Methanogenesis chemical equation

WebMethanogenesis. Since 2012 Krajete optimizes the process of biological methanation by harnessing the power of naturally occuring microbes, namely archaea. These smart little creatures are able to form methane (CH4) by consuming only hydrogen (H2) and carbon dioxide (CO2). In fact. the basic reaction of the archaea is analogous to the chemical ... Methanogenese is de vorming van methaan door bepaalde micro-organismen. Methanogenese treedt op wanneer biomassa in zuurstofloze condities wordt afgebroken. De productie van methaan is een belangrijke en wijdverspreide vorm van microbiële stofwisseling. Methanogenese is verantwoordelijk voor een groot deel van het aardgas dat in de bodem voorkomt. De rest ontstaat thermogeen.
