Fig. 7. Comparison of growth performance and biomass accumulation of marine strains under presence of 5% (v/v) CO₂.

Strains were grown in triplicates at 30 °C, 250 rpm shaking under continuous illumination using RGB LED 1:1:1 ratio. Synechococcus sp. PCC 11901 and PCC 7002 were grown in the MAD and MAD2 medium at initially 150 µmol photons m⁻² s⁻¹, which was then increased to 750 µmol photons m⁻² s⁻¹ after 1 day. Data points with error bars represent mean of n = 3 biological replicates ± standard deviation. a, b Growth curve and biomass accumulation comparison of PCC 11901 and PCC 7002 strains in MAD and MAD2 medium. c Continued growth curve and biomass accumulation of PCC 11901 strain cultured in MAD2 medium for 14 days.
