H2 and H2S consumption and growth by Hydrogenobaculum strain 3684. (A) Time course consumption assay. Dissolved H2 after the addition of autoclave-killed YNP3684 cells is shown by open circles (○), dissolved H2S after the addition of autoclave-killed YNP3684 cells is shown by open squares (□), dissolved H2 after inoculation with 2 × 106 cells ml−1 is shown by filled circles (•), and dissolved H2S following inoculation with 2 × 106 cells ml−1 is shown by filled squares (▪). (B) Growth of isolate YNP3684. H2 (726 nM) is shown by filled circles (•), 30 nM H2 + 60 μM H2S is shown by filled squares (▪), 60 μM H2S is shown by open squares (□), and 30 nM H2 is shown by open circles (○). Data are the means of triplicate samples. Error bars represent one standard deviation.
