利用均匀设计法设计得到的12种培养基及对照Zarrouk培养基对钝顶螺旋藻（SpirulinaPlatensis）S。品系进行培养，进行了不同培养基对螺旋藻生长速度和氨基酸含量、β-胡萝卜素及叶绿素α含量的研究，优选出能使藻体生长速度加快、藻粉质量提高，并使养殖成本降低的3种不同配方的培养基。与Zarrouk培养基相比，3号、6号和7号培养基可使藻体生长速度加快，且藻粉产量和质量均有提高，3种培养基均可使养殖成本大幅度降低。其中3号培养基成本最为低廉,β-胡萝卜素含量最高（达154.21mg／100g）；6号和7号培养基相差不大，其藻粉中叶绿素α含量、氨基酸含量等指标均有大幅度提高。
Twelve kinds of medium designed by uniform design and control Zarrouk medium were used to culture Spirulina Platelate S. Strains were cultured, the different medium of Spirulina growth rate and amino acid content, β-carotene and chlorophyll a content of the study, preferably to enable the growth of algae to speed up the quality of algal flour, and reduce the cost of farming 3 different formulations of medium. Compared with Zarrouk medium, No.3, No.6 and No.7 medium can accelerate the growth of algae, and the yield and quality of algal flour increased. All three kinds of culture medium can greatly reduce the breeding cost. Among them, the cost of medium 3 was the lowest and the content of β-carotene was the highest (154.21mg / 100g). No significant difference was found between medium 6 and 7, and the content of chlorophyll a, improve.
