Abstract excerpt
In order to produce 2,3-butanediol (2,3-BD) with a high titer, it is necessary to engineer Saccharomyces cerevisiae by deleting the competing pathway and overexpressing the 2,3-BD biosynthetic pathway. A pyruvate decarboxylase (Pdc)-deficient mutant was constructed and evolved for rapid glucose consumption without ethanol production. Genome re-sequencing of the evolved strain (SOS4) revealed a point mutation...
