Precise analysis of Yeast and Monitoring of Cell Growth

Yeast is a type of single-celled fungus with many attractive features that are widely used in the brewing industry, commercial production, environmental protection, and scientific research. Yeast has been commonly used in brewing and bread baking from a very long time ago, and many yeasts are used to produce a variety of feeds and industrial nutrients such as Single Cell Protein (SCP).
