Fig. 3From: Heterologous mannitol-1-phosphate dehydrogenase gene over-expression in Parachlorella kessleri for enhanced microalgal biomass productivityGrowth study and nitrate uptake profile of transformed and wild-type P. kessleri under natural light of 0–1200 μmol photons m−2 s−1. Values are mean ± standard deviation (n = 3). Student’s t test was significant at P < 0.05 except for nitrate content which was significant at P < 0.09Back to article page
