The researchers studied how treating corn stalk with bisulfite affects the breakdown of the plant material by enzymes. They found that using more bisulfite at higher temperatures increased the amount of sugar produced from the corn stalk. The best results were seen at 190℃ with a 30-minute treatment time and 7% bisulfite, leading to a high conversion rate of 81.04% and a glucose yield of 71.91%. They also discovered that maintaining a pH value between 4.2-4.7 significantly improved the efficiency of the process.
