Fig. 2From: Production of 2,3-butanediol from glucose and cassava hydrolysates by metabolically engineered industrial polyploid Saccharomyces cerevisiaeIn vitro activity assay of endogenous PDC in engineered S. cerevisiae strains. Assays were replicated by four independent experiments. 1: 4-JHS200 (the control host strain); 2: 4-PDC1d (only PDC1 disrupted); 3: 4-PDC5d (only PDC5 disrupted); 4: 4-PDC6d (only PDC6 disrupted); 5: 4-PDC16d (PDC1 and PDC6 disrupted); 6: 4-PDC56d (PDC5 and PDC6 disrupted)Back to article page
