Marine Food Science and Marine Biotechnology

IFREMER is a French institute that undertakes research and expert assessments to advance knowledge on the oceans and their resources, monitor the marine environment and foster the sustainable development of maritime activities. Through a systemic approach, Ifremer plays a part in marine environmental observation on all scales and in understanding ecosystems, the processes governing them and the services they help provide, in a context of global change. Ifremer designs and deploys infrastructures for marine research and monitoring and tools for observation and experimentation, and manages databases. It operates a significant part of the French oceanographic fleet on behalf of the entire scientific community.

Ifremer contributes to national and European strategies for research and innovation, by producing:
  • Fundamental knowledge;
  • More finalised results to respond to questions raised by society;
  • Results and technologies contributing to the socio-economic development of the maritime world.
To these ends, Ifremer is organized into 4 departments:
  • Biological Resources and Environment (RBE),
  • Physical Resources and Deep-sea Ecosystems (REM),
  • Oceanography and Ecosystems Dynamics (ODE)
  • Marine and Digital Infrastructures (IMN)
A few figures on Ifremer:
  • Annual budget of nearly 200 million euros,
  • Personnel: 1 478,
  • 5 Centres (Atlantic, Brittany, English chanel – North sea, Mediterranean, Pacific) and 20 coastal locations along the entire coastline of metropolitan France and in French overseas territories,
  • 6 Vessels (3 offshore), 1 manned submersible, 2 remotely-operated vehicles for deep sea explorations, 2 autonomous underwater vehicles and a full set of test facilities.
The laboratory of Microbial Ecosystem and Marine Molecules for Biotechnology (EM3B) belongs to the Ifremer’s RBE department. It owns unique collections of deep-sea and seafood bacteria (more than 4 500 marine isolates). It conducts research programmes on the characterisation, exploitation and promotion of marine bacteria and their biomolecules (antimicrobial compounds, exopolysaccharides, enzymes) for application in human food (biopreservation), health and environment. Within the research area "quality and safety of seafood products”, EM3B is expert in:
  • Microbial ecology of seafood products (cultural and acultural technics such as TTGE, T-RFLP, New Generation Sequencing Illumina MiSeq)
  • Identification of spoiling microorganism with sensory analysis profiling
  • Predictive microbiology
  • Impact of process and development of mild technology for mastering quality and safety of fisheries
  • Biopreservation of seafood including selection of bacterial strains with an antagonist activity against pathogens and spoiling microorganisms, identification, bioanalysis of genome, production in fermenters, safety assessment, application in seafood, mechanisms of bacterial interaction etc.
Within the research area "exopolysaccharide” EM3B is an expert in:
  • Selecting strains for their "GlycoAminoGlycane mimetic” EPS production
  • Extraction, purification, characterisation
  • Chemical modification as depolymerisation and functionalisation (sulphatation)
  • Enzymatic modification, researching bacterial depolymerases and sulfatotransferases
  • Microencapsulation with EPS
