In this study, the Antarctic microalgae Chlorella variabilis YTU.ANTARCTIC.001, was cultivated at different temperatures of 4, 13, 20 and 27 °C in modified BG-11 medium with various concentrations of NaNO3 (0, 0.75, 1.5, 2.5 and 3 g L−1) under three photoperiods (8:16, 16:8 and 24:0) to investigate the growth and biochemical compositions. The specific growth rate changed from 0.012 to 0.23 day−1 with an increase in nitrate concentration, temperature and light cycle. The highest specific growth rate was 0.23 day−1 using the growth medium that consisted of 3 g L−1 nitrate at 27 °C under 16:8 h light–dark cycle, while there was no algal growth at 4 °C. Carbohydrate, protein, chlorophyll-a and β-carotene contents of microalgae increased with the increasing concentrations of nitrogen at 20 °C and 27 °C. The highest lipid content was achieved as 66% DW, using the growth medium consisting of 0.75 g L−1 nitrate at 13 °C.
