Researchers studied how to break down wheat straw into glucose more efficiently by treating it with acid before using enzymes. They found that by pretreating the straw with sulfuric acid under specific conditions, they were able to increase the glucose yield by 50% compared to untreated straw. The optimal conditions for acid pretreatment were 80°C temperature, 4% acid concentration, and a 1:25 ratio of straw to water. For enzymatic hydrolysis, the best conditions were 50°C temperature, pH 5.2, and 25 FPU of dry enzyme with 0.1 mg of dry MgSO4/g. The process took 6 hours for acid pretreatment and 12 hours for enzymatic hydrolysis, resulting in a glucose yield of 34.5%.
