Fig. 3From: Assessing methanotrophy and carbon fixation for biofuel production by Methanosarcina acetivorans Acetate and carbon dioxide production yields as a function of bicarbonate to methane ratio (a, b) and biomass yield (c, d) using Fe3+ (solid lines) or SO4 2− (dashed lines) as external electron acceptors. Methane was the sole carbon source for generating the plots shown in panels (c) and (d). All yields are per 10 mmol of methaneBack to article page
