Elektrofermentation von Acetoin


Electrode-assisted fermentation is a new strategy in anaerobic biotechnology.
It can be used for reactions in which the average oxidation state
of the end product is higher than the substrate. Here we show two applications
of an electrode-assisted fermentation for the anoxic production of
acetoin. The presented approaches in Shewanella oneidensis and
Escherichia coli utilize engineered metabolisms to achieve high product
yields of roughly 80 percent under strictly anoxic conditions.
