Abstract: Marennine, a kind of water-soluble azure polyphenol pigment produced by marine diatom—Haslea ostrearia, can enhance the green color of oysters   gills and labial palps and increase the economic value. Studies on marennine involved in its physicochemical properties, chemical structure, biological activity, purification and determination methods are discussed in this paper. Haslea ostrearia is the only marennine-producing marine diatom from Bacillariophyta. Moreover, the productivity and accumulation of marennine are affected by irradiation, nutrients, temperature, algal competition, interaction between algae and oysters. Bioreactors are also used to cultivate Haslea ostrearia under the controlled conditions for achieving high yield of marennine.

Key words: marennine, water-soluble azure pigment, Haslea ostrearia (Gaillon/Bory) Simonsen
