Description du projet
Une approche respectueuse de l’environnement pour éliminer les polluants
Les organismes biologiques, y compris les plus petits, peuvent jouer un rôle important dans la restauration des environnements pollués. Ils sont susceptibles d’éliminer ou neutraliser certains contaminants du sol ou de l’eau dans le cadre d’un processus appelé biorestauration. Le projet Nymphe, financé par l’UE, permettra de franchir une nouvelle étape dans ce domaine. Plus précisément, il s’agira de mettre au point des stratégies de biorestauration/revitalisation reposant sur l’assemblage de systèmes de produits biologiques déjà disponibles ou nouveaux (enzymes, micro-organismes, bivalves et vers de terre, plantes et leurs holobiontes) développés et appliqués sur des matrices provenant de différents sites contaminés de l’UE (eaux souterraines, sédiments, eaux usées, sols industriels et agricoles). Le projet vise à éliminer au moins 90 % des plastiques et des pesticides contenus dans les sols agricoles et des solvants chlorés/hydrocarbures pétroliers totaux présents dans les eaux souterraines et les sédiments des sites industriels.
Objectif
The objective of Nymphe is to develop bioremediation/revitalization strategies based on the assembly of systems of available and new biologics (enzymes, microorganisms, bivalves and earthworms, plants and their holobiont) developed and applied on matrices from different EU contaminated sites: groundwater, sediments (hyporheic zone), wastewater as well as industrial, and agricultural soils. The assembly of systems is guided using predictive microbial interaction models in the microbiome of the actual site matrix to be decontaminated. The best systems of biologics are reintroduced at the contaminated sites (4 plus 1 site for confined tests using genomically edited biologics). Nymphe target at least 90% removal of the pollutants occurring at the sites, e.g. plastics and pesticides in the agricultural soil, and chlorinated solvents/total petroleum hydrocarbon in groundwater and sediments of the industrial site. Besides, biologics and systems benefit from the development of platform technologies to: assemble stable consortia (adhesin+complementary auxotrophies), accelerate the evolution of the microorganisms, increase mobility of degradative plasmids, genomically edit bacteria to produce evolved enzymes, produce enzyme systems with recycling of cofactors, control the spatial distribution of biodegraders (3D-printing), protect them in harsh environments, facilitate redox processes by electromicrobiology, design self-sustaining redox biocatalysts. The bioremediation/revitalization strategies undergo a full assessment: ecological and environmental risk analyses (chemical, ecotoxicological and supportive analyses e.g. function and biodiversity of the microbiomes), technology risk analysis, life cycle assessment, life cycle cost, cost-efficiency analysis, biosafety & regulatory constraints analysis, and societal analysis to be finally benchmarked with current solutions. The ecological status of the bioremediated sites shall be closer to Natura 2000 specifications
