5-Hydroxymethylfurfural and levulinic acid are versatile biomass-derived platform compounds that can be used to synthesize a broad range of chemicals, and are currently derived from petroleum. This study focused on optimization of reaction conditions for formation of levulinic acid from marine algal biomass Gelidium amansii using acid catalyst and by using statistical approach. By this approach, optimal conditions for production of levulinic acid was found as follows: 160.0℃, 43.1 min and 3.0%. Under optimized conditions for levulinic acid formation, glucose and galactose concentrations were minimized. In addition, levulinic acid formed at a high reaction temperature, long reaction time, and high catalyst concentration. Based on the overall results, chemical intermediates (HMF and levulinic acid) produced from marine biomass will be used as platform compounds for use in synthesis of a broad range of chemicals currently obtained from petroleum. Our results may provide useful information in regard to development of more economical and efficient systems for production of sugars and chemicals from marine-biomass.
