These studies are considered novel as we combined efficient hydrolysis, fermentation, and ABE recovery technologies in a single process. Use of dilute sulfuric acid is advantageous in the hydrolysis of cellulosic biomass as it hydrolyzes much of the hemicellulose to pentose sugars.
The residual cellulose and hemicellulose was hydrolyzed by enzymes. Application of alkali solublizes hemicellulose but does not hydrolyze it
