The present study was carried out to find out influence of different NaCl concentration (0.04 M-0.34M) in the growth of the freshwater microalga Ankistrodesmus falcatus and its biochemical constituents viz. lipid, protein, carbohydrate and secondary pigment viz chlorophyll. There was considerable variation in growth as well as biochemical constituents of the microalga with varying concentration of NaCl. Highest increase in lipid content was found to be in 0.17 M NaCl, however protein and carbohydrate content was enhanced in 0.34M NaCl, but there was a decrease in chlorophyll content with increasing concentration of NaCl. The changes in growth and biochemical constituents indicated the influence of salinity and organism’s adaptability to the tested levels of salinity.


Key words: Microalgae, lipid, Chlorophyll, Salinity.
