摘  要：
Bangia fusco-purpurea,an economic macroalgae,was often cultivated in Zhejiang and Fujian coastal areas.Its cultivation in Guangdong coast and photosynthetic characteristics had not been well documented.In this paper it was transplanted from Fujian Province to the sea area of Nan′ao Island in Guangdong Province,and the photosynthetic characteristics and fatty acids compoment were investigated by using photosynthetic gas exchange and gas chromatography.The results showed that Bangia fusco-purpurea grew well in situ with a higher photosynthetic light saturation point of 210 μmol/(m2·s).The lower light compensation point as well as dark respiration rate were also observed.The polyunsaturated fatty acids(PUFAs) accounted for more than half of the total fatty acids.The eicosapentaenoic acid(EPA) content was 41.20% in the total fatty acids,and reached as high as 499.82 mg per 100 g dry weight,which was significantly higher than that of Porphyra haitanensis or Gracilaria lemaneiformis grown in the same sea area.In conclusion,it was practicable that Bangia fusco-purpurea was cultivated in the sea area of Nan′ao Island.The algae could be exploited as a new source of EPA production because of its higher EPA content.
