Graphic representation of the GBs abundance in the biogas microbial community. The GBs coverages are represented as circles where the area is proportional to the coverage. GBs are grouped considering the taxonomic assignment at phylum level (Sp Spirochetes, Sy Synergistetes, Th Thermotogae, Pr Proteobacteria, Fi Firmicutes, Te Tenericutes, Ac Actinobacteria, Ba Bacteroidetes, Tm TM7 phylum, Eu Euryarchaeota). Outlines colors correspond to those reported in Fig. 1
