Yeast extract is a nutrient source for preparing microbiological culture media. Yeast extract helps bacteria to grow by providing nitrogenous compounds, carbon, sulfur, trace nutrients, b-complex vitamins, and other growth factors for microorganisms.
IBI Scientific’s yeast extract is the water-soluble portion of autolyzed yeast. The autolysis is carefully controlled to preserve the naturally occurring B-complex vitamins. It is an excellent stimulator of bacterial growth and is used in culture media in place of, or in addition to, beef extract.
