Fig. 3From: Genomics and prevalence of bacterial and archaeal isolates from biogas-producing microbiomesOverview of the four phases of the conversion of biomass into biogas and allocation of the analyzed microbial strains to the different conversion steps. Functional roles of the organisms were determined considering relevant KEGG pathways, namely the propionic acid, ethanol, formic acid, butyric acid, and lactic acid fermentationBack to article page
