In this study, scientists looked at how treating cellulose with strong sulfuric acid can change it to make it easier to turn into glucose. They used very little acid to treat the cellulose, making it change from one form to another. The acid treatment made the cellulose easier to break down with enzymes, increasing the amount of glucose produced. By using this method, they could turn 57% of untreated cellulose into glucose, but with the acid-treated cellulose, they got 85% glucose yield. The researchers found that certain changes in the cellulose structure, like turning into cellulose II form, were crucial in getting more glucose from the cellulose. This study shows that using a little sulfuric acid can help break down cellulose more effectively for making glucose.
