    • Abstract

       

      The effects of metabolic inhibitors, thiourea, sodium bisulphite 2, 4-dinitrophenol, 2, 4-dinitrophenyl hydrazine, actinomycin-D, cycloheximide and 8-azaguanine on the nitrogen fixing heterocystous, heterotrichous stigonematalean blue-green algaWestiellopsis iyengarii were studied. In general three types of responses were discernible: an inhibition of growth in higher concentrations, partial suppression of heterocyst, and total inhibition of sporulation.
