This report describes the building of a simulator for prediction of the dissolved oxygen concentration, the oxygen transfer rate and the concentration of carbon dioxide in a fermentation process. The steady state models were made using the linguistic equations method. The dynamic models were made using Simulink® toolbox in the Matlab®.

At the beginning, some basics about fermentation and microbiological reactions are stated. In the third chapter the modelling methods are presented. The modelling experiments are presented in chapter four and after that the results are stated. Chapter six includes discussion about the results and the conclusions. The simulation results were good.
