Technical Abstract: Economic studies on bioconversion of corn to butanol have demonstrated that substrate cost affects butanol price most. Hence, to produce butanol cost competitively, more economical substrates should be used. Additionally, process technologies, such as reactor designs and energy efficient product recovery systems, play important roles in producing this biofuel cost competitively. For these studies, we used lignocellulosic residues such as wheat straw (WS), corn stover (CS), barley straw (BS), and switchgrass (SW) and produced butanol in batch and fed-batch fermentations. In these processes, we integrated (combined) hydrolysis, fermentation, and product recovery in a single step. This presentation will include recent developments in butanol fermentation and process technology.
