摘要
为筛选出能应用于大规模盐藻生产的最适培养基,选择7种常用的培养基来培养盐藻,分析其生物产量和色素含量。试验结果表明,改良Johnson培养基和改良Pick培养基能较好的促进盐藻的生长和色素累积,但生长和色素累积的最适培养基不一致,改良Pick培养基培养的盐藻生物产量最高,改良Johnson培养基培养的盐藻色素含量最高。由投入产出比可知,改良Pick培养基最适合于高生物产量和高色素产量兼顾的盐藻大规模生产,而改良Johnson培养基最适合于高色素产量的盐藻大规模生产。
The biomass and photosynthetic pigment contents were detected in green alga Dunaliella salina cultured in seven kinds of culture media to screen out the optimum liquid medium applied in the large-scale production of the green alga .The results showed that the best growth and the maximal accumulation of pigments were observed in the green alga cultured in the media of Pick （1994） ,and modified Johnson and modified Pick （2006） ,with different optimal conditions for growth and photosynthetic pigments accumula-tion .The maximal biomass was found in the green alga cultivated in modified Pick culture medium （2006） and the maximal contents of photosynthetic pigments in modified Johnson culture medium .According to input-output ratio ,it was found that modified Pick culture medium （2006） was best for the large-scale pro-duction of green alga D .salina because of higher biomass yield and pigment content ;while modified John-son culture medium was better for the large-scale pigment content production .
