A FERMENTATION PROCESS

摘要

Methods and systems for the production of one or more lipid products from a gaseous substrate using a two stage fermentation process. The method providing a gaseous substrate comprising CO2 and H2 to a first bioreactor containing a culture or one or more microorganisms, and fermenting the substrate to produce acetate. The acetate from the first bioreactor is then provided to a second bioreactor, where it is used as a substrate for fermentation to lipids by one or more yeasts.
