Optimization of Reducing Sugar production from Acid Pretreatment of Ipomoea repens

Abstract

Ipomoea repens   is a weed and abundant   bio-resources for reducing   sugar production. The cellulose of    Ipomoea repens can be converted into reducing sugar and biofuels. The   research reports the   evaluation of  Ipomoea repens to produce reducing sugars through acid hydrolysis. The effects of temperature (60–100 o C), acid concentration (1–6%), and time (30–60 min) were investigated using a statistical experimental design. Scanning Electron Microscopy was used in elemental and morphological analysis. The reducing sugar yield was influenced by the interaction of (acid concentration. acid concentration), which was found to be the most significant quadratic term. The optimal parameter conditions were found to be temperature (100 oC), reaction time (45 min), and acid concentration (3.50%), with a reducing sugar yield of 6.203%.The result of elemental   analysis showed  , Oxygen(%) 38.98 ±1.717 , carbon(%) 60.18 ±2.19 , Calcium (%) 2.0 ±0.00 , Silver (%)0.26 ±0.00 ,  Potassium (mg/kg) 14100 ±229 , Sodium (mg/kg) 228±291, Nitrogen (%) 2.10±0.02  and tellurium(%) 0.68±0.00  According to the   findings, biomass can be used as a potential feed stock for the production of reducing sugar,  biofuels and other biological derived   chemicals.
