Twenty-seven strains of starch utilizing yeasts were isolated from 30 samples of $quot;Nuruk$quot;, a traditional starter in Korea. These strains were identified as ten species belonging to four genera; Hansenula anomaly (six strains), Harasenula sydowiorum (two strains), Saccharomycopsis fibuligera (four strains), Schwanniomyces occidentalis (two strains), Candida fabianii(two strains), Candida famata(one strain), Candida hydrocarbofumarica (three strains), Candida silvicola (one strain), Candida steatolytica (four strains) and Candida tropicalis (two strains). Saccharomycopsis fibuligera Nu-01, Nu-08, Nu-12 and Nu-27 produced much amylase, and one of these, Saccharomycopsis fibuligera Nu-12 showed the highest amylase activity (16.9 IU/㎖). Among the isolates, the strains of Hansenula anomaly were exhibited relatively high specific growth rate in the medium used starch as a carbon source, and ethanol fermentation by the strains of Candida hydrocarbofumarica was not observed.
