Descrizione del progetto
Modellizzazione completa del comportamento dei microbi che supporta il biorisanamento delle falde acquifere inquinate
Le falde acquifere sono corpi rocciosi e/o sedimentari contenenti acque sotterranee, che forniscono acqua potabile a una percentuale significativa della popolazione mondiale. L’inquinamento delle falde è un problema in crescita che incide sulla salute delle persone e degli ecosistemi e riduce l’accesso all’acqua potabile. Per ridurre l’inquinamento delle falde acquifere attraverso il biorisanamento, è possibile utilizzare batteri degradanti. Tuttavia, tale metodo non è ottimale, poiché mancano modelli accurati che prendano in considerazione il metabolismo dei microrganismi e la loro interazione fisica con il mezzo poroso. Con il sostegno del programma di azioni Marie Skłodowska-Curie, il progetto MICROLIFEPAQS migliorerà la modellizzazione della biodegradazione degli agenti inquinanti attraverso la raccolta di nuovi dati omici microbiologici, al fine di contribuire alle strategie di biorisanamento avanzato.
Obiettivo
Groundwater pollution is a significant threat to human health and ecosystems and one of the leading causes of limited access to good-quality water resources worldwide. Biodegradation is an effective means to remove chemicals from the environment, and several remediation techniques benefit from degrading bacteria to eliminate pollution from aquifers. Reactive Transport Models (RTMs) have proved to be valuable tools to support remediation. However, efforts made so far to model biodegradation in polluted aquifers have been incomplete, as they did not thoroughly consider that microorganisms’ behaviour in groundwater depends on their metabolism and physical interaction with the porous medium.
The MICROLIFEPAQS project aims at implementing a novel and interdisciplinary approach for pollutant biodegradation modelling as reliable support for groundwater remediation optimisation. Modern and newly collected microbiological omics data will constrain RTMs of degrading bacteria with information about their metabolism. Moreover, microorganisms will be considered as reactive biocolloids moving in the subsoil. This omics-informed RTM of biocolloids will be tested in a contaminated test site, considering naturally occurring bacteria or injected/stimulated for bioaugmentation/biostimulation.
Working on this project at the Delft University of Technology will enrich my existing expertise with advanced skills in reactive transport modelling and microbiological analysis modelling. Moreover, the secondment at the Technical University of Denmark will provide additional knowledge about innovative contaminated site investigation and advanced (bio)remediation strategies. This transfer of knowledge will foster research and innovation on these topics. As the United Nations and European Union strive to eliminate pollution to reduce the risk for human health and ecosystems and secure safe water resources and sanitation for everyone, this project will also contribute to this global challenge.
