Propionate Production from Carbon Monoxide by Synthetic Cocultures of Acetobacterium wieringae and Propionigenic Bacteria.

ABSTRACT: Gas fermentation is a promising way to convert CO-rich gases to chemicals. We studied the use of synthetic cocultures composed of carboxydotrophic and propionigenic bacteria to convert CO to propionate. So far, isolated carboxydotrophs cannot directly ferment CO to propionate, and therefore, this cocultivation approach was investigated. Four distinct synthetic cocultures were constructed, consisting of Acetobacterium wieringae (DSM 1911^T) and Pelobacter propionicus (DSM 2379^T), Ac. wieringae (DSM 1911^T) and Anaerotignum neopropionicum (DSM 3847^T), Ac. wieringae strain JM and P. propionicus (DSM 2379^T), and Ac. wieringae strain JM and An. neopropionicum (DSM 3847^T). Propionate was produced b
