To make corn stalks easier to turn into sugar, researchers used steam and alkali to treat them, along with enzymes. They found that this method reduced cellulose and hemicellulose levels in the corn stalks and increased the amount of sugar obtained. By pretreating the corn stalks with steam and alkaline solutions and then using enzymes at specific conditions, they achieved a higher yield of sugar from the corn stalks. The results showed a significant improvement in sugar production compared to untreated corn stalks. This approach helped break down the tough structure of the corn stalks, making it easier to extract sugar from them.
