The study explored how different LED light qualities and intensities affected the production of fatty acid methyl esters (FAMEs) from Nannochloropsis sp. over a 14-day period.
The optimal light conditions for biomass growth and lipid content were identified as red LED at 150 μmol, blue LED at 100 μmol, and mixed red-blue LED at 200 μmol.
Results indicated that LED light quality and intensity significantly impacted FAME composition, with blue LEDs producing FAMEs with high unsaturation and low cetane number, while red LEDs produced the opposite, and the mixed combination yielded favorable ignition and stability properties.
