Atmospheric microorganisms and their potential role in atmospheric chemistry

Séminaire de Romie TIGNAT-PERRIER, jeudi 14 juin 2018 à 14h, salle 105 OSUG-B

Titre : Les microorganismes atmosphériques et leur rôle potentiel dans la chimie atmosphérique

Résumé :
Atmospheric microorganisms are today accepted as important players of the atmospheric environment. Studies have shown their role in clouds formation and in changing the composition of cloud waters. Microorganisms can also generate organic molecules that are susceptible to change the atmospheric chemical composition and influence reaction processes.

The INHALE project (Investigation of tHe Atmosphere as a reaL Ecosystem, ANR) is one of the first global scale projects that try to identify potential interactions between the chemistry of the atmosphere and the airborne microbial communities.
In this project, we have sampled ten different sites situated at different latitudes from the North to the South pole. Microbiological and environmental measures are being conducted in parallel to evaluate the global geographical distribution of airborne microbial communities (concentration and diversity), the environmental factors driving this distribution and the genetic potential of airborne microorganisms in transforming mercury compounds.
