Fig. 2From: Reducing self-shading effects in Botryococcus braunii cultures: effect of Mg2+ deficiency on optical and biochemical properties, photosynthesis and lipidomic profileScores plot for a principal component analysis (PCA) of B. braunii cells cultivated under different Mg+2 regimes. PC 1 and PC 2 explain the 55.3% and 17.8% of variation, respectively (cumulative 73.1% of variation explained by the model)Back to article page
