Phylogenetic distribution of Methanocorpusculum MAGs and isolate genomes. A Concatenated archaeal marker gene files were produced using GTDB-Tk (v.1.3.0) [29], with Methanomicrobium mobile BP used as the outgroup. Phylogeny was inferred using FastTree (v2.1.10) [30] and visualisation by iToL (https://itol.embl.de/). MAGs and isolate genomes of ≥ 50% completeness and ≤ 10% contamination were included, and HQ MAGs were identified by blue circles. Cultured isolates were identified by a red star. Bootstrap values are shown by the red (≥ 0.7) and black (≥ 0.9) circles. All MAGs and isolate genomes from environmental sources were identified as ‘environmental’ under the host description.
