Algicidal Effect of an Algicidal Bacterium and Preliminary Studies on its Algicidal Mechanism

Article Preview

Abstract:

In this study, algicidal effects of an algicidal bacterium, strain TL, on Microcystis aeruginosa were studied. The results demonstrate that the bacteria-algae ratio had a significant impact on algicidal effects. Illumination conditions affected the algicidal effects of TL as well. In illumination and darkness cycling, the optimum algicidal effects were realized. Algicidal mechanism of TL was further studied. TL may kill algae through the secretion of certain extracellular nonprotein substance. This research may provide technical basis for biological algae control of Microcystis aeruginosa.
