In this study, scientists aimed to turn corn straw into sugar for making bioenergy using two steps. First, they treated the straw with chemicals and high pressure to break it down and remove lignin. This process increased the breakdown of lignin, hemicellulose, and cellulose in the straw compared to untreated straw. Next, they used enzymes to break down the pretreated straw, resulting in the conversion of the straw into small sugar molecules. The researchers found that the combined approach effectively converted the straw into sugar, yielding high amounts of reducing sugar and breaking down cellulose and hemicellulose in the straw significantly. The process showed promising results in breaking down corn straw for potential bioenergy production.
