Abstract
A byproduct of Tofu or Okara was experimentally treated by simultaneous saccharification and fermentation process (SSF) to find some operational conditions for its utilization. Baker yeast could produce ethanol from glucose under the conditions for enzymatic saccharification by cellulase. Lower production yield of ethanol from reducing sugars showed that the saccharification of Okara produced some reducing sugars which could not be utilized by baker yeast. In SSF of Okara, higher initial concentration of reducing sugar resulted in higher production of ethanol.
