Abstract: Disclosed is a process method for producing a single cell protein comprising the steps of (a) providing gaseous hydrogen (H2); (b) mixing the hydrogen gas from step (a) with a carbon source, to provide a C1 compound, such as methane, methanol, formaldehyde, formic acid, methanethiol, or methanesulfonic acid, or derivates thereof; (c) adding or passing the C1 compound provided in step (b) to a loop reactor comprising one or more microorganisms capable of metabolizing the C1-compound providing an inoculated fermentation medium; (d) allowing the inoculated fermentation medium to ferment, in a fermentation process, and converting the C1 compound into a biomass material; and (e) isolating the biomass material provided in step (c) and providing the second single cell protein, wherein the carbon source is gaseous carbon monooxide (CO); gaseous carbon dioxide (CO2); or a combination hereof, or wherein the first carbon source is an aqueous solution of carbon dioxide, such as carbonic acid or a hydrogencarbonate or car

Abstract: A system and a method is disclosed for adjusting and/or optimizing a fermentation process performed in one U-loop fermenter, the system including a processor and database for repetitively providing a test value of a fermenter parameter and for repetitively entering the test value of the parameter in the database; wherein the database stores multiple test value entries at various points in time and also stores multiple control value entries at various points in time, wherein the processor performs a mathematical analysis of the test value for providing a calculated test value, and/or the control value for providing at least one calculated control value; and selects, on the basis of the calculated test value and/or on the calculated control value, an adjustment to be introduced into at least one other U-loop fermenter to benefit from the change made in the one U-loop fermenter.

Abstract: The present invention relates to a method for providing a fermentation medium for the cultivation of at least one methanotrophic organism, or for the cultivation of a combination of organisms comprising at least one methanotrophic organism, the method comprises the step of: (i) providing a main growth solution; (ii) optionally sterilizing the main growth solution provided in step (i); (iii) providing a trace metal solution; and (iv) mixing the main growth solution (as provided in step (i) or (ii)) with the trace metal solution provided in step (iii) and providing the fermentation medium for the cultivation of at least one methanotrophic organism, or for the cultivation of a combination of organisms comprising at least one methanotrophic organism.

Abstract: A method for improving biomass production and/or growth rate of a microorganism in a fermentation process is shown, and includes: (i) providing one or more microorganisms; (ii) providing a fermentation substrate suitable for fermenting the one or more microorganisms; (iii) mixing the one or more microorganisms and the fermentation substrate providing a fermentation broth; (iv) adding the fermentation broth to a fermentation tank; (v) injecting at least one gaseous substrate into the fermentation broth; (vi) running the fermentation process for a fermentation period of at least 1 hour; wherein the at least one gaseous substrate comprises one or more greenhouse gases, such as carbon dioxide (CO2).
