The conversion of existing agricultural and forestry products and waste into biofuels or other value-added products is of significant interest today - for first generation and advanced biofuel plants, municipal wastewater treatment plants, industrial food and beverage processors, pulp and paper mills, and/or cogeneration facilities. Converting lignocellulosic biomass, material like wood and grass, into useful fuels and chemicals is an important step in reducing our reliance on petroleum, without competing with the food supply. The bio-chemical conversion approach to lignocellulosic biofuels involves first breaking down the substances that make up biomass into their chemical constituents. Next, microbes are used to ferment useful chemicals that can be separated and used as a fuel or chemical precursor to other valuable products. The first half of this course will focus on the structure of lignocellulosic biomass and methods to break it down. The second half will focus on methods for producing useful products via fermentation and anaerobic digestion.
