Competitive growth of bkt5 with UVM4 and Chlorella vulgaris. A, B Picture taken at the end of the growth in the case of cells grown in TAP (A) of HS (B) media of UVM4 (black), bkt5 (red) or a mix of the two genotypes in equal amount (blue), at 3000 μmol photons m−2 s−1 as reported in Fig. 6. C, D Spectra of the pigments extracted at end of the growth in TAP (C) of HS (D) experiment; spectra are normalized to the Qy absorbance. The inset shows the calculated percentage of bkt5 cells inside the mix tube. (E) Picture taken, at the end of the growth at 3000 μmol photons m−2 s−1 of bkt5, C. vulgaris (Cv) and a mix of the two genotypes. Tubes on the left side of the black line show the result of competition test starting from the same number of cells. Tubes on the right side show the result of mix starting from the same chlorophyll amount. F, G Spectra of the pigments extracted from the tubes of bkt5 (black), Cv (red) and the mix (blue) at the end of experiment starting from the same number of cells (F) or the same Chl amount (G). Spectra are normalized to the Qy absorbance. Insets show the calculated percentage of bkt5 cells inside the mix tube
