Abstract

The application of a Fresnel-based fiber sensor on real-time monitoring of the fermentation process in bioethanol production is reported. The fiber was placed inside the bioreactor, and experiments were conducted by using glucose solution and sugarcane syrup as substrates for fermentation. When the sugar is completely consumed, there is no production of ethanol, causing the sample concentration to become constant, as well as the reflected light intensity. Therefore, the sensor can be used to predict the ideal moment to terminate the process. The results were confirmed by additional laboratory analysis, making this an alternative technology for optimization of bioethanol production.
