The Groupe Français de Bioénergétique (GFB) is a non-profitassociation under the 1901 law whose objective is to developscientific research in Bioenergetics and to bring together all thelaboratories working in this field.

Bioenergetics studies the mechanisms of energyconversion by living organisms whether bacteria, unicellulareukaryotes, fungi, plants, animals and humans. This energy can belight, electrical, chemical, osmotic, mechanical or thermal.

What is GFB ?

What is Bioenergetics ?

The conceptual foundationsof Bioenergetics were builtaround the chemiosmotictheory, formulated in 1961by Peter Mitchell.

Bioenergetics lies at the frontiers of biology, physics andchemistry.

It involves various techniques and disciplines as varied andcomplementary as genetics, molecular biology, genomics, proteinbiochemistry, crystallography, modelling, cell cultures, highresolution microscopy, fluorimetry, high resolution spectroscopy,analytical biochemistry, proteomics, metabolomics, high resolutionspectrometry, high resolution oxygraphy, etc.

Equipped with powerful tools, bioenergeticianstrack mechanisms of energy conservationfrom the single molecule level to thewhole organism.

Bioenergetics is a fundamental discipline whose primaryambition is to increase knowledge about the mechanisms of energyconversion by living organisms. The societal issues of thisknowledge are enormous, particularly in the fields of:

New energies :

Health and well-being :

Bioenergetics makes a major contribution to the study ofpathologies related to mitochondrial dysfunction and to thestudy of drug resistance in cancer. Bioenergetics participates inthe study of processes or phenomena such as cell death andoxidative stress at the heart of the mechanisms of development,aging and degeneration. Bioenergetics also brings a newperspective to the study of pathologies related to an imbalanceof the microbiota in the digestive or respiratory tracts.

A detailed understanding of the mechanisms ofphotosynthesis and of energy conversion carried out bymicroorganisms is essential for the development and evaluation ofnew environmentally friendly energy production methods.

What is the purpose of Bioenergetics ?

The decoding of the functioning of proteins involved inbioenergetics has many applications in industry such as themanufacture of biocells and biocatalysts.

GFB is open to researchers, professors, engineers, post-doctoral researchers and PhD students from all researchorganizations (CNRS, INSERM, CEA, INRA, Universities,Hospitals…) as well as private sector research actors in the fieldof Bioenergetics.

Organization of a biennial national congress

To maintain a dynamic of collaboration between thedifferent laboratories, for more than 40 years, the main activityof GFB is the organization of a biennial congress. With some 100participants, this congress offers an irreplaceable framework fortaking stock of research in Bioenergetics at the national level andfor in-depth discussions covering the entire discipline.

Promoting young researchers

Young researchers represent 40% of the congressparticipants. 50% of oral presentations are given by PhDstudents who thus have the opportunity to present their work infront of their peers for the first time. This represents the firststage to later participate to International conferences such as theEBEC (European Bioenergetics Conference) or prestigiousconferences such as Gordon Conferences "Bioenergetics" or"Mitochondria and Chloroplasts".

A national congress, open to international participantsGFB conferences obviously welcome foreign researchers of all

nationalities. Most of them are PhD students or post-doctoralfellows working in France, but a few come from foreignlaboratories, particularly European ones. Since 2011, severalinternationally renowned foreign researchers have been invited toplenary conferences.

The distribution ofbioenergeticians is quiteuneven across the country,but all regions where thisdiscipline is representedsend participants to GFBcongresses.

Scientists from allmajor biological researchorganizations as well asuniversities and collegesattend GFB congresses.

A source of fellowships for studentsEvery two years, a dozen of fellowships covering the registration and lodging

fees are granted to PhD students to attend the GFB conference. On the basis of thepresentation of their results at the GFB conference, students can earn fellowshipsto attend the European Bioenergetic Conference.

A network to share informationGFB creates a network to share scientific, technical and practical information.

New scientific collaboration are initiated at each conference. PhD or post-docpositions are regularly announced on the GFB website and through the mailing list.

GFB is represented in the international organizingcommittee of EBEC (European Bioenergetics Conference)

GFB is primarly financed through the payment of membershipsand conference registrations.

GFB receives financial support of private and public sponsors forthe organization of its biennial conference.

Private companies support financially GFB conferences. Inreturn, GFB allows oral presentation of sponsors, distribution ofadvertizing material and/or venue at commercial booth during theconference.

Private, public and associative sponsors are indispensable tomaintain affordable conference registration fees, to invitereknown international speakers and to offer fellowships toPhD students for participation to GFB and EBEC conferences.

«Accessibles à l’observation par de multiples approches spectroscopiques, les processusbioénergétiques ont suscité l’intérêt d’une communauté très variée et ceci bien avant que lescomplexes protéiques, sièges de la transduction d’énergie, ne soient accessibles aux étudesbiochimiques, moléculaires ou encore structurales. Aujourd’hui, la plupart des composantsessentiels des chaînes de transfert d’électron respiratoire ou photosynthétique sont connus àl’échelle atomique et la description des chemins réactionnels qu’ils empruntent a atteint unniveau de précision mécanistique peu commun en biologie. Cette connaissance approfondiepermet à la communauté des bioénergéticiens d’étendre son champ d’investigation pours’intéresser aux régulations physiologiques des processus métaboliques ainsi qu’à la diversité desstratégies mises en œuvre pour décliner les grands principes de la bioénergétique end’innombrables variations et les adapter ainsi à la diversité environnementale ».

« Appréhender les mécanismes de transport mitochondriaux à l’échelle moléculaire apporte unevision unique des protéines impliquées dans l’échange ADP/ATP lié à la production de l’ATP. Lesanalyses des relations entre structure, fonction et dynamique couplant cristallographie,dynamique moléculaire et études fonctionnelles sur les transporteurs isolés sont essentielles,mais n’apportent qu’une réponse partielle. Les congrès rassemblant la communauté du GFB sontdes moments privilégiés d’échanges entre chercheurs couvrant plusieurs disciplines permettantainsi la confrontation entre informations moléculaires et données à l’échelle cellulaire ou del’organisme entier. Une telle intégration est indispensable à la compréhension des processusbioénergétiques cellulaires ».

« La bioénergétique correspond à une dimension essentielle de la biologie : aucun mécanisme,aucune interaction ou voie métabolique ou processus biologique n'échappe aux contraintes ouordres imposés par l'énergétique. Comparée à la lecture de cartes métaboliques ou la lecture desuccessions de réactions, la dimension bioénergétique donne ordre, vitesse et taille auxévénements biologiques au sein d'un système. La bioénergétique est aussi un véritable langageentre biologistes, que l'on traite de cellules de méristème, de levures, neurones ou micro-organismes, nous nous comprenons tous et ainsi, grâce au GFB, nous amélioronsconsidérablement notre compréhension du vivant et sommes meilleurs chercheurs et meilleursenseignants ».

«Mon activité scientifique est consacrée à l’étude du métabolisme de la cellule végétale. Unegrande rigueur dans la préparation et la caractérisation des mitochondries et des chloroplastesdes plantes supérieures m’a conduit à mettre en évidence les spécificités fonctionnelles desmitochondries des plantes ainsi que celles associées à l’enveloppe des chloroplastes. En utilisantles outils performants empruntés à la physiologie, à la biochimie, à la biologie moléculaire etenfin à la physique (RMN, Spectrométrie de masse) mes travaux ont conduit à une visionnouvelle de la dynamique et de la très grande flexibilité du métabolisme de la cellule végétale ».
