Synergistic effects of pulse light emitting diode on growth rate, lipid content & its carbon chain of Nannochloropsis sp. In fatty acid methyl ester production

Third generation biofuels which is biodiesel from microalgae has its share of problems such as high cultivation costs, expensive dewatering and drying process, lipid extraction and transesterification. Nannochloropsis sp. was cultivated indoor using pulse light emitting diodes LED, blue LED and red...
