Abstract
A species of marine microalgae (Tetraselmis sp. MACC/P66) was found to secrete an unknown red pigment to the culture medium when itself was still keeping healthy.The unknown red pigment was collected and purified from the culture medium by column chromatography using cation-exchange resins. A process for concentrating and isolating the red water soluble pigment from the culture medium of Tetraselmis sp. MACC/P66 was described in the present invention.
