Key functional genes involved in carbon and energy metabolism that are present (red) in MAGs. Abbreviations: cytochrome bd terminal oxidase (Cytochrome bd), Cbb3-type cytochrome c oxidase (Cytochrome cbb3), nitrite oxidoreductase (Nxr), membrane bound nitrate reductase (NarG), nitrite reductase (Nik), nitrous oxide reductase (NosZ), dissimilatory sulfite reductase subunit A (DsrAB), Methyl-coenzyme M reductase (McrA), Embden-Meyerhof pathway (EMP), pentose phosphate pathway (PPP), pyruvate dehydrogenase (PDH), pyruvate:ferredoxin oxidoreductase (PFR), pyruvate formate lyase (PFL), Lactate dehydrogenase (LDH), Acetyl-CoA synthetase (Acs), phosphate acetyltransferase (Pta), and acetate kinase (Ack). Note: The CO2 fixation refer to the presence of genes involved either in reductive TCA cycle or Wood–Ljungdahl pathway and glycogen utilization pathway indicates that glycogen phosphorylase and glycogen debranching enzyme were identified in the genome. The MAGs highlighted in blue represent the potentially living microbial populations inferred from DNA damage in both iDNA and eDNA fractions
