Effect of Alkali Metals Ions on Growth and Biomass Accumulation of Lipid (Metabolism) in Chlorella Vulgaris

In this paper, we analyze the influence of nutrient medium on the growth of algae biomass species Chlorella vulgaris. By employing methods of microscopy, one- and two-dimensional thin layer chromatography, as well as by using mathematical methods of interpolation and approximation of data, we show that reduction of nitrogen concentration, increase of salinity and concentration of potassium drastically decrease the biomass growth. The amount of lipids increases to 10–15 % under nitrogen deficiency, moderate salinity (2,5 g/l NaCl) and in the joint action of both factors.
