Acid Hydrolysis from Corn Stover for Reducing Sugar

Article Preview

Abstract:

The aim of this study is to extract the reducing sugar by acid hydrolysis of corn stover. The corn stover was hydrolyzed by using H2SO4 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 H2SO4 solution. The samples were analyzed the reducing sugar by HPLC. The optimal conditions of acid hydrolysis was at 1% H2SO4 (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.
