摘要:
The production of ethanol from carob pod extract by immobilizedS. cerevisiaecells on the mineral kissiris was investigated. The optimum conditions for carob pod extract fermentations were pH 3.5 ‐ 6.5, temperature 30°C and initial sugar concentration of 250g/l. A maximum ethanol concentration (64.5g/l), ethanol yield (28.3%) and sugar utilization (94%) was achieved at an initial sugar concentration of 250, 200 and 250g/l, respectively. In repeated batch fermentations, the immobilizedS. cerevisiaecells on kissiris retained their ability to produce ethanol for 30 days.
