Algae Carbon Flow Controlled by Changing Light Colors

Facebook Twitter LinkedIn Email
Blue and red light-sensing photoreceptors can be used to control the carbon flow in diatoms, a major group of algae that generates about one-fourth of the Earth’s oxygen and perform around a quarter of global CO2 assimilation. Researchers from Leipzig University and the Helmholtz Center for Environmental Research made the findings, which they said show that cultures pre-acclimated to blue light and red light exhibited similar growth performance, photosynthesis rates and metabolite profiles.
