Abstract: 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, CO2 or 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.

Abstract: Apparatuses and associated methods are described for the efficient evaluation of Cl-containing substrates, and especially for such evaluation conducted locally, or on-site, at a prospective facility for implementation of a biological conversion process for desired end product using a Cl carbon source. The exact composition of a given, industrial Cl-containing substrate, as well as the range in composition fluctuations, are generally difficult to reproduce at a remote facility (e.g., a laboratory or a pilot-scale or demonstration-scale process), as required for the accurate prediction/modeling of com?mercial performance to justify large capital expenditures for commercial scale-up.
