Supplementary Figs A and B. Electron micrographs of negatively stained cells (A) and thin-section (B) of strain C55T. Bars, 0.5 µm (A), 0.2 µm (B).

Supplementary Figs C–E. Effects of temperature (C), pH (D) and Na+ concentration (E) in TSmj medium on the growth of Thiobacter subterraneus strain C55T. Growth curves at different temperatures were determined in TSmj medium at pH 6.5. The effect of pH on growth was determined at 55 °C over a range of pH values. The pH was adjusted to various levels at room temperature. The effect of Na+ concentration on growth was determined in variously diluted or concentrated TSmj media. [PDF] (60 KB)
