Dilute sulfuric acid was used to treat wheat straw at lower temperatures in this study. The researchers looked at how the amount of straw and liquid, acid concentration, time, and temperature affected the breakdown of the straw. They found that the best conditions were using a ratio of 1 part straw to 8 parts liquid, with 0.6% acid, for 1 hour at 160°C. Under these conditions, they were able to produce 50.34 grams of reducing sugars per liter, which was 61.96% of the maximum possible amount.
