Acid Hydrolysis from Corn Stover for Reducing Sugar

The aim of this study is to extract the reducing sugar by acid hydrolysis of corn stover. The corn stover was hydrolyzed by using H 2 SO 4 at different concentrations (0-6%, v/v),reaction times (15-180 min) at temperature 122 C with ratio of 1 g of corn stover to 20 ml of H 2 SO 4 solution. The samples were analyzed the reducing sugar by HPLC. The optimal conditions of acid hydrolysis was at 1% H 2 SO 4 (v/v), 122 C for 60 min, which produced 24.96 g/L of reducing sugar. The hydrolysed sample composed of 12.4 g/L of xylose, 2.9 g/l of glucose and 3.2 g/L of arabinose. Also, the Scanning Electron Microscopy (SEM) was analyzed the morphology of untreated and treated corn stover which showed the breakdown fibril of treated sample.
