Computer Controlled System for On-line Monitoring of a Fermentation Process
A computer controlled laboratory system is set up in order to study lactic acid fermentation kinetics using Streptococcus cremoris. The system consists of a laboratory fermentor with on-line Flow Injection Analysers for glucose, lactic acid, protein and optical density. Sample withdrawal and operation of the analytical system is controlled by a PC, which also performs data acquisition, calibration and calculation. The layout of the system is shown in Figure 1. The system is well suited for studies of lactic acid fermentation at dynamic as well as at steady-state conditions. The overall goal of the investigation is to set up a simple structured mathematical model that describes growth and product formation during both steady-state and dynamic conditions.
