| Abstract: | Continuous fermentation of corn material using self flocculating yeast cells as an immobilization method at different ethanol distilled effluent recycling ratios was experimentally studied. The feasibility of the complete recycling of ethanol distilled effluent was discussed for further large scale utilization. Thus a simple and feasible method of solving distilled effluent pollution was presented for ethanol fermentation industry. |
