Abstract:
Escherichia coli is the organism of choice for the expression of a wide variety of recombinant proteins for therapeutic, diagnostic and industrial applications. E. coli generates acetic acid (acetate) as an undesirable by-product that has several negative effects on protein production. Various strategies have been developed to limit acetate accumulation or reduce its negative effects to increase the productivity of recombinant proteins. This article reviews recent strategies for reducing or eliminating acetate, including approaches that optimize the protein production process as well as those that involve modifying the host organism itself.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
