Abstract: Life time of immobilized Pichia stipitis yeast cells was prolonged significantly when the gel was formed with aluminium alginate instead of calcium alginate.Endurance against phosphate of aluminium alginate gel was increased 3 times than that of calcium alginate gel.Glucose-xylose mixture could be co-fermented to ethanol by immobilized Pichia stipitis yeast cells of aluminium alginate.The concentration of ethanol in final broth was enhanced from 26.0 g/L to 27.3 g/L,and utilization ratio of total sugar was 93.7%.

Key words: Pichia stipitis, aluminium alginate, ethanol
