Identification of valuable compounds from the shell of the edible oyster Crassostrea gigas
This thesis program was carried out in a partnership between the oyster farming company Tarbouriech-Médithau, located on the edge of the Thau lagoon (Marseillan), and two institutes of The Balard Chemistry Centre of The University of Montpellier: The Institute of Biomolecules Max Mousseron and The I...
