Microalgae have been proposed as a potential source for numerous products, ranging from proteins used in nutrition to mycosporine-like amino acids (MAA) that could be used in sunscreens to absorb ultraviolet (UV) light. However, one of the major constraints to using microalgae-based products is their low production of high-value products like MAA. GeneBEcon, a Horizon Europe-funded project, investigates the potential to increase the production of valuable compounds in microalgae through gene editing in order to enable a more sustainable bioeconomy in Europe.
