Yeast Extract, Ultrafiltered Granulated Cell Culture Tested

Yeast extract is obtained by controlled autolysis (self-digestion) of selected strain of yeast Saccharomyces. This water-soluble fraction of the autolysis process is rich in B complex vitamins and serves as an excellent nitrogen source. It is also rich in amino acids, peptides, purine and pyrimidine bases and growth factors. Ultra-fitration improves solubility and filterability. Since yeast extract is obtained from non-animal sources, it can be used as nutritional supplement in animal-free mammalian and insect cell culture media formulations.
