Just as plants use solar energy to produce sugar, for example, from carbon dioxide (CO 2 ) and water in several steps, artificial photosynthesis uses renewable energies to produce valuable chemicals from CO 2 and water through electrolysis with the help of bacteria.
One way to mitigate high feedstock cost is to maximize conversion into the bioproduct of interest. This maximization, though, is limited because of the production of CO 2 during the conversion of sugar into acetyl-CoA in traditional fermentation processes. Acetogens are anaerobic bacteria, which cannot grow in oxygenated environments.
