A–C The congo red degradation assay with or without blue light irradiation in the CdS- or InP-biohybrid system. D, E NADH regeneration in NOX overexpressing strain under the dark or blue light conditions. F Butyrate titer with CdS-biohybrid system under the blue light or dark conditions. G Fluorescence activation with different stationary phase promoters. H Fluorescence activation with different stationary phase promoters through flow cytometer analysis. I Comparing the CdS nanoparticle concentration with different conditions. J Comparing the pyruvate/L-malate and NADH value with different conditions. K L-malate production with the engineered E. coli M6 controlled by light irradiation during 3.6 L fed-batch fermentation. L L-malate production in the 3.6 L fermenter with two-stage fermentation.
