    • Offer for a Thesis AllowanceSubject: Characterization of biogas and biomethane: analysis and speciation of trace elements

      The research works that will be carried out within this doctoral thesis is part of the context of energy conversion. They will be conducted in close collaboration with TEREGA (64000- Pau), a major company in the energy sector. The main scientific objective is to expand current knowledge of biofuels and focuses on the chemical characterization (identification, quantification, speciation, isotopic
      signature) of volatile trace compounds present in biogas and biomethane.

    • Offer for a Thesis AllowanceSubject: Influence of the environmental conditions on the methylation rates and source of Hg species in microorganisms

      Mercury (Hg) is a persistent pollutant in the environment, highly volatile and able to be converted into highly toxic methylmercury (MeHg). MeHg is a serious threat as it is a neurotoxic compound, which is bioaccumulated and bioamplified in food webs. Microorganisms play a central role in MeHg conversion, either directly by controlling Hg methylation and MeHg degradation. Although hgcA and hgcA genes have been identified as necessary for Hg methylation, the methylation process cannot be fully explained. Environmental parameters, particularly the sulfur containing ligands, have been shown to play a role in the Hg uptake and methylation process. However, to date, little is known about the cellular and environmental mechanisms favouring MeHg production, and Hg methylation processes are far from being deciphered. In this work, the PhD student will focus on the environmental parameters (thiol containing ligands, Se, Cl…) involved in Hg uptake, methylation and demethylation.
