The prediction plots of “Design of Experiment”. The solid line represents the predicted value, while the dashed line represents the upper and lower limits of the confidential interval (95%). a, d, g The predicted responses of fucoxanthin content, fucoxanthin productivity and power input to light source, respectively, at 100 μmol/m2/s and 18/6 light regime; b, e, h the predicted responses of fucoxanthin content, fucoxanthin productivity and power input to light intensity, respectively, at 18/6 light regime with blue LED light; c, f, i the predicted response of fucoxanthin content, fucoxanthin productivity and power input to light regime, respectively, at 100 μmol/m2/s with blue LED light. Lowercase letters indicate statistical differences
