Description

Bacto Yeast Extracts are concentrates of the water-soluble portion of autolyzed Saccharomyces cerevisiae cells. They are derived from primary grown baker’s yeast. These animal origin-free products are suitable for use as multi-functional nutritional supplements in mammalian cell culture, microbial fermentation, and insect cell culture applications. Yeast extract provides essential water-soluble vitamins, amino acids, peptides, and carbohydrates to any medium formulation.

Bacto Yeast Extract is one of the most complete and versatile fermentation supplements available. It is an important ingredient for the microbiological assay of vitamins.
