A process for producing and controlling pyruvate derived products during the fermentation of a CO containing substrate by an acetogenic carboxydotrophic microorganism has been developed. The process involves increasing the concentration of at least one nutrient selected from the group consisting of vitamin B1, vitamin B5, vitamin B7 and mixtures thereof above the cellular requirement of the microorganism. When the concentration is increased, the production of 2,3-butanediol (2,3-BDO) increases whereas the production of the other metabolites is virtually unchanged. The effect is reversible so that when the concentration is decreased, the production of 2,3-BDO is also decreased. This allows one to control the ratio of ethanol: 2,3-BDO to a desired value which can vary from 4:1 to 1:2.

The invention provides schemes for the integration of a fermentation process, with an electrolysis process, and a C1-generating industrial process. In particular, the invention provides process for utilizing electrolysis products, for example H_(2 )and/or O_(2), to improve the process efficiency of at least one of the fermentation process or the C1-generating industrial process. More particularly, the invention provides a process whereby, H_(2 )generated by electrolysis is used to improve the substrate efficiency for a fermentation process, and the O_(2 )generated by the electrolysis process is used to improve the composition of the C1-containing tail gas generated by the C1-generating industrial process.


Improvements in biological conversion processes and associated apparatuses are disclosed for the generation of useful end products such as ethanol, through metabolic pathways of C1-fixing bacteria that utilize, as a nutrient, a C1-carbon source from a C1-containing substrate such as an industrial waste gas. Particular aspects of the disclosure relate to the downstream recovery of ethanol and/or isopropanol from bleed and permeate streams and more particularly to performing such recovery with improved efficiency that can advantageously reduce capital (e.g., equipment) and/or operating (e.g., utility) costs. Particular aspects related to the downstream recovery of ethanol and/or isopropanol using a low pressure separator having an internal divider.

The invention provides genetically engineered microorganisms with altered carbon monoxide dehydrogenase (CODH) activity and methods related thereto. In particular, the invention provides a genetically engineered carboxydotrophic acetogenic bacterium having decreased or eliminated activity of CODH1 and/or CODH2. In certain embodiments, the bacterium may also have increased activity of CODH/ACS. The invention further provides a method for producing a product by culturing the bacterium in the presence of a gaseous substrate comprising one or more of carbon monoxide, carbon dioxide, and hydrogen.

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 operat 5 ion 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 10 this batch operation or other initial operating period.


The invention relates to a genetically engineered bacterium comprising an energy-generating fermentation pathway and methods related thereto. In particular, the invention provides a bacterium comprising a phosphate butyryltransferase (Ptb) and a butyrate kinase (Buk) (Ptb-Buk) that act on non-native substrates to produce a wide variety of products and intermediates. In certain embodiments, the invention relates to the introduction of Ptb-Buk into a C1-fixing microoorgansim capable of producing products from a gaseous substrate.

Swedish Biofuels AB, as the co-ordinator of a broad ranging international consortium, proposes the construction of a pre-commerical demonstration plant for the production of fully synthetic paraffinic jet fuel from wood and other biomass. The consortium is to design, construct, commission and operate the plant, which will take a variety of raw materials and produce jet fuel that is compatible, without blending, with in-service and envisaged jet engines for both military and civilian applications. The plant capacity is 10,000 t/y of fuel, of which 5,000 t/y fully synthetic paraffinic jet fuel, the rest is diesel and aviation gasoline. The plant is based on technology that has been developed by Swedish Biofuels and LanzaTech, which. has been validated by the United States Air Force (USAF) and the United States Federal Aviation Authority (FAA). The technology has been granted patent protection in Europe the USA and the other major markets of the world. The plant, in the main, uses standard equipment. The non-standard equipment, roughly 10 % of the total, is to be manufactured by AS Remeksi Keskus. The plant is to be constructed in Sweden on a site owned by Perstorp Bioproducts AB, the wood raw materials to be supplied by SCA Energy AB. The fuel will be used by Deutsche Lufthansa AG for flight tests. When the fuel is available it will used by Saab as part of a Sweden national study involving the Swedish jet fighter Gripen. All products from the plant, jet fuel, diesel and aviation gasoline will be marketed by SkyEnergy BV. The raw material base for the demonstration plant will be extended during the project by 1) the introduction of ethanol produced from municipal solid waste by Abengoa Bioenergia Nuevas Tecnologias SA 2) the use of biogas for the production of syngas by Perstorp. This will improve the plant economics and environmental impact, as will be investigated by E4Tech SARL during the project.

The proposed STEELANOL project is based on producing bioethanol via an innovative gas fermentation process using exhaust gases emitted by the steel industry. The proposal addresses the specific topic Demonstrating advanced biofuel technologies (LCE-12 2014), under the call for competitive low-carbon energy in Horizon2020. The BF/BOF gaseous emissions are an unavoidable residue from the steelmaking process and are currently used for electricity production or being flared. Nevertheless, they can be advantageously used to produce bioethanol, thereby reducing the usage of fossil fuel molecules and thus significantly reducing GHG emissions. The bio-ethanol production would have a GHG impact that is over 65% lower compared to oil derived fuels STEELANOLs main objective is to demonstrate the cost-effective production of sustainable bioethanol, with the purpose of assessing the valorisation of this ethanol biofuel as a fuel derivative for the transport sector. A demonstration plant of approximately 25,000 tons/ethanol per year will be built; the first of its kind in Europe, and the largest facility built to date utilizing this technology globally. ArcelorMittal is the lead partner of this project and proposal. The gas fermentation technology will be supplied by LanzaTech, the engineering work will be performed by Primetals, and E4Tech will develop the Life Cycle Assessment of the produced fuels. Several key players in the transport sector, Boeing, Virgin Atlantic, Mitsui, have expressed their strong interest and support for the project.
