Further Study on Yeast - DCFC Device Development (Part Two)

The development of a system consisting of a device based on a fuel cell for ethanol, coupled to yeast cells (Saccaromyces Cerevisiae), has been completed. Through the use of a potentiostat, connected to a PC, the optimization of the system was then carried out by studying the type of yeast to be used and by monitoring the power curves obtained. The device was then used for the determination of glucose in test solutions and for the detection of the “pool” of carbohydrates in commercial soft drinks.
