The rapid population growth, fast agricultural extensions, increased urbanization and industrialization have together stressed the exploration of eco-friendly sustainable and renewable energy resources in meeting the energy needs. Biodiesel is a fuel that comprises mono-alkyl esters of long-chain of fatty acids derived from vegetable oils. Microalgae have tremendous capacity of biosynthesis of TAG compared to other terrestrial crops. The aim of present work was to study effect of various nitrogen sources on the patterns of microalgae growth and the lipid content. The two cultures selected were Chlorella pyrenoidosa NCIM 2738 recognized culture by NCIM, and ANK-1 a culture collected from Ankleshwar in Gujarat. According to morphological study under microscope ANK-1 was identified as Chlorella sp. various nitrogen sources used were ammonium sulphate, urea and potassium nitrite in BG-11 and Bolds and Basal medium. The objective is to monitor the change in the growth pattern subsequently the lipid content under different medium. The study confirms the impact on growth and lipid content while changing the source of nitrogen wherein; BG-11 medium containing nitrogen sources like ammonium sulphate, urea and potassium nitrite resulted in good growth in Chlorella pyrenoidosa whereas, the medium containing urea proved good in case of ANK-1.
