Use of biomagnetism for biogas production with a recirculation of fermentation broth

Abstract

The invention relates to a method for producing biogas. An organic substrate and an enzyme are provided for this purpose. In addition, fermentation broth from a fermenter is recirculated to the enzyme and substrate to form a fermentation broth-enzyme-substrate complex. The fermentation broth-enzyme-substrate complex is exposed to a magnetic field and then returned to the fermenter.
