Fig. 1From: Enhanced production of 2,3-butanediol by engineered Saccharomyces cerevisiae through fine-tuning of pyruvate decarboxylase and NADH oxidase activitiesComparison of a Glycerol, 2,3-BD, and ethanol yields, and b 2,3-BD productivity in batch fermentation for the control and four engineered strains expressing CtPDC1 gene with different expression levels. Values are calculated from experiments in Additional file 1: Figure S5. Results are the averages of duplicate experiments and error bars indicate standard deviationBack to article page
