    • Abstract


      Detailed study was made of the effect of (i) various inorganic and organic sources (potassium nitrate, ammonium sulphate, ammonium nitrate, asparagine, urea) and (ii) various levels of nitrogen (280, 700, 1,400 and 2,100 mg. N per litre) on growth and metabolism ofD. sorokiniana. Observations on mat weight, spore numbers, shift in pH of the medium, nitrogen accumulated in the mat, residual nitrogen (total, nitrate and ammoniacal nitrogen) and residual sugar in the medium were made after incubation for varying periods. The results are presented in detail and discussed.
