Figure 4

Individual cell of R. eutropha H16 with constitutive over-expression of PhaM after 1 h of PHB permissive conditions. Three invaginations of the cell wall (= 4 cells) are a visible indication that the last two cell-divisions have not been finished. All preparations were performed as described in legend to Figure 1. Note, presence of four individual, well-separated clusters of PHB granules apparently each bound to the nucleoid regions of the division-inhibited cell. Bar 0.5 μm.
