The maximum biomass concentration of 0.91 g dcw/L was obtained with an aeration rate of 0.75 vvm, a light intensity of 300 μmol m-2 s-1, and a photoperiod of 24:0 h. The maximum lipid production of 51.8% (w/w) was obtained with a light intensity of 400 μmol m-2 s-1 and a photoperiod of 18:6 h. Additionally, the eicosapentaenoic acid and unsaturated fatty acid contents reached 30.6% to 56.2% at pH 6.0. Epub 2019 May 20.
