CFU counts (▲) of S. yanoikuyae B1 growing on naphthalene (■) at different pressures. S. yanoikuyae B1 was cultivated at room temperature. The CFUs were counted after an incubation time of 70 h and determined in triplicate. Standard deviations are shown. The dashed line indicates the starting naphthalene concentration (▬ ▬ ▬), the stippled line is the starting cell number (● ● ●) at 0 h.
