| Abstract: | "OBJECTIVE: To explore the effective agent to inhibit the growth of water-bloom algae and establish corresponding forecast model based on the inhibitory effect. METHODS: The inhibitory effect of pyrogallic acid at different concentrations on Microcystis aeruginosa was studied in the indoor control conditions and the mathematical model of algal growth inhibition was established based on the traditional Logistic model. RESULTS: (1) Pyrogallic acid has strong power to inhibit the growth of Microcystis aeruginosa, the EC50 of the fifth day was 0.658 mg/L. (2) The law of algal density changing with time can be effectively analysed and forecasted by this model, and based on this model, the half effective concentration (EC50) and the minimal inhibitory concentration (MIC) at different time point also can be projected. CONCLUSION: This experiment indicated that pyrogallic acid had some potential to be developed into biological algicide agent, and the mathematical model has some reference application value for using allelochemicals to inhibit the growth of water-bloom algae" |
