Présentation

Instead of eliminating biofilms, couldn't we take advantage of them?

I am currently conducting research on the concept of positive biofilms as part of a scientific collaboration between Lallemand Animal Nutrition company and the Micalis Institute.

The objective of this partnership is to develop microbial solutions aimed at modulating the microbial ecology of surfaces by applying beneficial bacterial consortia selected in the laboratory according to specific criteria.

These beneficial bacteria develop on surfaces in the form of a positive biofilm, limiting the colonization of undesirable bacteria, such as pathogens or spoilage microorganisms.

In practice, I study the synergistic interactions between different beneficial bacteria and decipher the mechanisms involved in their antagonistic effects against undesirable bacteria in multi-species biofilm models.

The results obtained directly contribute to understanding the modes of action of positive biofilms and to the development of next-generation products.
