Phosphate Impact and their Kinetics in Blue-Green Alga Synechococcus aeruginosus nageli

Dr. Kusuma Bhagya Lakshmi Jyothi

Abstract :

Phosphorus is one of the major nutrients required in all phases of metabolism particularly in energy generating and transforming reactions during the development and for the normal growth of microorganisms such as algae which are the primary producers in the food web cycle (Kuhl, 1974).Synechococcusaeruginosus collected from thepaddy fields of Andhra Pradesh, India. The effect of phosphate sources i.e. K₂HPO₄and NaH₂PO₄ on growth of the algae and uptake and kinetics of phosphates were also examined for upto 72 hours of life cycle. Uptake of phosphates followed Michaelis–Menton kinetics in Synechococcusaeruginosus. Based on the results di–potassium hydrogen orthophosphate (K₂HPO₄) supplemented algal cultures showed better growth than sodium dihydrogen orthophosphate (NaH₂PO₄) at all concentrations.
