Field of Interest: Natural Products From Algae, Light Harvesting Proteins, Photochromes and Photosynthesis sensing
Background: Phycocyanobilin  is a linear pyrrole blue phycobilin based natural product found in Spirulina species that acts a photosensor in light harvesting arrays in photosynthesis 1,2   It also is a potent peroxyl radical scavenger and is indicative of specific algae species as fluorometric markers of different photosynthetic antenna pigments .3,4
