Growth rate and oxygen evolution of the strains in this study under photoautotrophic and photomixotrophic conditions^a

Strain	Doubling time (h) during growth		Oxygen evolution rate (μmol of O2 mg of chlorophyll−1 h−1)
	Photoautotrophic	Photomixotrophic
Wild type	12.8 ± 0.4	12.7 ± 0.6	256 ± 28
T192H	NGb	13.5 ± 0.8	0
Rg2	13.3 ± 0.5	13.8 ± 0.7	275 ± 35
T192T/Y294Stop	13.4 ± 0.7	13.5 ± 0.6	248 ± 32
PS I-less	NG	22.3 ± 1.1	—c
Rg2/PS I-less	NG	24.1 ± 0.9	—

^aNumbers represent the mean calculated from three independent experiments ± the standard deviation.

^bNG, no growth (strain does not grow under these conditions).

^c—, not measured.
