Abstract: The enzymatic hydrolysis of algae has already been investigated for bioethanol production. However, the effect of varying the sequence of adding enzymes on the extraction of sugars from microalgal biomass has not been explored yet. In addition, there is no attempt describing the effect of algal cellulose on starch hydrolysis of algae using α-amylase. This contribution presents the results of the enzymatic hydrolysis kinetics of mixed microalgal biomass under different sequence of adding enzymes and operational conditions. In the proposed kinetic model, the factors including enzymes inactivation, product inhibition, and the inhibitory effect of cellulose on α-amylase were considered. The kinetic model performed well in predicting algal carbohydrates hydrolysis trends at experimental conditions.
