The application of a repeated fed-batch rapid ethanol fermentation employing immobilized yeast cells accompanied by an activated carbon extraction system has been investigated in an attempt to increase product yield. Immobilized and free yeast cells were used to effect ethanol fermentations in a simplified nitrogen-free medium containing only glucose and mineral salts. Repeatedly, fermentation broth with a high ethanol concentration (80 to 100 g/L) was extracted using activated carbon beads (BACM) and the resulting broth of low ethanol content (< 50 g/L) was recycled back for further fermentations. The maximum ethanol productivity achieved in this system was 25 g/L/h. 7 figures, 1 table.
