Abstract :

In this present investigation an attempt was made to study the Bicarbonate tolerance of selected micro algal strains (Scenedesmus sp. Botryococcus sp. and Euglena sp.). The three microalgal strains were collected from the Presidency College, Chennai, India. These strains were grown in different molar concentrations of NaHCO₃ in two different medium BBM and BG11 without any changes in other substances of media. The Optical density (OD) was measured at regular interval time of 24hrs at 680nm employing UV-Vis Spectrophotometer. Growth rate and Biochemical composition were investigated in this study. All the three microalgal strains were grown well in the 0.1 molar concentration of NaHCO₃ in both BBM and BG11 media but the best growth rate was showed in BG11 media when compared to BBM. The highest growth rate was seen in Euglena sp. and lipid content was found high in Botryococcus sp. at 0.1 molar concentration of NaHCO₃.
