The mesosome-like structures of blue-green algae were studied by freeze-etching without preliminary fixation and, in parallel, by a technique of ultrathin sections. These structures were found mainly in Synechococcus elongatus and Synechocystis aquatilis, less often, in Anacystis nidulans and Anabaena variabilis, and were not detected in Plectonema boryanum. The following types of membrane structures were encountered: (1) formation consisting of three- and five-layered membranes and resembling the lamellar mesosomes of bacteria; (2) complex structures consisting of five-layered membranes and separated from the cytoplasm by an electron-dense substance not found in bacteria; (3) myelin-like structures; (4) formations intermediate between the mesosome-like and myelin-like structures. These structures were not found to be strictly confined to the growth phase of a culture. Possible functions of the mesosome-like and myelin-like structures are discussed ct. those of bacteria.
通过冷冻蚀刻（不进行预先固定）并同时采用超薄切片技术，对蓝藻中类间体结构进行了研究。这些结构主要存在于细长聚球藻和水生集胞藻中，在巢状鱼腥藻和多变鱼腥藻中较少见，而在博氏织线藻中未检测到。观察到以下几种膜结构类型：（1）由三层和五层膜组成、类似于细菌层状间体的结构；（2）由五层膜组成、被细菌中未发现的电子致密物质与细胞质分隔开的复杂结构；（3）髓鞘样结构；（4）介于类间体结构和髓鞘样结构之间的结构。未发现这些结构严格局限于培养物的生长阶段。文中讨论了类间体结构和髓鞘样结构可能的功能，并与细菌的相应结构进行了对比。
