Method P.119 right column bottom paragraph: "[Investigators] used the cultivation set-up described above to test specific growth-rate dependent responses of Synechocystis. [They] ran a total of 39 completely independent (parallel) photonfluxostat cultivations at different growth rates by varying the light intensity per OD720."
Comments P.120 right column: "Regarding the biomass yield on photons (Y'x/h), [investigators] found it to be 0.876 gDW/mol photons. Given the uncertainties surrounding how much photons are actually absorbed by cells depending on light sources and experimental set-ups [primary source 27], [they] consider this value to be comparable with the value obtained in this study using turbidostat data [0.628 gDW/mol photons (Fig. S4)], and with previous reports based on data from continuous cultivations of Synechocystis: 1.237 gDW/mol photons [primary source 25] using “cool-white” LED light and 1.724 gDW/mol photons [primary source 28] using red monochromatic light (659 nm, half width 16.3 nm)."
