This result was better than for a co-immobilization of M. purpureus only.From this investigation, the simultaneous fermentation of sweet potato starch to ethanol can be achieved through the
Co-immobilization of S. cerevisiae and A. oryzae, M. purpureus or
both. The mixed blends of molds and S. cerevisiae gave the highest
ethanol yields and the shortest fermentation times. It is a potential
process for ethanol production from sweet potato starch. Acknowledgment
