Biosugar production from marine algae Kappaphycus alvarezii by acid hydrolysis

Marine algae are a promising alternative feedstock for biosugar production since they rich in carbohydrate content, do not compete with food crops land, and fast growing. This study used the marine Kappaphycus alvarezii as to produce biosugar. In order convert algal biomass biosugar, hydrolysis is needed breakdown complex structure of lignocellulosic material tissues. this study, process was performed using different acid concentration (H2SO4 0.1-0.3 M); concentrations alga (0.5%, 1%, 1.5% 2%); reaction times (0-120 min). The results showed that highest yield obtained at an 0.5% 0.1 M, yielding sugar content 0.54 g sugar/g dry biomass. These indicate method economic from algae.
