Fig 2.

Conversion of CS₂ by five A. thiooxidans strains. The arrows indicate the times when 17 μM CS₂ was injected into a cuvette containing cells from a continuous culture growing at D = 0.02, diluted 6× in MM containing 1% H₂SO₄. Respiration (O₂ consumption, black dashed line), H₂S production (black solid line), and S⁰ production (gray line) were monitored. The production and consumption rates in these graphs were used to determine the percentages of S⁰ accumulation in Table 2. Note the different scale on the x axis of the graph for strain Sts 4-3.
