Yeast extracts

During yeast extract production, the endogenous natural enzymes breakdown the yeast components into smaller molecular weight compounds such as peptides and amino acids. The process is called autolysis.

FNI 100 ag, has been selected to be effective for protein expression by E.coli with low acetate production.

Yeast Autolysates

Autolyzed yeast is produced by inactivating the natural enzymes endogenous in yeast cream and then by adding enzymes to the soluble fraction. After the hydrolysis, the yeast slurry is simply dried without separation of the cell wall material. Therefore, contrary to yeast peptones, yeast autolyzates contain the soluble proteinaceous compounds as well as the cell wall material.

Lallemand autolyzed yeast has been shown to support the growth of Lactobacillus and other bacteria. Products are also suggested for second metabolites production. The yeast cell material provides complex ingredients for long lasting release of components (see graph).

FNI 100 ag, has been shown to be effective for many non-fastidious microbial cultures.
