Abstract
This experiment was attempted to improve ethanol productivity by immobilization of Kluyveromyces marxianus FO43 using Jerusalem artichoke powder. Sucrose medium was used to determine optimum conditions for cell immobilization. The optimum conditions were alginate concentration of 2%, bead size of 2 mm, a particle input ratio of 30 : 100, cultivation period of 24 hours, and substrate concentration of 10%(w/v). The immobilized cells produced the high concentrations of ethanol at pH
