Therefore, the co-immobilized gel bead containing 0.2 g A. oryzae mycelium and 5 106 cells mL1 S. cereviaise
proved to be the best for ethanol production. In co-immobilization studies using 0.1 g M. purpureus mycelium
and 5 105 e107 cells mL1 yeast, residual sugars accumulated at the initial stage of fermentation but decreased after 3 days. The residual sugar was utilized quickly in the fermentation process
