Industrial fermentation using bacteria, yeast and other microbes to produce specific products has the potential to reduce future dependence on fossil-fuel-derived chemicals. To further the economic viability of industrial fermentation processes, engineers have turned to genetic modification to stimulate production of a specific metabolic product, increase tolerance of the microbe to particular process conditions and increase product yields.
