Abstract: The invention provides a process for reducing bio-catalytic oxidation of a product in a post-production stream. More particularly the invention provides a process for reducing bio-catalytic oxidation of an alcohol in a product stream, the product stream comprising an alcohol product, dissolved carbon dioxide, and at least one enzyme capable of oxidizing the alcohol. The invention finds applicability in fermentation processes, wherein a C1-fixing microorganism utilizes a C1-containing substrate to produce a fermentation product.

Abstract: The disclosure provides for the integration of a CO-consuming process, such as a gas fermentation process, with a CO2 to CO conversion system. The disclosure is capable of utilizing a CO2-comprising gaseous substrate generated by an industrial process and provides for one or more removal modules to remove at least one constituent from a CO2-comprising gaseous substrate prior to passage of the gaseous substrate to a CO2 to CO conversion system. The disclosure may further comprise one or more pressure modules, one or more CO2 concentration modules, one or more O2 separation modules, and/or a water electrolysis module. Carbon conversion efficiency is increased by recycling CO2 produced by a CO-consuming process to the CO2 to CO conversion process.

Abstract: The invention is directed to a 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: This disclosure relates to analyzing a fermentation process that occurs in a bioreactor. Such a fermentation process may involve microbes consuming a substrate, and producing various metabolites. A computing device may train and execute one or more machine learning models to analyze such a fermentation process. Such a machine learning model may be configured to determine a current fermentation state of such a fermentation process as one example. As another example, a machine learning model may be configured to predict metabolite production of a fermentation process based on historical fermentation data and a window of control decisions for the fermentation process.

Abstract: The disclosure is directed to a process and apparatus for continuous gas fermentation with reduced accumulation of co-products. The disclosure relates to the use of both a vacuum distillation unit and a membrane separator to provide efficient product recovery, cell retention, and water recycling to maximize production of the fermentation products. The disclosure provides for continuous product recovery at an effective rate and minimizes the accumulation of co-products in the fermentation broth while ensuring the retention and viability of the C1-fixing microorganisms.

Abstract: An integrated process and system for the production of at least one gas fermentation product from a gaseous stream has been developed. The disclosure provides improved carbon utilization through both the recycle of a bioreactor tail gas via various different flow schemes and the employment of a CO2 to CO conversion system such as a reverse water gas shift unit. Recycling of the bioreactor tail gas and employment of a CO2 to CO conversion process provides for favourable H2:CO molar ratios of the feed to the gas fermentation bioreactor(s) for enhanced production of fermentation products. Bypass embodiments provide for optimal sizing of the reverse water gas shift unit to minimize cost.

Abstract: The disclosure provides methods to improve the economics of the gas fermentation process. A fermentation process is integrated with an industrial or syngas process and an reverse water gas shift process. An intermittent supply of reverse water gas shift process feedstock from the reverse water gas shift process is provided to the bioreactor for fermentation. The reverse water gas shift process feedstock may supplement or partially displace the C1 feedstock from the industrial or syngas process. Whether the reverse water gas shift process feedstock supplements or displaces the C1 feedstock may be based upon a function of the cost per unit of the C1 feedstock, the cost per unit of the reverse water gas shift process feedstock, and the value per unit of the fermentation product, or may depend upon the target gas ratio of the feedstock to the gas fermentation process.

Abstract: The disclosure provides for the integration of a fermentation process with at least one electrolysis process, a CO2 to CO conversion unit, and a C1-generating industrial process. In particular, the disclosure provides process and a system for utilizing electrolysis products, for example H2 and/or O2 in a CO2 to CO conversion unit to improve the process efficiency of at least one of the fermentation processes or the C1-generating industrial process. More particularly, the disclosure provides a process in which H2 generated by electrolysis is passed to a CO2 to CO conversion unit to improve the substrate efficiency for a fermentation process, and the O2 generated by electrolysis process is used to improve the composition of the C1-containing tail gas generated by the C1-generating industrial process.
