Environment of work: The project is being carried out in collaboration between two CNRS laboratories: CEISAM (Chimie Et Interdisciplinarité : Synthèse, Analyse, Modélisation) for the analytical development side, and the GEPEA (Environnement - Agroalimentaire) process engineering laboratory for the development of processes for microalgae cultivation. CEISAM's MIMM team is renowned for its development of liquid-state NMR techniques, applying these tools to the analysis of complex mixtures, and GEPEA's BAM team for its development of breakthrough, high-productivity culture systems.

Description

Context: Oleaginous microalgae are a source of biomass rich in oil (or triacylglycerol, TAG), an energetically dense class of molecules generated by esterification of fatty acids (FAs). FAs are carbon chains of various structures, which can be of interest to different industrial sectors, from very long-chain polyunsaturated GAs for food, health and cosmetics, to monounsaturated/saturated GAs for commodity chemistry and biofuels. Oil from algae is therefore one of the most promising renewable alternatives to fossil hydrocarbons. As part of the B-BEST priority research program and equipment, the diatom Phaeodactylum tricornutum (PT) will be studied, as it is known to produce large quantities of lipids as TAGs droplet form in the extracellular medium.

The CEISAM and GEPEA laboratories involved in the ALGADVANCE project have a 6-year collaboration in which they demonstrated, as part of the AMER-METAL project, that Nuclear Magnetic Resonance (NMR) spectroscopy gives precise access to the identity and quantity of microalgal lipids [1] directly on the whole biomass, thanks to high magnetic field instruments. On the other hand, compact NMR devices [2] were able to monitor the lipid production of microalgae, thanks to signal elimination from the water medium [3] during 15 days of culture by coupling a photobioreactor [4].

Profil

Profile: Candidates must hold an Engineer school training / Master's degree in (Bio)Analytical Chemistry or Physical Chemistry and have a solid theoretical knowledge in NMR. Previous experience in this field (internship) is appreciated but not essential. The engineer / master https://www.st-malo-hotel-cunningham.com/will also need to be open-minded, given the interdisciplinary and collaborative nature of the project, carried out between two laboratories in the Nantes area. This recruitment will offer a unique opportunity to become involved in innovative developments in NMR, at the interface between spectroscopy, analytical chemistry, biology and process engineering.

This recruitment will offer a unique opportunity to a Master / Engineer to be involved in the application of high and low field NMR to a better understanding of the lipidic metabolism of microalgae. The internship will last 6 months from February 2027 with a possible extension of 5 months.
