Yeast screening for effective production of alcohol from Jerusalem artichoke tubers as an alternative energy source was performed. Inulin assimilative strains with high alcohol tolera- nce were isolated from wild sources and cultured in the liquid media of Jerusalem artichoke powder varying its concentraion from 15 to 30%. As a result, four strains of 2,445 isolates showing the inulin assimilation were selected as alcohol fermentative and alcohol tolerant yeasts. These strains were assignated to be Kluyveromyces marxianus F043 and Kluyveromyces sp. F173, E040, and F334, respectively, by their cultural and physiological characteristics. The F043 strain produced ethanol of 98.1 g/l in the 25% Jerusalem artichoke medium for 3 days.
