The production of fermentable sugars from renewable sources is a challenge. An attempt was made to exploit glycogen as a potential feedstock for the production of glucose. The microwave-assisted acidic hydrolysis was applied for glycogen decomposition for the first time. The optimal conditions for the hydrolysis reaction (yield of glucose -62 wt.%) were identified: microwave irradiation time -10 min and concentration of acid -1 M HCl. Microwave irradiation has dramatically reduced the reaction time from more than 6 h (at 80 uC under an oil bath) to 10 min. 13 C NMR spectroscopy was employed to monitor the progress of the hydrolysis reaction. HPLC analysis was employed to evaluate the yield of glucose. Thus, the viability of the use of glycogen as an economically and environmentally benign precursor to the production of glucose has been demonstrated.
A graphene supported silicotungstic acid catalyst was synthesized sonochemically. Glucose yield was dramatically increased by reusable HSiW/G in biomass hydrolysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
