title: Effect of phytohormones on the growth dynamics and macromolecular contents of two extreme halophilic Cyanobacteria (Phormidium sps).
abstract: Two non-heterocystous, filamentous solar saltern extreme halophilic cyanobacteria viz., Phormidium tenue and Phormidium fragile were allowed to grow in different concentrations of phytohormones. Among the phytohormones, Indole-3 acetic acid and Indole-3-butyric acid at 0. l ppm concentration enhanced the growth, pigments and carbohydrate content in P. fragile. The phycobiliprotein production was found higher at 0. l ppm concentration of Indole-3-acetic acid in P. tenue, whereas Indole-3-butyric acid at 50 ppm and 0. 1 ppm concentrations proved to be inhibitory in the protein and carbohydrate contents in P. tenue.
