Model-based quality control of the baker's yeast Saccharomyces cerevisiae.

ABSTRACT

This paper deals with the optimal control of storage stability for compressed baker's yeast by minimizing the fraction of budding cells (FBC) based on a metabolic and cell cyclic model system for Saccharomyces cerevisiae. Three experiments of quality control were successfully carried out. The experimental data revealed that under optimal operation conditions, the final FBC-values approached the theoretical minimum and that storage stability was enhanced.
