“…It has been reported that the non-metal graphitic carbon nitride (g-C 3 N 4 ) has been combined with Ralstonia eutropha for bioplastic production under light irradiation (Xu et al, 2019). This proof-of-concept study illustrated that the inorganic photocatalysts could also enhance the productivity of the cellbased hybrid system with good biological compatibility.…”

Klebsiella pneumoniae with crude glycerol-utilizing and hydrogen (H2)-producing abilities was successfully isolated from return activated sludge from Shatin Sewage Treatment Works. The H2 production strategy used in this study was optimized with crude glycerol concentrations, and 1,020 μmol of H2 was generated in 3 h. An inorganic–microbe hybrid system was constructed with metal-free hydrothermal carbonation carbon (HTCC) microspheres to enhance the H2 production under visible light (VL) irradiation. Under optimized VL intensity and HTCC concentration, an elevation of 35.3% in H2 production can be obtained. Electron scavenger study revealed that the photogenerated electrons (e–) from HTCC contributed to the additional H2 production. The variation in intercellular intermediates, enzymatic activity, and reducing equivalents also suggested that the photogenerated e– interacted with K. pneumoniae cells to direct the metabolic flux toward H2 production. This study demonstrated the feasibility of using an inorganic–microbe hybrid system as a waste-to-energy technology.

“…In the absence of any sacrificial electron donor, R. eutropha-g-C 3 N 4 improved the PHB production by 1.2 times and with triethanolamine as an electron donor, the production was enhanced by 1.4 times compared with pure R. eutropha. Furthermore, the ratio of intracellular reductase NADPH/NADP was increased in the hybrid system due to facile energy metabolism [68]. Tremblay and collogues further improved the PHB production potential of R. eutropha-g-C 3 N 4 by coupling g-C 3 N 4 with H 2 O 2 -degrading catalase [69].…”

“…23,24 These use non-enzymatic photocatalysts which exhibit high solar-to-chemical energy conversion 24 and have shown biocompatibility with various microorganisms. 25 Seminal studies from Torella and coworkers and Liu and co-workers demonstrated the use of bioelectrochemical cells containing R. eutropha to produce PHB and fusal alcohols from CO 2 and H 2 O. 26,27 Using a reactive oxygen species (ROS)-resistant Co-P alloy cathode, the authors achieved CO 2 reduction efficiencies exceeding that of natural photosynthesis.…”
