In this research, different methods were tested to make corn stalk easier to break down into useful sugars. They tried three methods: using diluted acid, diluted alkali, and sodium sulfite anhydrous. After testing these methods, they found that treating corn stalk with sodium sulfite anhydrous was the best way to improve enzymatic breakdown. The best conditions for breaking down the corn stalk were at 50℃, pH 4.8, with a certain amount of the enzyme, and for 24 hours. With this method, the rate of breakdown was 39.07%, which is much higher compared to untreated corn stalk. So, using sodium sulfite anhydrous can make it easier to turn corn stalk into useful things.
