The MICROBIO-E project, funded by the AMIDEX foundation, offers two years of post-doctoral position to develop heat and mass transfer measurements in porous media colonised by biofilms under both steady state and transient conditions. This position is available immediately in Aix-Marseille University.
Hydrogen Dark Fermentation in a porous media is now admitted as a promising process for hydrogen production. Even if the H2 to substrate ratio is quite low due to metabolism limitation, the simplicity of the flow induces little energy consumption. Understanding heat and mass transfer in the neighbourhood of the biofilm with hydrogen generation at the interface is of preliminary importance to prepare the scaling-up. The role of the bubble generation and the hydrogen expulsion and its consequence on the transfers are then in the heart of this study. Moreover, transient conditions are some of the proposed strategies to control this conversion. The biofilm’s parameters affecting the transfers such as thickness, activities, surface properties etc. of the biofilm will have to be included in the study. In practice, transfers will be studied in a full bio-reactor operated in continuous on a long time evolution in order to avoid inhibitors effects. Experiments with well-controlled conditions will therefore be performed to help the understanding of parameters on the overall biofilms efficiency.
The researcher will benefit of the knowledge and support of two communities, microbiologist and chemical engineering. He will have to run the reactor in controlled conditions for long period and he will be responsible of the choice and the installation of probes and measurement devices in the reactor. In a second time, the researcher will have to define proper correlation for heat and mass transfer that could be useful to prepare scaling-up of such processes.
Laboratory Mechanics, Modeling and Clean Process (http://m2p2.fr) involved some 100 members. Global research center studies many fundamental drawbacks linked to processes, as well as more industrial points with financial supports from different national and international societies. For many projects, M2P2 laboratory combines experimental approaches: labscale devices up to large pilots on site; modeling, from the local point of view to numerical process simulations. The part of the researchers involved in the project works in the chemical engineering field, more specifically on processes for wastewater treatment by biological treatment.
Laboratory of Bioenergetic and Protein engineering (BIP, http://bip.cnrs-mrs.fr). The research Unit “Bioenergetics and Protein Engineering” is currently composed of 50 members (25 researchers, 12 technical support staff, 7 PhD, 3Postdoc). BIP is at the head of the French BioH2 research group and most of the researchers are involved in steering and evaluation comities of research at the national or international level. Our research strategy combine a wide variety of approaches based on biochemistry, molecular biology, proteomics, magnetic and optical spectroscopy, electrochemistry, enzymology and reaction kinetics, functional modelling.
A completed PhD in chemical engineering with strong metrology skills will be appreciated at the start of the postdoctoral appointment. Good knowledge of oral and written English is required.
