The growth of a blue green alga, Tolypothrix tenuis was investigated with respect to the effects of various environmental conditions; light intensity, temperature, composition of culture medium. An improved medium for growth experiments and another for economical culture of the alga were devised.
The effects of various light intensities on the nitrogen fixation of the organism were investigated. The use of low light intensities for obtaining a good yield of fixed nitrogen was recommended.
