FIG. 3.

Sulfide production (●) and increase in cell turbidity (○) in a culture of strain oXyS1 growing in defined medium on o-xylene. The growth experiment was carried out in a flat bottle (500 ml) with 450 ml of medium and 0.3 ml of o-xylene dissolved in 15 ml of heptamethylnonane. The bottle was incubated horizontally and shaken slightly. OD, optical density.
