Growth and ethanol production assay of strains with diverse PDCzm-slr1192 ratios. a Total carbon productivities and carbon partitioning ratio to ethanol of PCC6803, Syn-ZG25, Syn-HZ24, and Syn-YQ4, taking NaHCO3 as carbon source. Carbon distributed to ethanol and biomass was calculated by measurement of ethanol concentration and OD730. Numbers in the bars percent of total fixed carbon distributed to ethanol, numbers above the bars the actual ethanol concentration synthesized by the strain (g/l/day). b Growth and c ethanol production of the three strains cultivated in column photo-reactor system
