Wheat straw for 2nd generation bioethanol production was pre-treated by means of steam explosion. During this procedure, many different inhibitors were formed. To enhance the final ethanol production, various strategies were tested to circumvent the inhibiting effects of these compounds. These strategies included washing the pre-treated straw and/or adaptation of different yeast strains to the inhibitors and/or on-site enzyme production. Standardised hydrolyses and fermentations were conducted. Adaption of yeasts had already been achieved and initial experiments showed promising findings concerning washing the pre-treated straw. Our results show that the inhibitors identified were quite different from those described in the literature. A comprehensive up to date concept for 2nd generation bioethanol production is presented in this project.
