Mexican researchers produce ethanol from sugarcane waste
Researchers at the Universidad Autónoma de Querétaro in Mexico have produced cellulosic ethanol from sugarcane and other crop waste. Using a hydrolysis pre-treatment, then fermenting the cane with Saccharomyces cerevisiae yeast, the researchers used a molecular sieve and dehydrated the ethanol into anhydrous ethanol. The resulting liquid can be blended up to 20% in standard internal combustion engines, and is competitive with gasoline production, according to the scientists. 

In Mexico, researchers at the Universidad Autónoma de Querétaro have produced cellulosic ethanol from sugarcane trash and other crop waste using a hydrolysis pre-treatment and then Saccharomyces cerevisiae yeast for fermentation before passing through standard processes to remove most of the water through production of steam. Using a molecular sieve, the hydrous ethanol is dehydrated into anhydrous ethanol. The researchers say their process is competitive with gasoline production. They argue it can be blended up to 20% in standard gasoline engines.
