Real time monitoring of alcoholic fermentation with low-cost amperometric biosensors

► Development of screen-printed biosensors for glucose, fructose and ethanol. ► Application of the biosensors to the monitoring of alcoholic fermentations. ► Evaluation of the fermentation profiles obtained using two different yeast strains. ► Highlighting of the differences in metabolic behaviour of the two strains. ► Biosensor data in good agreement with spectrophotometric analyses.
