Abstract: The present investigation was aimed to study reciprocal response of nitrogen to enhance the cell multiplication and proximate balance from marine microalgae Tetraselmis sp. under low saline conditions. The strain has been isolated from Yellow Sea, South Korea and the algae were cultured in the different nitrogen concentrations (0N, 1N & 2N) under low saline conditions (15, 20 and 25 psu).The results revealed that the Tetraselmissp. have significantly higher (P < 0.001) optical density, cell density, biomass concentration and total lipid in moderate nitrogen concentration (1N) under 25psu of salinity condition. However, the total protein and carbohydrate were significantly higher (P < 0.001) in the high nitrogen concentration (2N) under 20 psu of salinity. The present study reveals that the combined effects made a huge impact on growth and biochemical variation in the microalgae.
