High-temperature Fermentation Technology for Low-cost Bioethanol

Abstract

Considering its advantages including reduction of cooling cost and saving water during the fermentation process, which consequently cut down the total running cost, high-temperature fermentation with thermotolerant microbes is expected to be one of next-generation fermentation technologies. We focused on the establishment of high-temperature fermentation technology for ethanol production from biomass in Thailand, for which thermotolerant microbes suitable for various types of biomass were selected and advanced fermentation processes including a temperature-uncontrolled fermentation and a simultaneous fermentation and distillation under a low pressure were investigated.
