Title: Effect of Different P Mass Concentrations on Growth and P-in-cell of Microcystis aeruginosa
Abstract: The effects of different phosphorus concentrations of water system on DTP, P-in-cell content of tissues (QP) and cell multiplication of Microcystis aeruginosa were studied in laboratory experiments. In the simulative culture medium of Taihu Lake water, the growth of algae was limited by P-limited (ρ(TP)≤0.045 mg/L) firstly and then by light-limited (ρ(TP)≥0.445 mg/L) with the increase of P concentration in the medium, and (ρ(TP)=)0.445 mg/L was the best growth concentration. At the same time, the P-in-cell of Microcystis (QP) and DTP in the medium also changed. When ρ(TP)0.445 mg/L, the cell multiplication of Microcystis aeruginosa was accelerated by the increase of P-in-cell content of Microcystis aeruginosa. Moreover, when ρ(TP)0.445 mg/L, the cell multiplication of Microcystis aeruginosa was restrained by the content of P in the water system.
