In this flexible lab sequence, students convert cellulosic biomass sources, such as sawdust, straw, or cardboard into sugars and then ethanol. As biomass samples are pretreated, enzymatically digested, and fermented, students use glucose meters and ethanol probes to measure the key products of this chemical conversion. In the process, students can test predictions about which biomass sources and treatment methods will be most effective for producing ethanol. Instructional materials are available for download at the site and include student and instructor laboratory manuals; powerpoint slides and discussion guides.
