Figure 2From: Increased isobutanol production in Saccharomyces cerevisiae by eliminating competing pathways and resolving cofactor imbalanceDisruption of genes related to pyruvate metabolism. (a) Genes investigated in this study. (b) Isobutanol production by single gene-deleted strains. All strains including the control strain (BSW100) were constructed by introducing pGK423-kivd, pGK425-ILV2, and pGK426-ADH6 plasmids. Isobutanol titers were determined at 72Â h after the fermentation start. Each data point represents the mean (SD) values obtained from 3 replicate fermentations.Back to article page
