Abstract

Four filamentous cyanobacteria strains Oscillatoria cortiana,Oscillatoria acuminate,Oscillatoria anguina and Leptolyngbya foveolara in freshwater were studied under laboratory conditions.Experiments were performed to determine their growth in the presence of a wide range of concentrations of nitrogen and phosphorus.The results showed that O.cortiana and L.foveolara had a greater adaptability to survive in high concentration of nitrogen or phosphorus than the others,and they grew well with a concentration of NO₃^--N from 0.016 to 2.0 mg·mL^-1 or phosphorus ranging from 1.36 to 13.6 μg·mL^-1.Growth of four strains was inhibited under the condition in which only NH₄⁺-N was supplied.

Key words： filamentous cyanobacteria nitrogen phosphorus growth
