In the upper part of the table are reported PGs potentially classified as SAOB or homoacetogens; in the lower part of the table are reported the syntrophic PGs (propionate and butyrate degraders). Asterisks indicate statistically significant number of genes in a specific PG in comparison with other genomes (1,000 random sampling process as explained in Methods section; p-values are reported in Supplementary Data 4). The presence of formate dehydrogenase (fdhF) gene in the PGs is also included. Abbreviations: Prop (propanoate metabolism), But (butanoate metabolism), CFP (carbon fixation pathways), FAD (fatty acids degradation), WL (Wood–Ljungdahl pathway), TCA (TCA cycle), fdh (formate dehydrogenase), ISA (inorganic sulfur assimilation), Me (menaquinone). In the second and third column are reported the ratio (log₂) of the PGs abundance after H₂ addition vs. before H₂ addition in thermophilic (thermo) and mesophilic (meso) conditions.
