FERMENTATION PROCESS

摘要

The invention provides methods and systems for the production of lipid products from a gaseous substrate using a two stage fermentation process. The method comprises providing a gaseous substrate comprising CO or CO2 and H2 or mixtures thereof, 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 microalgae.

主权项

1. A method for producing at least one lipid product from a gaseous substrate, the method comprising:
a) receiving a gaseous substrate in a first bioreactor comprising a culture of at least one microorganism in a liquid nutrient medium, and fermenting the gaseous substrate to produce a product selected from an acid or an acid and an alcohol; and b) passing at least a portion of the acid product to a second bioreactor comprising a culture of at least one microalgae in a liquid nutrient medium, and fermenting the acid to produce at least one lipid product.
