Figure 5. (A) The cyanobacterium Lyngbya sp. A09DM, grown in liquid media and fully acclimated to white (left) and red light (right). The color of crude extract (shown along with cell mass) indicated the alteration in phycobilisome pigment composition in a complement manner to absorb the available light. (B) The absorbance spectra of crude extract of white and red light acclimated Lyngbya sp. A09DM. Red light exposure switches the dominance of phycoerythrin by phycocyanin in phycobilisomes.
