Adaptive Control of Continuous Fermentation with Immobilized Yeasts Saccharomyces Cerevisiae BO 213

摘要

In this paper, a new approach for adaptive linearizing control of continuous fermentations with immobilized yeasts Saccharomyces cerevisiae BO 213 was proposed. Three fermentations with three different procedures of cells immobilization were investigated. The switching from batch to continuous mode of cultivation was realized automatically in time when the ethanol production rate reaches its maximal value. This information was received by software sensor of ethanol production rate. The proposed control algorithm stabilizes the concentration of ethanol in the culture medium at value corresponding to maximal ethanol production rate. The simulation results are promising and could be verified in laboratory conditions.
