Abstract

The process according to the invention for the microbial production of a specific product and methane comprises the following steps: a) the production in a bioreactor (2, 10) of a specific product from a specific substrate using a specific organism, the producer, wherein during the production of this product metabolites such as e.g. low-molecular alcohols, aldehydes and acids, hydrogen and CO2, which may inhibit the production of the product, are obtained; and b) the production of methane by means of a methanogen, wherein in the production of the methane at least one metabolite is decomposed and by this means removed from the bioreactor (2, 10) and its energy is made usable.
