摘　　要：在重金属污染矿区种植能源甘蔗,初步筛选出了生物量大、可发酵糖含量高,适于乙醇发酵的能源甘蔗品种——粤糖94-128。甘蔗汁的发酵试验表明:采用酿酒酵母Saccharomyces cerevisiae(S.cerevisiae)2.8菌株发酵时,发酵液残糖含量较低,乙醇的体积分数可达到12%以上,因此该菌株可作为发酵含重金属甘蔗汁的酵母菌株。Nine sugarcane varieties were planted in heavy metal polluted soils as the materials for fuel ethanol, Yuetang 94-128 was screened for its high biomass and fermentable sugar contents. Fermentation tests showed that Saccharomyces cerevisiae （S. cerevisiae） 2.8 was suitable for sugarcane juice fermentation, and the remnant sugar content was lower and the ethanol content can reached to 12%.
