Heterotrophic Hybrid Photosynthesis with g-C₃N₄-Catalase and R. eutropha

(A and B) (A) PHB production and fructose consumption over time and (B) PHB concentration after 96 h.

(C and D) (C) Scanning and (D) transmission electron micrographs of R. eutropha grown with g-C₃N₄-catalase under heterotrophic conditions. R. eutropha cultures were grown at 30 ⁰C in minimal medium with 20 g L⁻¹ fructose in the presence or absence 0.5 g g-C₃N₄ and/or 5,000 U mL⁻¹ bovine liver catalase. Where indicated, cultures were incubated under 4,200-lux LED light. Each curve and bar is the mean of at least three replicates with standard deviation.
