2011/1/1/ · Abstract. High gravity (HG) fermentations save energy consumption for both ethanol distillation and subsequent discharge treatment. However, yeast cells suffer from various stresses under HG conditions, which often result in stuck or sluggish fermentations with more sugars remained unfermented, and thus reduce efficiency of ethanol fermentation.
