| Summary: | High quantity of starch in Indonesia allows many opportunities for its applications. One potential application of starch is its economics conversion to bioethanol. Starch can be converted to bioethanol through several enzymatic processes. The first step is conversion of starch into oligosaccharides. In this step, the amount of the obtained oligosaccharide could be optimalized by using bioreactor membrane. In this research, bioreactor membrane was made using poly(methyl methacrylate) membrane and crude extract of α-amylase enzyme, immobilized into the polymer matrix. The poly(methyl methacrylate) membrane was synthesized with solvent evaporation for 10 minutes and was annealed at 65 °C for 2 minutes. The crude extract of α-amylase enzyme was succesfully trapped on polymer matrix with a moderate activity. The improvements of the activity of fabricated bioreactor membrane will be the objective of a continuation of this research to obtain higher performance of such a bioreactor membrane. |
