Abstract

The potential of producing reducing sugars from waste biomass (that which is left after lipid extraction) of Chlorella vulgaris by acid hydrolysis was investigated. Three factors, namely, temperature, acid concentration and reaction time were considered in the optimization of acid hydrolysis. Of the three, temperature was found to have no significant effect on reducing sugar yield and was not considered in optimization. Following Central Composite Design, Response Surface Methodology (RSM) predicated that the optimum acid concentration and reaction time were 3.71% and 73.98 min, respectively, with the maximum reducing sugar yield of 44.96%. Confirmatory test was done to validate the optimum condition obtained from RSM in which a 2.5% error between the predicted and experimental value was obtained.
