Substrate competition between methanogenic consortia and sulfur/nitrogen compounds metabolizers. a MP: 37 °C; AP: 20 °C. Green arrow lines implicate syntrophic phenol-degrading methanogenic pathway. Blue arrow lines indicate pathway competition for methanogenic substrates and other organic molecules. APS adenosine 5′-phosphosulfate, GSB green sulfur bacteria Chlorobiaceae. b Percent in heatmap cells denotes relative abundance (%) of each genome in a metagenome
