FeS2 was added to a final concentration of 2 mM Fe. The cell density was determined after 5 days. Data shown are the mean values for each condition with error bars reflecting the standard deviation of three replicate biological reactors. CH4, methane; HS−, sulfide. See Supplementary Table 3 for data used to generate the plot.
