Figure 2: (A) Transmission electron micrograph of R. eutropha H16 cells containing PHA granules. (B) Schematic repres entation of a PHA granule in R. eutropha. Enzyme designations: PhaR = Regulator of PhaP expression; PhaP = Phasin protein; PhaC = PHA synthase; PhaZ = PHA depolymerase; PhaM = New DNA-binding, granule associated protein, as described in [22]. (C) Fluorescent micrograph of R. eutropha Re2058/pCB113 [24] grown for 24 h in minimal (PHA production) medium with palm oil as the sole carbon source [43]. P(HB-co-HHx) granules are stained with Nile red.
