This study focused on immobilization of Saccharomyces coreanus to support materials and ethanol fermentation by the immobilized yeast. Three porous media as support material were surveyed; synthetic zeolite, aluminum silicate and granular activated carbon. Amount of yeast (determined by organic matter content) immobilized into/on support materials was lowest in fermentation using aluminum silicate as supports. Glucose as substrate of ethanol fermentation was easily sorbed more than ethanol into/on 3 types of support materials. Of these, absorbed amount of glucose and ethanol into/ on activated carbon was highest. The ethanol was actively produced for 16 hours in fermentation processes by yeast immobilized into/on aluminum silicate and activated carbon, produced after 16 hours by yeast immobilized into/on zeolite. The produced ethanol concentration after 24 h was as follows; 24.2 g/L by using aluminum silicate, 19.3 g/L by activated carbon and 16.1 g/L by zeolite.
