摘　　要：对钝顶螺旋藻进行研究和应用过程中分离筛选,获得一直线形变异藻株(Sp-L)。长期观察培养发现,分纯得到的直线形藻株能保持稳定遗传。对其形态、生长曲线、产量、上浮性、蛋白质含量以及常见金属元素(Fe、Mn、Cu、Zn、Ca、Mg)含量进行测定,结果表明直线形变异藻株具有藻丝体长、蛋白质和常见金属元素含量与正常螺旋藻接近及易于采收等特点,为研究直线形螺旋藻提供了基础性的理论依据。A line strain of Spirulina sp. with constant genetics was isolated from Spirulina platensis which is generally helical in shape. Some physiological guidelines, including the shape, the content of protein and the common metal elements (Fe, Mn, Cu, Zn, Ca, Mg), and growth, were determined. It was found that the slim line-Spirulina was the same in length, contents of protein and the common metal elements as the helical one.
