FIG 2.

Allylthiourea (ATU) sensitivity of Rhodococcus sp. ZPP for growth on ethane and propane (OD₆₀₀). For all substrates, data are the averages from three independent experiments, and upper error bars indicate the standard deviations. Lower error bars are not shown in order to avoid overlapping error bars. For these experiments, 1,000-fold-diluted washed cells were used. Gases were replaced after approximately 2 days to maintain sufficient gas concentrations for exponential growth.
