Methanogenesis pathway predicted in our fermenter based on the KEGG analysis. The ellipses denote the substances involved in the reaction. The boxes show the enzymes involved in methanogenesis. The acetotrophic (green), the hydrogenotrophic (blue), and the shared pathways (grey) are all color-encoded and the color depth indicates the amount of reads assigned. The enzymes that are potentially associated with Anaerococcus and Psychrobacter in the methanogenesis pathway are shown in the yellow box.
