Figure 2From: Identification and characterization of the intracellular poly-3-hydroxybutyrate depolymerase enzyme PhaZ of Sinorhizobium melilotiBacteroids of Rm1021 (A) and Rm11430 (B). Electron-transparent PHB granules are clearly visible in bacteroids of Rm11430. PHB granules in the cytoplasm of the Rm11430 bacteroids are indicated in panel B. These granules are notably absent in the bacteroids of Rm1021 shown in panel A. Scale bar: 2 μ m.Back to article page
