FIGURE 4.
Gas compositions (CH4, O2, and CO2) in headspace during the 14-day incubation of M. tundripaludum SV96 (left column) and M. rosea SV97 (right column) under three different gas supplementation schemes applied on day 7: (test I) both CH4 and air added (A,D), (test II) only CH4 added (B,E), and (test III) only air added (C,F). Error bars indicate the standard deviation of triplicate samples.
