At the crossroads of environmental protection and public health issues, we are developing a three-fold scientific, industrial and commercial expertise. The company is developing around multiple applications using the amoeba Willaertia magna C2c Maky in the prevention of microbiological risk for water treatment, human wounds and plant protection.



Plants protection

We found that mechanically lysed amoeba Willaertia magna C2c Maky exhibited strong fungicidal properties.

First on oomycetes (microorganisms close to fungi and responsible for mildews) then on phytopathogenic fungi such as rusts, powdery mildew, etc.

This has been demonstrated in laboratory tests and then, since 2019, has been verified in field trials.

The only biological biocide that can be used in air cooling towers, with no hazard class for human health and the environment.

Water treatment

Our disruptive biocide helps control the level of Legionella, both those present in the water and those colonizing the biofilm.

The effectiveness of the biocide is due to the natural properties of the amoeba Willaertia magna C2c Maky, which predates pathogenic bacteria and other free-standing amoebae.

For the first time in 50 years of industrial water treatment, Amoéba is giving industry the opportunity to choose a responsible alternative.
