粒度为100、200和300μm的自絮凝酵母颗粒群体总麦角固醇、游离麦角固醇及海藻糖含量与粒度大小成正相关,但在粒度为400μm的絮凝颗粒群体中总麦角固醇、游离麦角固醇及海藻糖含量呈下降趋势,与其乙醇耐性低于300μm絮凝颗粒的结果相一致。
Potentially, distillage could be fully recycled during continuous ethanol fermentation using self-flocculating yeast cells as yeast cells were self-immobilized and less inhibitory by-products were expected in the waste distillage.
