The project
Dental caries is one of the most prevalent global chronic diseases. It is intimately linked to oral biofilms formed on the tooth surface (dental plaque), in which Streptococcus mutans plays a key role. Recently, mutanofactins were identified as small-molecule secondary metabolites of S. mutans, promoting cell adhesion and biofilm formation. However, the mechanisms by which mutanofactins promote biofilm formation are unknown.
In a research consortium including groups from BOKU Vienna and ETH Zürich, we will use a unique combination of synthetic, microbiological, and physicochemical approaches to establish cariogenic model biofilms and characterize bacterial cell surface properties and biofilm matrix interactions, possibly affected by mutanofactins. The project outcomes will inform innovative, effective anti-cariogenic strategies urgently needed for human health and reduce the global economic burden of tooth decay.
Our goal
In one of three interlinked Post Doc and Ph.D. projects, we will focus on understanding the molecular basis of action of mutanofactins, as single compounds and their mixtures to assess potential synergistic effects. This includes analysis of effects on bacterial growth, stress tolerance and biofilm formation of consortia including competing oral streptococci and cohabiting cariogenic biofilm species.
We will create a hierarchical model interlinking the interaction of mutanofactins to structural and mechanical properties of biofilms to understand the presumably novel mechanisms by which these secondary metabolites control cariogenic biofilm formation.
Your job
**Benefits**:
What we offer
The project is interdisciplinary, with strong collaborations across scientific disciplines.
The project’s coordinator is Prof. Christina Schäffer (BOKU Vienna); other project partners are Prof. Erik Reimhult (BOKU Vienna) and Prof. Erick Carreira (ETH Zürich). You will work at the Institute of Biologically Inspired Materials (BIMat), University of Natural Resources and Life Sciences (BOKU), Vienna, supervised by Prof. Christina Schäffer, in an interdisciplinary group spanning microbiology, physics, and chemistry.
BOKU offers the complete infrastructure for microbiology work (including BSL-2 laboratories), genetics and biochemistry laboratories, including analytics for extracellular molecules such as Dionex, HPLC, FPLC, GPC/SEC as well as RT-qPCR; and biomolecular interactions and microscopy laboratories, including FTIR, ITC, DSC, SPR, QCM-D, and BLI, TEM, cryo-SEM, CLSM with STED for imaging bacteria and biofilm structure and interactions; license to work with GMOS; access to the core facilities “Biomolecular & Cellular Analysis”, including SPR, BLI, DSC and ITC and “Mass Spectrometry” at BOKU.
