Technology for a continuous ethanol fermentation process was developed by means of immobilized living cells using yeast cells and specially designed artificial resins.Yeast which has the ability to produce ethanol was screened from Saccharomyces genus and mixed with prepolymers of photocrosslinkable resin, then illuminated with an active ray (for example, chemical lamp) to change the prepolymers into three dimensional cross-linked polymers in which yeast was entrapped. Immobilized yeast processed into appropriate thinner sheet was packed in a fermentor and a diluted molasses solution fed to the fermentor. The fermentation temperature was kept at about 30-32°C and the pH at 4-5.As a result of a bench scale test (10 litres of ethanol a day) and pilot plant test (250 litres of ethanol a day), the constant activity of the yeast and high ethanol yield on sugar during long-term operation was confirmed and it was also established that the ethanol productivity was several times that of conventional suspended state batch system fermentation.
