Figure 4From: Cocktail δ-integration: a novel method to construct cellulolytic enzyme expression ratio-optimized yeast strainsDetermination of cellulase gene copy number of cellulase-expressing yeast strains. Gray bar, β-glucosidase; white bar, endoglucanase; black bar, cellobiohydrolase. MT8-1/IBEC, conventional integrated strain; MT8-1/δBEC, conventional δ-integrated strain; MT8-1/cocδBEC1, cocktail δ-integrated strain; MT8-1/cocδBEC2 and MT8-1/cocδBEC3, repeated cocktail δ-integrated strain; MT8-1, wild-type strain. Data are averages from three independent experiments.Back to article page
