Histograms of a µmax, b MERmax, and c qCH4 max at each experimental condition applied in this study. M. maripaludis was grown at 37 °C, 140 rpm, 2.9 bar. Ac and Pr stand for acetate and propionate, respectively. The values 1, 2, 3 refer to the increasing concentrations of each compounds applied individually and simultaneously. (1,2,3) Zn: 1.0, 2.4, 3.9 mmol L−1; (1,2,3) Cu: 1.9, 4.4, 6.3 µmol L−1; (1,2,3) Ac: 12.2, 60.9, 121.9 mmol L−1, (1,2,3) Pr: 10.4, 52.0, 104.1 mmol L−1, 0Ac: without acetate
