Flocculating yeast
strain is superior for developing efficient ethanol fermentation
process [9]. The productivity in this study was 8.8 g L1 h1, while it
was 2.3 g L1 h1 in the continuous ethanol fermentation of thick
juice using immobilized yeast cells, and it could not perform at
dilution rate of 0.05 h1 due to intensive yeast leaching from the
support
