In this study, we screened several fungi for the production of alpha-ethyl glucoside (alpha-EG) and successfully identified Aspergillus kawachii N-3 that exhibited high activity for both alpha-glucosidase and amylase. High-yield production of alpha-EG from maltose or soluble starch was achieved at pH6 and 30degC in the presence of 30% ethanol. Moreover, continuous alpha-EG production from a commercial syrup (Sun-Oligo: Sanmatsu Co., Ltd.) using A. kawachii N-3 immobilized on a non-woven polyester fabric was successfully accomplished for a period of >90 days.
