title: [Biological characteristics of the spirulines].
abstract: The biological characteristics of Spirulina are reported in this study. The cellular structure and photosynthetic membrane structure of Spirulina (Cyanoschizophyta) were viewed by electron microscopy after freeze-etching. Special characteristics of the alga, its ecological behavior in natural carbonated water and its energetic behaviou in the laboratory cultures are also reported.
