Marine blue-green algae, Lyngbya Lagerheimii, Microcoleus chthonoplastes, Plectonema terebrans, Agmenellum quadruplicatum, and freshwater blue-green algae, Anacystis nidulans, Anabaena variabilis, Nostoc muscorura, and Oscillatoria sp. treated with lysozyme (muramidase) formed spheroplasts but not protoplasts. The time needed for spheroplast induction varied with the species. Approximate internal osmotic pressures of the blue-green algae were determined. Marine algae generally had a higher osmotic pressure than freshwater algae.
海洋蓝藻，如林氏鞘丝藻、厚壁微鞘藻、穿孔织线藻、四叠片藻，以及淡水蓝藻，如巢状鱼腥藻、多变鱼腥藻、藓生念珠藻和颤藻，经溶菌酶（胞壁质酶）处理后形成原生质球而非原生质体。诱导形成原生质球所需的时间因物种而异。测定了蓝藻的近似内部渗透压。海洋藻类的渗透压通常高于淡水藻类。
