Corn Straw Transformed into Abundant Renewable Fuel with Groundbreaking Pretreatment
To get more sugar from corn straw, scientists treated it with acid and alkali. This process boosted the cellulose content to 91.34% and removed much of the hemicellulose and lignin. The cellulose's crystalline structure increased by 124.13%. The acid and alkali caused damage to the hemicellulose and lignin molecules. Images revealed more cracks and holes on the fibers. Enzymatic testing confirmed that the treated corn straw yielded 65.17% of reducing sugar, a huge improvement over the 13.66% from untreated straw. This method cut down the time needed for enzymolysis by about 24 hours. This means using acid and alkali resulted in a much higher sugar conversion rate from corn straw.
