由于污染问题，酒糟生产是乙醇工业生产中最重要和最具挑战性的问题之一。本研究采用甘蔗糖蜜发酵乙醇得到的酒糟代替水制备发酵培养基。酿酒酵母F-727是从10个测试的酵母菌株中选出的。研究了氮、磷和镁的营养需求以及接种量的影响。当使用酒糟代替淡水时，所需的营养物质会减少；在淡水中实现了 50% 的产率，同时提高了发酵效率。关键词：酒糟、乙醇发酵、酿酒酵母 非洲生物技术杂志，第 13 卷(47) 4390-4398
Vinasse production is one of the most significant and challenging issues in the industrial production of ethanol due to pollution problems. In this study, vinasse obtained from ethanol by fermentation of sugarcane molasses was used instead of water to prepare the fermentation medium. Saccharomyces cerevisiae F-727 was selected from 10 tested yeast strains. Nutritional requirements of nitrogen, phosphorous and magnesium, as well as the effect of inoculum size were studied. There was a decrease in required nutrients when vinasse was used instead of fresh water; and 50% yield was achieved in fresh water together with an improved efficiency of the fermentation.
