Retrieved from https://hdl.handle.net/1911/80084.https://hdl.handle.net/1911/80084The invention relates to the development of appropriate cultivation conditions for a bacteria to grow anaerobically (fermentatively) on a glycerol substrate. The method requires culturing bacteria having a functional 1,2-propanediol pathway and a functional type II glycerol dehydrogenase-dihydroxyacetone kinase pathway in a culture medium containing high concentrations of glycerol, a neutral to mildly acidic pH, low levels of potassium and phosphate, and high levels of CO2, such that glycerol is thus converted into a desirable product, such as ethanol, hydrogen, formate, succinate, or 1,2-propanediol.12 ppengUtility patentUS8129157B2
