The cell wall of the blue-green alga Spirulina platensis was studied with the electron microscope using ultra-thin sectioning, shadowing, carbon-replication or freeze-etching techniques for specimen preparation. The cell wall could be resolved into four layers, L-I through L-IV. The L-I and L-III layers contain fibrillar material. The septum is a three-layered wall: an L-II layer sandwiched between L-I layers. The shape in vitro of isolated septa might be an artifact due to the preparation technique used. Certain structural properties of the septum seem to allow tangential stretching; they might be reflected in the flexible gliding mobility of Spirulina species. The outer, L-IV layer contains material longitudinally arranged along the trichome axis.
利用超薄切片、投影、碳复型或冷冻蚀刻技术制备标本，通过电子显微镜对蓝藻钝顶螺旋藻的细胞壁进行了研究。细胞壁可分为四层，即L-I至L-IV层。L-I层和L-III层含有纤维状物质。隔膜是三层壁：L-II层夹在L-I层之间。由于所用的制备技术，离体隔膜在体外的形状可能是一种假象。隔膜的某些结构特性似乎允许切向拉伸；它们可能反映在螺旋藻属的灵活滑动运动中。外层L-IV层含有沿藻丝轴纵向排列的物质。
