Processes, as well as associated systems and computer program (software) products, are disclosed for the biological conversion of CO into desired end products such as ethanol. The control methodologies used for these processes can advantageously result in a reduced time required for a batch operation or other initial operating period, prior to achieving a continuous operation, which may be demarcated either by the addition of fresh culture medium at a defined flow rate or by another process initiation target. The control methodologies may alternatively, or in combination, improve a process performance parameter, such as productivity of the desired end product or bacterial growth rate, during this batch operation or other initial operating period.

Control of bioreactor processes

The invention relates to a method for producing products by microbial fermentation. The method comprises first converting a feed stream containing methane to a gaseous substrate comprising CO, of the invention include converting CO H, and COusing a steam reforming zone and a water gas shift zone. The gaseous substrate is then converted to products such as alcohols and/or acids by to one or more products including alcohols and/or acids by fermentation using a carboxydotrophic microorganism.

Carbon capture in fermentation

A bioreactor system is provided for continuous fermentation of a gaseous substrate, said system comprising two or more primary bioreactors and one or more secondary bioreactors connected by a central bleed line. Further provided is a process for inoculating multiple bioreactors utilizing a central bleed line, said process comprising passing fermentation broth from a first primary bioreactor to other primary bioreactors and/or secondary bioreactors via a central bleed line. Further provided is a process for maintaining stable fermentation of a gaseous substrate across multiple bioreactors, said process comprising providing fermentation broth from one or more operational primary bioreactors to one or more secondary bioreactors via a central bleed line.

Multiple reactor system for continuous gas fermentation

Methods of capturing carbon by microbial fermentation of a gaseous substrate comprising CO. The methods include converting CO to one or more products including alcohols and/or acids and optionally capturing CO2 to improve overall carbon capture. In certain aspects, also disclosed are to processes for producing alcohols, particularly ethanol, from industrial waste streams, particularly steel mill off-gas.

Carbon capture in fermentation using blended gaseous substrate

The invention relates to a process for optimizing the production of ethanol by microbial fermentation, particularly microbial fermentation of substrates comprising CO. The process involves monitoring the hydrogen production by the microorganism, determining an optimum hydrogen production and adjusting the substrate supply rate in response to a change in the hydrogen production thereby keeping the hydrogen production within a desired range.

Alcohol production process

Methods for improving the efficiency of 2,3-butanediol fermentations are disclosed. More specifically methods of increasing the butanediol productivity from the anaerobic fermentation of a substrate comprising carbon monoxide or carbon monoxide and hydrogen by one or more caboxydotrophic acetogenic bacteria are disclosed. The method includes supplying a hydrogen depleted substrate to increase butanediol productivity. The method includes producing butanediol at a volumetric productivity rate of at least 15 g/L/day.

Fermentation process for controlling butanediol production

The present invention relates to methods for sustaining a microbial culture during periods of limited substrate supply. In accordance with the methods of the invention, a microbial culture comprising carboxydotrophic bacteria can be sustained during periods of limited substrate supply by maintaining the temperature of the microbial culture at a temperature below an optimum operating temperature. Examples of periods of limited substrate supply include when the microbial culture is transported to a remote location or during time when it is stored.

Methods of sustaining culture viability

The invention relates to methods of capturing carbon by microbial fermentation of a gaseous substrate comprising CO. The methods of the invention include converting CO to one or more products including alcohols and/or acids and optionally capturing CO2 to improve overall carbon capture. In certain aspects, the invention relates to processes for producing alcohols, particularly ethanol, from industrial waste streams, particularly steel mill off-gas.

The invention relates to biological processes for producing one or more desired products, including alcohols such as ethanol and butanol. The processes comprise carrying out first and second fermentations of substrates in first and second bioreactors, wherein each fermentation produces one or more desired products and/or one or more by-products that can be utilized in the other fermentation. A product and/or by-product of the first fermentation is introduced to the second bioreactor during the fermentation, and a product and/or by-product of the second fermentation is introduced to the first bioreactor during the fermentation.

The invention relates to methods for the production of alcohols by microbial fermentation, particularly microbial fermentation of substrates comprising glycerol and/or acetate, to butanol.

The invention relates to the production of alcohols by microbial fermentation, particularly to production of alcohols by microbial fermentation of substrates comprising CO. It more particularly relates to processes for the production of alcohols from their corresponding acids in the presence of a substrate comprising CO. In particular embodiments, a fermentation reaction producing acid(s) and optionally alcohol(s) is perturbed such that at least a portion one or more of acid(s) is converted to alcohol.
