Light emitting diodes (LEDs) applied to microalgal production [PDF]
Trends in Biotechnology, 2014 Light-emitting diodes (LEDs) will become one of the world's most important light sources and their integration in microalgal production systems (photobioreactors) needs to be considered. LEDs can improve the quality and quantity of microalgal biomass when applied during specific growth phases.
