Free cells were more sensitive to ethanol than immobilized cells. Ethanol production of free and immobilized cells were 4.93 and 4.91%. without e The ethanol production rate of
free and immobilized cells also decreased from 1.72 and
1.67 g L1 h1 without ethanol supplementation to 0.30 and
0.74 g L1 h1 with 10% ethanol supplementation, respectivelythanol supplementation and decreased to 0.68 and 1.80% at 10% ethanol
