Phycobiliproteins were separated by using hydroxyapatite column chromatography from phycobilisomes of Synechococcus 6301. Thick blue fractions have been identified by spectroscopically as phycocyanin (PC) and light blue fraction has been identified as allophycocyanin (APC). Between PC and APC, PC seems to be more sensitive to action of Mercury (Hg+2) or Copper (Cu+2) as evidenced from the spectral alterations of PC in the above organism.
