Abstract: The present invention provides a method for the simultaneous enhancement in biomass and lipids containing omega-3-fatty acids of Thraustochytrid microalgae in a single step using synergistic effect of chemical mixture in appropriate proportion in production medium. The process discloses enriching the biomass of microalgae with high value lipids by subjecting the microalgal cells in growth medium supplemented with unique combination of chemical modulators and carbon substrates in the presence of nitrogen. The present invention also provides a novel strain Schizochytrium sp. (MTCC 5980) for use in continuous aerobic fermentative lipid production process for enhancing high value lipids like Docosahexaenoic acid (DHA), Docasapentaenoic acid (DPA), Eicosapentaenic acid (EPA) and lipids for biodiesel.

Abstract: The present invention relates to a process for producing enriched algal biomass having high lipid productivity. More particularly, the present invention provides a process for obtaining an enriched biomass with omega-3 fatty acids by using a microalgal strain Schizochytrium MTCC 5980 in a unique media composition and substrate residual band in a steady state continuous fermentation. The process of the present invention results in high biomass and lipid productivity.
