Abstract
The cost and availability of petroleum and natural gas has generated interest in bioconversion processes that utilize renewable biomass resources for the production of fuels and chemical feedstocks. The bioconversion of biomass to ethanol via anaerobic fermentations offers the promise of renewable liquid fuel and renewable chemical feedstocks. The purpose of this presentation is to review some of the recent studies in my laboratory on thermophilic ethanol fermentations. The emphasis of this review will be on understanding fundamental aspects of the physiology and biochemistry of thermophilic anaerobes that may be of applied interest in developing bioconversion technology for alcohol production. Most of the findings summarized here represent material published elsewhere (1–22).
