Fermentation of Biomass Sugars to Ethanol Biomass sugars, produced in pretreatment and hydrolysis of biomass, can be fermented into ethanol through the use of genetically engineered microorganisms such as yeasts and bacteria. Conducting fuel cycle analysis of bioethanol is very important for determining its feasibility on an industry level, and its viability on an economic market level. Lignin Utilization Lignin is a substance in lignocellulsic material that provides rigidity and, together with cellulose, forms the woody cell walls of plants and the cementing material between them. It is used as a boiler fuel to provide heat and electricity for the ethanol production process. Developing the ability to process solids is one of the most vital accomplishments in this area of research.
Researchers have extensive experience at moving solids around within their equipment and processes.
They have developed a mini pilot system and a pilot plant that have unique capabilities for processing high-solid slurrys. Researchers involved in this area perform complex simulations that accurately project the economics of bioethanol production and determine the feasibility of building and operating a bioethanol plant. SSCF combines the saccharification and fermentation steps in one vessel to produce high yields of ethanol. The Alternative Fuels and Lubrication Technologies team within OHVT is working to optimize alternative fuel engines and engine systems. In addition, the team analyzes alternative fuel use, lubrication technologies, and the atmospheric reactions related to alternative fuel use.
