Fig. 2From: Disruption of poly (3-hydroxyalkanoate) depolymerase gene and overexpression of three poly (3-hydroxybutyrate) biosynthetic genes improve poly (3-hydroxybutyrate) production from nitrogen rich medium by Rhodobacter sphaeroidesVolumetric PHB production, DCW, and PHB content of the HJ (pLP-1.2) and HJΔphaZ (pLP-1.2) strains. a Volumetric PHB production during a 5 day culturing time; b DCW after 5 days of incubation; c PHB content after 5 days of incubation. Cells were grown anaerobically at 30 °C under illumination at 8.2 W m−2 for 5 days. Three independent fermentation experiments were done. Data are presented as the mean ± standard deviation (n = 3)Back to article page
