Fig. 2. Hydrogen photosynthesis by the E. coli cell–CdS hybrid system.
(A) Detailed diagram of an engineered E. coli cell. (B) TEM images of biosynthesized CdS nanoparticles on the surface of an engineered E. coli cell. (C) EDX confirmation of randomly chosen CdS nanoparticle. (D) H2 production by the hybrid system under anaerobic conditions. (E) Changes in the rate of H2 production by the hybrid system during irradiation. SDs represent the averages of three independent experiments. CFU, colony-forming units.
