Multiomic approach to characterize the link between the structural biodiversity and the microbial activity along the natural evolution of periphytic biofilm

MICROBIOMIQ aims to better understand the link between the microbial activity (i.e. metabolome), the structural biodiversity (diversity of species and genes) and the sensitivity to the chemical stress associated to natural fluctuation in the species composition and the functioning of periphytic communities due to changing environmental conditions along the year. Thus, through the combination of metagenomic and meta-metabolomic on periphyton, this project will focus on the modulation of the photosynthetic function that is strongly involved in primary production and overall biogeochemical cycles. The outcomes of the project will allow to better understand the adaptive mechanisms (e.g. phenotypic plasticity) in the sensitivity of ecosystem functions (i.e. photosynthesis) to the chemical stress and their time sequence. The collected data would be further used to support the development of management tools in a water quality biomonitoring purpose.
