天蓝色素马雷讷素(marennine)研究现状

马雷讷素(marennine)是一种由牡蛎舟形藻产生的水溶性天蓝色多酚类色素，它能够使牡蛎的腮和唇瓣变绿从而提高其经济价值。对于马雷讷素的研究涉及其理化性质、化学结构、生物学活性、分离纯化及分析测定方法等方面。牡蛎舟形藻是硅藻门中唯一能够产生马雷讷素的海洋硅藻，光照、营养、温度、藻类竞争、藻体与牡蛎之间的相互作用等条件影响马雷讷素的产生和积累。利用各种型式的生物反应器在人工控制条件下培育牡蛎舟形藻获取高产量的马雷讷素也得到了研究和应用。

Research Progress of Azure Pigment Marennine

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.
