Anaerobic acidification of sugar-containing wastewater for biotechnological production of organic acids and ethanol

摘要: Anaerobic acidification of sugars can produce some useful end-products such as alcohol, volatile fatty acids (e.g. acetate, propionate, and butyrate) lactic acid. The production is highly dependent on factors including pH, temperature, hydraulic retention time the types sugar being fermented. Results this current study indicate that pH played significant roles in determining end products from anaerobic maltose glucose. Under uncontrolled ceased when reactor dropped below 5 while glucose continued produced ethanol main end-product. controlled acid was found to be dominant end-product both at 5. Acetate fermented neutral (6 7). Short (HRT) 2 days could induce However, stop short HRT applied reactor. This finding for industrial fermentation waste management systems, selective different organic achieved by managing
