The present invention relates to the control of green macroalgal blooms. More specifically, Ulva algal blooms can be controlled by live active ingredients contained in Mediterranean seawater. The inventors have observed that Mediterranean seawater collected at specific locations (e.g. at 43°14'N and 5°21'E or at 43°09'N and 5°36'E) can contribute to the death of Ulva, Instead of emitting toxic acid vapors such as H 2 S vapor. In conclusion, the data provided by the inventors indicate that the seawater contains live microorganisms that are responsible for the death of Ulva, especially Ulva. More precisely, the experimental data provided by the present inventors indicate that the microorganisms that contribute to the death of Ulva and thus promote the control of Ulva blooms are viruses. |
