Continuous glycerol production was examined in a bioreactor packed with immobilized yeast cells (Saccharomyces uvarum) with agarose. The optimum pH value was 8.0 for adding sodium solfite in feed solution. When the ethanol concentration was 20-30 kg/m^3,the maximum yield of glycerol from glucose was obtained.Using a feed solution containing 180kg/m^3 of glucose and adding 100kg/m^3 of sodium fultite, 50 to 60 kg/m^3 of glycerol and 23 to 28 kg/m^3 of ethanol were obtained at the residence time of 40 h and a temperature of 303K. The simulated values from immobilized yeast-cells properties, which were activity, and yields of ethanol and glycerol from glucose in batch or continuous operation, almost agreed with the observed data in continuous operation.
