Shining, Colored LED Lighting on Microalgae for Next-Generation Biofuel

As biofuels continue to present challenges, microalgae are gaining momentum as a biofuel energy crop. In the Journal of Renewable and Sustainable Energy, researchers 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, typically extracted from sea salt fields and found in salt lakes.
