Researchers, doctoral students, research staff and industry representatives gathered on 22 and 23 September 2025 in the magnificent Manège de Brack in Dole. The HARMI Symposium (Harnessing Microbiomes for Sustainable Development)  provided an opportunity to present the latest research, discuss issues and exchange innovative ideas on topics such as microbial ecology and community management, microbiota-host interactions and biotechnologies.

Doctoral and post-doctoral students from the PAM lab were in the spotlight for this second symposium, with Chloé Abry, Simon Manceau and Truc Phung giving brilliant presentations on their research work. Chloé Abry presented her findings on the use of seaweed extract to combat Brettanomyces spoilage yeast. Simon Manceau presented his work on the use of vesicles to improve the biofilm formation of Lacticaseibacillus casei. Truc Phung presented his research on evaluating the adhesion potential of probiotic bacteria to the intestine using physicochemical approaches.

These young researchers were also rewarded for their participation in the photo competition entitled ‘Microorganisms in all their forms’ with the jury prize for educational photography for Chloé and the prize for humorous photography for Simon.

This symposium also gave senior researchers from the UMR an opportunity to highlight their work. Louise Basmaciyan presented her research on the impact of chemical inputs on the gut microbiota, while Pierre Lapaquette presented his work on the study of autophagy during the invasion of intestinal epithelial cells by Candida albicans. Numerous projects carried out within the PAM lab were also highlighted during the poster sessions.

This second symposium was rich in scientific sharing and exchange in a welcoming and friendly setting, promising to stimulate research in Bourgogne Franche Comté.
