ResumoThis chapter discusses the growth of phototrophic bacteria and blue–green algae. The considerable amount of physiological and biochemical work employing blue–green algae involves a few species. Anabaena variabilis, Anabaena cylindrica, Anacystis nidulans, Nostoc muscorum, and Tolypothrix tenuis are some whose relatively rapid growth rate and ease of cultivation permit convenient biochemical examination. Macroscopic growth of blue–green colonies may sometimes be seen in streams and ponds as well as on soil surface, old brickwork, and concrete guttering. The chapter describes some general media that are suitable for several species of Myxophyceae. It discusses some of the special media suitable for a particular species, or group of species. The major variable open to studies on blue–green algae nutrition is the supply of nitrogen. Nitrogen may be supplied as nitrate, nitrite, or ammonia and the presence of such ions in the medium prevents nitrogen fixation.
