Some natural environments on Earth are characterised by high levels of radiation, including naturally radioelement enriched mineral springs in the French Massif Central. Therefore, naturally radioactive mineral springs are interesting ecosystems for

Recherche et caractérisation de microorganismes dans les compartiments géologiques profonds

Autor: Barsotti, Vanessa

Over the past 50 years, the scientific community has shown a growing interest for deep geological compartments. However, these ecosystems remain largely unknown due to their inaccessibility. The aim of the present thesis was double; the first aim was
