Ethanol Production from Saccharum Spontanum Biomass Native to Nepal Using Bioelectrochemical Cell

Abstract

Bioethanol can be used as an octane enhancer and alternative replacement to blend with petroleum fuels. Using an electrochemical cell for the production of bioethanol facilitates the enhancement in ethanol production exploiting the electrochemical redox reactions occuring inside the cell. The externally supplied voltage is used to drive the chemical reactions to generate the metabolite, i.e; ethanol. A microbial electrochemical cell was designed with porous carbon fiber coated with neutral red as cathode and platinum wire coated with fine platinum as anode. Saccharum spontanum biomass pretreated with hot water at 100 °C for 2 hours followed by acid hydrolysis was neutralized and used for production of ethanol by Saccharomyces cereviseae in electrochemical cell. A total supply of 4V was found to be best for maximum ethanol production in 300 ml fermentation volume. Key words: ethanol, microbial electrochemical cell, voltage.
