MEB - Topic 5

Biotechnology and Instrumentation


Moderator : Yannick Combet-Blanc


This research axis aims to develop biotechnological processes involving marine microorganisms dedicated to both the production of green energy and highly valuable molecules and bioremediation of environments contaminated by metals. This last part takes place in interaction with topic 4.

This part of the team's research is carried out in partnership with laboratories in southern countries using the scientific cooperation tools of the IRD (expatriation of researchers, MLD, JEAI, International Mixed Laboratory).


Examples of studies



Implementation of an hydrogen production bioprocess from fermentable substrates using microorganisms from hot and marine hot spring ecosystems allowing the use of seawater as culture medium.

Methane production

Example of reconstruction of genomes and metabolic pathways from metaOmic data in anaerobic digesters (Kouzouma et al, 2017)

Study of the robustness of a methane production process under inhibiting conditions using metatranscriptomics.



Fluorescent whole cell molecular probes are developed to understand marine microbial interactions. They are labelling rRNA and mRNA to quantify target microorganisms while expressing specific genes.

TSA-FISH (Tyramide Signal Amplification-Fluorescent In Situ Hybridization) skills are regularly improved and updated (Zeller et al. 2016, Riou et al. 2017, Brient et al. 2017; FISHBOX FUI project)
