They brought the student excellence of Toulouse (Haute-Garonne) to the international stage and above all its emblem, the violet. Six students from Paul-Sabatier University and INSA Toulouse won first place in iGem, a prestigious synthetic biology competition against 350 teams from around the world. This is the first time that a French team has won the competition in the flagship under 23 category. Supervised by researchers and doctoral students from the Toulouse Biotechnology Institute, the Center for Integrative Biology in Toulouse and the Plant Science Research Laboratory, they imagined the Elixio project, consisting in reproducing the fragrance of violet using a biotechnological system and therefore sustainable.

"A violet accord is very difficult to obtain naturally, so it is often reproduced using petrochemicals," explains Camille Pin, a master's student in biotechnology at Paul-Sabatier University.
We have created a biotechnological system with two microorganisms: a yeast that we have worked to produce the main scent of violets and a cyanobacterium capable of photosynthesis by living thanks to light and CO2.
We have worked all summer to obtain this organic, sustainable and non-polluting system and to be ready by the end of September â.
The biotechnological process developed by Toulouse students is already of interest to the Robertet company, in Grasse, for a more ecological production of the violet fragrance.
