Paper Abstract

The EChO Exoplanet Atmosphere Characterization mission will have in the midst of its main targets, planets that orbit M stars in their or very close to their habitable zone. In this framework at the Astronomical Observatory of Padova (INAF) we are going to perform experiments that will give us an idea about the possible modification of the atmosphere by photosynthetic biota present on the planet surface. In the framework of the project "Atmosphere In a Test Tube", planetary environmental conditions are being performed. The bacteria that are being studied are Acaryochloris marina, Chroococcidiopsis sp., Cyanidium Caldarium and Halomicronema hongdechloris and tests are being performed with LISA ambient simulator in the laboratory of the Padova Astronomical Observatory.
