Abstract

Hemicellulose hydrolysates of the agricultural residues bagasse, corn stover, and corn hulls plus fibers were readily fermented to ethanol by recombinantEscherichia coli strain KO11. Corn steep liquor and crude yeast autolysate served as excellent nutrients. Fermentations were substantially complete within 48 h, often achieving over 40 g ethanol L−1. Ethanol yields ranged from 86% to over 100% of the maximum theoretical yield (0.51 g ethanol g sugar−1.
