Chinese researchers find red and blue LEDs can boost microalga growth and yields

March 30, 2021 |

In China, in their paper, published in the Journal of Renewable and Sustainable Energy, Yangzhou University researchers in China show how a combination of monochromatic red and blue LED illumination on one type of microalga can enhance its growth and increase the biosynthesis of critical components, such as lipids, for microalgae feedstock development.

The researchers focused on Dunaliella salina (D. salina), typically extracted from sea salt fields and found in salt lakes. Easily cultivated and known for its bright pink color because of its high levels of carotenoid, D. salina is widely used in foods and cosmetics.
