摘要：
The present invention relates to a fermentation process for the fermentation of at least one microorganism, wherein the fermentation process comprises the steps of (a) allowing a fermentation broth comprising the at least one microorganism to flow in the fermentation reactor; (b) supplying a carbon-substrate to the fermentation reactor allowing the gaseous carbon-substrate to be dissolved, or partly dissolved, in the fermentation broth; (c) supplying a nitrogen-substrate to the fermentation reactor allowing the gaseous nitrogen-substrate to be dissolved, or partly dissolved, in the fermentation broth; and (d) maintaining a nitrate concentration of the fermentation broth below 0.035 g/l, and/or maintaining a nitrate concentration of the fermentation broth below 0.01 g nitrate/g biomass; wherein the at least one methanotrophic organism comprises at least one methanotrophic microorganism.
