<I>E. coli</I> for Three Fuels (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption For the three fuels E. coli engineered at JBEI, cellulose and hemicellulose are hydrolyzed by cellulase and hemicellulose enzymes (blue) into oligosaccharides, which are further hydrolyzed by β-glucosidase enzymes (red) into monosaccharides that can be metabolized into biofuels via metabolic pathways.
