(a) Growth curves of TAG-1 (○, ●) and SV-108 (□, ▪) on H2 (○, □) or FeCl2 (●, ▪) with ammonium chloride (upper, n=3) or sodium nitrate (lower, n=2). Hydrogen and Fe(II) sources were regularly fed. Growth curves with neither H2 nor Fe(II) source (with ammonium chloride) were also shown. (b) Monitoring of hydrogen concentrations (upper) and cell numbers (lower) in strain TAG-1 (○) and SV-108 (□) cultures (n=3). Additional H2 was fed after 144 h (TAG-1) and 168 h (SV-108) of incubation. Error bars indicate standard deviations.
