An effective automated glucose sensor for fermentation monitoring and control.
An industrial glucose analyser was partnered to an automated injection system to evaluate glucose in the culture medium of a bioreactor. This sensor has been validated on continuous cultures ofSchizosaccharomyces pombe and continuous and fed-batch cultures ofSaccharomyces cerevisiae. In addition to the advantage of a more accurate process monitoring, the main interest of this sensor deals with the control of the substrate concentration to a prespecified reference signal. Several experiments have been carried out first to validate the sensor, then to control the process evolution.
