Algal Meadows Purify Water from Dangerous Bacteria

The coastal thickets of algae can significantly reduce the amount of pathogenic bacteria in sea water. This was concluded by experts of the Cornell University (USA).

Algal Meadows Purify Water from Dangerous Bacteria

The number of enterococci in water samples taken in the vicinity of the popular U.S. beaches exceeded the safe level 10 times. This is due to the ingress of sewage into the ocean. At the same time, samples taken in the area of algal meadows, contained three times less harmful bacteria. It is still unknown how plants purify the water: perhaps the germs just stick to the algae. According to another version, organisms that feed by pathogenic bacteria can live in the bush. In any case, the study authors emphasize that the algal meadows ecosystem is of great importance for the planet.
