A new method was developed to turn corn cobs into useful products in an environmentally friendly way. The researchers used a three-step process to break down the different parts of the corn cob: first, they converted hemicellulose into sugars, then removed lignin with a special treatment, and finally broke down cellulose. By doing this, they were able to extract sugars efficiently from hemicellulose and remove a significant amount of lignin. This process increased the conversion rate of cellulose, a type of plant fiber, improving with each cycle. They also used special tools to confirm physical and chemical changes in the corn cob. This approach of breaking down the different parts of the corn cob has potential for use in agriculture.
