Abstract

|
|
To produce ethanol from Jerusalem artichoke powder efficiently, Kluyveromyces marxianus F043 cells were encapsulated in 2% sodium alginate and were cultured in batch reactor to investigate the fermentation properties, Batch culture of immobilized cells left for 4 days in 15% Jerusalem artichoke medium showed ethanol concentration of 3.38%(w/v) and ethanol yield to theoretical value of 54.20%, lower than 3.76%(w/v) and 71.13% for the culture of free cells. Addition of cellulase to 15∼20% Jerusalem artichoke media increased the production of ethanol, owing to remarkable reduction in consistency of the Suspension. So it was possible to achieve an ethanol concentration of 5.57%(w/v) arid an ethanol yield to theoretical value of 68.86% in even 20% Jerusalem artichoke medium by cultivation of immobilized cells for 4 days. The alginate beads shoved constant ethanol productivity after recycling 11 times (22 days) in repeated batch fermentation.
