Microbials as selective Targeted Scaling Precipitation Treatments agents for combined scaling prevention and resource recovery in a geothermal context

This PhD project aims to assess the feasibility of developing microbial-based Targeted Scaling Precipitation Treatments (TSPT) that selectively promote the formation of desired mineral precipitates while preventing problematic scaling in geothermal installations. The project seeks to identify and characterise reservoir-derived microbial strains or consortia capable of modifying mineral nucleation pathways through the production of extracellular polymeric substances (EPS), metabolic byproducts, or surface-mediated precipitation mechanisms.

A central objective is to elucidate microbially induced mineralisation processes relevant both for scaling control and for the selective recovery of strategic metals such as Li, Co, and rare earth elements (REEs). The project further aims to integrate microbial kinetics into predictive biogeochemical models to optimise scaling management strategies under geothermal operating conditions.

The laboratory of microbiology of the University of Neuchâtel is home to a team of scientists and technical staff united by their passion for understanding the processes that underlie the diversity and functioning of microbial ecosystems.
Their combined expertise enables the laboratory to work on a wide range of topics, from basic science to applied research and environmental monitoring. To achieve this, we combine cutting-edge tools such as 3D printing and -omics approaches with traditional laboratory experiments.

The ideal candidate holds a Master’s degree in a relevant discipline and exhibits a strong drive for interdisciplinary research. You possess a robust background in environmental microbiology or biotechnology, specifically regarding microbial-induced mineralization and EPS production. Proficiency in wet lab techniques—including cultivation and growth monitoring—is essential, alongside a foundational understanding of geochemistry and mineral scaling.

Fluency in English and the ability to analyze complex datasets are mandatory. We highly value experience with mineral characterization (SEM, XRD), crystallization pathways, or geochemical modeling. The successful applicant will be a self-motivated collaborator, eager to bridge microbiology with industrial process optimization and participate in pilot-scale testing with our industry partners.
