Acid requires the application of distilled and dissolved acids in order to crack the lignocellulosic material’s rigid shape. Dilute sulfuric acid employed for acid pre-treatment of biomass such as maize, softwood [72]. This will be used to eliminate hemicellulose after alkali pre-treatment (lignin exclusion) results in comparatively pure cellulose, is the most commonly used acid. The benefit of acid pre-treatment is that there is often no need for a corresponding enzymatic hydrolysis step. This may be due to the fact that acid itself hydrolyses the biomass to generate fermentable sugars. Hemicellulose and lignin are solubilized with restricted degradation [74, 75].
