Figure 1.

Repetitive batch growth of P. putida F1 in a bioreactor using a) benzoate or b) citrate as the sole carbon and energy source (cell growth was followed by measuring optical density at 600 nm, CO₂ production and O₂ consumption). Arrow indicates the sampling time for proteomic analyses. The specific growth rates derived from the exponential phase for each growth cycle in c) benzoate or d) citrate are also shown.
