Core community. The top 20 core biological processes (a), as well as the top 20 core metaproteins (same UniRef50) (b) are shown, based on the number of identified spectra and the median over all BGPs. Calculations of the error bars were carried out using the standard deviation of each metaprotein (resp. biological process), calculated for all BGPs. Additionally, for all profiles, the core elements identified in all BGP are shown in light red and labeled with the associated minimum value. Unlabeled and dark red bars indicate that these biological processes resp. metaproteins were not observed in all BGPs. Two different types of S-layer protein and flagellin were identified in the samples. GAPD glyceraldehyde-3-phosphate dehydrogenase, H 4 MPT tetrahydromethanopterin, MCR methyl-coenzyme M reductase
