Impact of light quality on biomass production and fatty acid composition in Chlorella vulgaris

Last changed: 14 August 2014

Cultivation of microalgae is a globally emerging industry with vast potential. Applications can be found within food, feed, life sciences and renewable fuels. Considering production of polyunsaturated fatty acids, microalgae have a potential to increase the sustainability. An important factor affecting the composition of lipids in the microalgae is the environmental conditions during growth. The present application focuses on impact on fatty acid production of different light quality, monochromatic light provided with LED equipment. Using LEDs for algae cultivation represents both an opportunity to regulate the growth and metabolite production and decrease in energy consumption during cultivation. This project is of importance to develop the use of microalgae for sustainable production of metabolites such as polyunsaturated fatty acids. The project is funded by Åforsk.
