Enzyme thermistor

Enzyme thermistors have a great potential for use as biosensors in fermentation and other process control systems. The thermistors are based on the measurement of the heat of enzymic reactions and can be used for offline and online analysis. They can be used to measure any product which reacts enzymically with a specific enzyme liberating heat which is converted in an appropriate electrical signal. A single system may be useful for monitoring various fermentations or other processes simultaneously for a given process parameter. Alternatively a set of in parallel systems can be used to monitor several different parameters. Interface electronics and software for improving the system performance and integration can be used. The advantages of the enzyme thermistor are its low cost and its specificity for the required analysis due to the enzymic reaction which is used.
