초록
Various fungi were isolated from Korean traditional Nuruk and identified as ten types of fungal strains such as L. corymbifera, L. ramose, S. racemosum, R. oryzae, R. pusillus, M. racemosus, M. circinelloide, A. luchuensis, A. flavus, and A. fumigatus. Among them, four strains (A.fumigatus, A. luchuensis, A. flavus, and R. oryzae) exhibited relatively high glucoamylase activities. When the optimum reaction temperatures were verified for glucoamylase activity, A. fumigatus, A. luchuensis, and A. flavus showed the highest glucoamylase activity at 60°C, and R. oryzae showed the highest glucoamylase activity at 50°C. When simultaneous saccharification and fermentations were performed with yeast, R. oryzae showed the fastest starch degradation rate (1.17 ± 0.10 g/L·h) and the highest ethanol production (17.17 ± 1.46 g/L) for 72 hours.
