Comparison of the initial pentadecane formation rate using WLEs for internal illumination (▪) and a LED for external illumination (•) at different light intensities. Conditions: [palmitic acid]₀=13 mM; [rec. E. coli]=50 g L⁻¹ ([CvFAP]=6 μM); buffer: 100 mM Tris‐HCl (pH 8.5), 30 % v/v DMSO, volume=50 mL; T=20 °C. The variation of the internal illumination light intensity was achieved by addition of different numbers of WLEs while for external illumination this was realized by changing the driver current.
