Researchers found a way to make sugar from paddy straw waste by treating it with a little acid and then breaking it down with enzymes. They figured out that using 1% sulfuric acid followed by enzymatic hydrolysis produced lots of sugar. By optimizing the enzyme process at pH 5, 50°C, and using 0.10 mL of enzyme, they got the most sugar yield - 4.55 g/L. This method can help turn leftover paddy straw into fermentable sugar for other uses.
