Butamax recently secured another patent 8,273,558 (‘558 patent). The innovative ‘558 patent technology provides a path to commercial production volumes of biobutanol. Butamax has specifically designed its microorganism to be cost-effective for all markets, but particularly for biofuel blending. While unmodified yeast may produce trace amounts of isobutanol via a different pathway than Butamax’s inventions, these unmodified yeasts only express certain enzymes in smaller compartments of the cell. This limits the availability of these enzymes to convert sugar to biobutanol in significant quantities and at high rates. Butamax developed modified genes that express key enzymes in the larger ‘cytosol’ area… Login to continue
