Hydrolysis for Optimal Sugar Release from Macroalgal Feedstock for Bioethanol Production
Bioethanol from macroalgal feedstock entails pretreatment and hydrolysis for synthesis of sugar followed by the fermentation. Macroalgal biomass is pretreated for size reduction, alter or removal of structural and compositional impediments prior to the enzyme hydrolysis. Most commonly used pretreatment method is mineral acid hydrolysis with H2SO4 and HCl at milder concentrations to releases simple sugars (such as xylose, arabinose, galactose, glucose). Acid hydrolysis of U.lactuca and E. intestinalis yielded 214.67mg/g and 239.94 mg/g of reducing sugar respectively. Enzyme was extracted from marine bacteria Vibrio parahaemolyticus and purified by the two-step purification that produced 61.82% yield with 2.97 fold purification. Enzyme hydrolysis of pretreated algal biomass produced one fold higher reducing sugar than acid hydrolysis
