Abstract
The invention provides a process for producing hydrogen and methane gases by microbial fermentation. The process involves a first reactor in which a fermentation produces hydrogen and a liquid effluent. The liquid effluent is fermented in a second reactor to produce methane. The ratio of hydrogen to methane produced is adjusted by adjusting the liquid volume of the first reactor.
