Suite du projet « Mixotrophia » de Pauline Hégaret
Pauline Hégaret poursuit son projet Mixotrophia avec la précieuse collaboration d’Hélène Hégaret, directrice de recherche CNRS au sein du LEMAR (Laboratoire des sciences de l’environnement marin) à l’Institut Universitaire Européen de la Mer (IUEM). Spécialiste des interactions bivalves/microalgues toxiques, la chercheuse en biologie marine est co-responsable du programme de recherche ANR HABIS qui porte sur la prolifération des microalgues toxiques.
A travers ce projet l’artiste désire interroger les phénomènes de la bioluminescence et la communication inter-espèces.
Aimant les expériences extrêmes, elle prévoit de s’immerger dans une colonne d’eau de mer contenant des microalgues bioluminescentes afin de capturer leurs réactions au contact de son propre corps.
Il s’agit donc ici de préparer le dispositif de la performance à venir. Les deux complices versent les souches de microalgues bioluminescentes (Lingulodinium polyedra), préalablement sélectionnées et cultivées, dans un photobioréacteur annulaire vertical de taille humaine. Ces bioréacteurs sont utilisés au LEMAR pour cultiver les micro-algues en grande quantité.
Hélène Hégaret a préparé deux flacons de culture de microalgues bioluminescentes pour le projet Mixotrophia de Pauline Hégaret. Décembre 2025
