Enriched medium
Oct 17, 2019
All microorganisms, including yeast, need the following basic components for growth and development:
- A carbon source, generally coming from beet or cane molasses
- A nitrogen source such as ammonium sulphate or phosphate
- Minerals and traces elements (P, K, Ca, Na, Fe, Cu, Co)
- Vitamins (biotin, pantothenate, thiamine, pyridoxine, etc.)
- The growth medium can be enriched with one or several of these components. Often, vitamins, minerals or trace elements will be added in larger amounts than what is required for the optimal yeast growth. Still, these components will be absorbed and stored in the yeast cell compartments. Enriched yeast can be used in normal nutrition applications or for the production of encapsulated supplements.
