Projektbeschreibung
Eine umfassende Modellierung von mikrobiellem Verhalten: Grundlage für eine bessere biologische Sanierung von verschmutzten Aquiferen
Aquifere sind Gesteins- und/oder Sedimentkörper, die Grundwasser speichern. Ein erheblicher Teil der Weltbevölkerung wird dadurch mit Trinkwasser versorgt. Die Grundwasserverschmutzung stellt ein zunehmendes Problem dar, das die Gesundheit von Menschen und Ökosystemen beeinträchtigt und den Zugang zu sauberem Wasser beschränkt. Zersetzungsbakterien können die Grundwasserbelastung in Aquiferen im Zuge einer biologischen Sanierung verringern. Diese Methode ist allerdings nicht optimal, da es noch keine genauen Modelle gibt, die den Stoffwechsel von Mikroorganismen und ihre physikalische Interaktion mit dem porösen Medium berücksichtigen. Das von den Marie-Skłodowska-Curie-Maßnahmen unterstützte Projekt MICROLIFEPAQS wird anhand von modernen, jüngst erhobenen mikrobiologischen Omikdaten die Modellierung des biologischen Schadstoffabbaus verbessern, um fortschrittliche Strategien zur biologischen Sanierung zu fördern.
Ziel
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.
