The PHB granules appear before the first cellular division. A Mid-exponential phase cells. B Late stationary phase cells, used as inoculum (T₀) for the second time-series experiment. T₁ Cells after 30 min of shaking at 34 °C and 300 rpm. The microscopy images of T2, T3 and T4 samples are not shown in Fig. 2 because they are very similar to the T1 sample. The scale bar is 1 µm
