Extended Data Fig. 2: Sulfide production in anoxic C5-C12 n-alkane-degrading cultures at 70 °C up to the third dilution.
Each culture was set up as a duplicate. Gaps in sulfide level indicate dilution steps. Pink arrows indicate the sampling points for metagenome and -transcriptome sequencing. Samples were collected after the third dilution from cultures degrading (a) n-pentane, (b) n-heptane, (c) n-octane, (d) n-nonane, (e) n-decane, and (f) n-dodecane. The negative control (light gray line) consisted of a sediment slurry without added substrate.
