio-fermentation such as genetically engineered
pharmaceuticals，hyaluronic acids, vaccines, etc. The most important thing it is a kind of high performance, cost
effective, consistent between different batches which meet the requirements of high-end bio-fermentation factory.
Laboratory culture media and microbiology test. Widely used in large scale industry fermentation, such as Amino acids,
Probiotics, Starter culture, Organic acids, Antibiotics, Enzymes, Vitamins and other bio-based products.
