	Lab-scale, indoor PBR		Outdoor PBR
Genotype	Mean increase of biomass (g L^-1day^-1)	μ (day^-1)	Mean increase of biomass (g L^-1day^-1)	μ (day^-1)
WT	0.29 ± 0.01	1.28 ± 0.05	0.22 ± 0.02	1.25 ± 0.04
TAM-2	0.38 ± 0.01*	1.39 ± 0.03*	0.28 ± 0.03*	1.33 ± 0.04*
TAM-4	0.30 ± 0.02	1.30 ± 0.03	0.18 ± 0.03	1.25 ± 0.06

Biomass increase was measured in both lab-scale and outdoor photobioreactors, by the determination of dry biomass accumulated after the cultivation period, divided by the number of days of cultivation. μ, the specific growth rate, was calculated from the slope of the logarithmic cell concentration curve. Data are expressed as mean ± SD, n = 6. Significant different values (Student’s t-test, P <0.05) are marked with an asterisk.
