Abstract: The disclosure provides methods and systems to produce 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. Tail gas from the second bioreactor is recycled to the first bioreactor.

Abstract: The invention is directed to a device and associated method for recovering at least one product from a fermentation broth. The invention relates to the use of a vacuum distillation vessel to recover products, such as ethanol, from a fermentation broth, where the fermentation broth comprises viable microbial biomass, and where the recovery of the product is completed in such a manner to ensure the viability of the microbial biomass. The invention provides for product recovery at an effective rate so as to prevent the accumulation of product in the fermentation broth. To ensure the viability of the microbial biomass, the invention is designed to reduce the amount of stress on the microbial biomass. By ensuring the viability of the microbial biomass, the microbial biomass may be recycled and reused in the fermentation process, which may result in an increased efficiency of the fermentation process.

Abstract: The disclosure relates to the system comprising a combination of a primary bioreactor with a secondary bioreactor to convert a gaseous stream comprising CO and optionally H2, or CO2 and H2 to at least one target product. Bioreactors may be any combination of aerobic and anaerobic, batch and continuous. The bioreactors comprise fermenting microorganisms that may typically be bacterial or fungal.

Abstract: The invention provides for methods by which the economics of the gas fermentation process are improved. The invention provides for the integration of a fermentation process, with an industrial process and an electrolyzer process. The invention provides for the intermittent supply of electrolyzer feedstock from the electrolyzer process to the bioreactor for fermentation. The electrolyzer feedstock may displace at least a portion of the C1 feedstock from the industrial process. The electrolyzer feedstock may supplement the C1 feedstock from the industrial process. Whether or not the electrolyzer feedstock supplements or displaces the C1 feedstock with electrolyzer feedstock may be based upon a function of the cost per unit of the C1 feedstock, the cost per unit of the electrolyzer feedstock, and the value per unit of the fermentation product.

Abstract: The disclosure relates to the combination of a primary fermentation that converts gas to acetate with a secondary fermentation that converts acetate to a target product. Preferably, the gas contains carbon dioxide, such that the disclosure enables the fixation of carbon dioxide into useful products. The fermentations may be any combination of aerobic and anaerobic, batch and continuous. The fermenting microorganisms may typically be bacterial or fungal.
