Carotenoid composition of P. boryanum cells grown at 29 and 15°C

Carotenoid	Result under the following growth conditionsa
	Optimal (29°C/150 μmol m−2 s−1)	ELLT (15°C/150 μmol m−2 s−1)
Myxoxanthophyll	0.101 ± 0.015	0.484 ± 0.051
Zeaxanthin	0.035 ± 0.007	0.074 ± 0.012
β-Carotene	0.249 ± 0.009	0.329 ± 0.059

^aResults are micromolar concentrations per micromolar chlorophyll. Mean values ± standard errors of the means were calculated from three to four independent experiments with three separate measurements in each experiment.
