We are also currently writing and submitting various articles, and it is going well up to now. The article part of Jean-Sébastien master’s thesis, in which he examined in detail the parameter that favors the conjugative and integrative element ICEBs1 propagation in biofilm, was published in Journal of bacteriology. In this paper, we observed that the conjugative transfer in biofilm occurs in hot spots that are preferentially located at the air biofilm interface (see the beautiful picture on the right!). Jean-Sébastien also demonstrated that transconjugant cells are responsible for more than 99% of transfers in biofilm, and thus play a major role in the high conjugation levels observed. The positive comments received during peer review lead our paper to be chosen as Editor’s pick, and to be the subject of a commentary written by Pre. Sophie Payot. Congratulations to Jean-Sébastien, and to Sandrine et Gabriel, for this excellent work!
The last months were very busy in the lab, with the arrival of several new persons. First, we were very happy to welcome back Paula, who was in the lab in 2018 with an ELAP fellowship. After finishing her master’s degree in Colombia, Paula decided to do a PhD with us. She will work in close collaboration with Andrea, who did an internship this winter and came back this fall to start her PhD. This summer, it is with pleasure that we hosted the first “T0” intern of the laboratory, Emile, who worked with David on Abeta production by neural cells. And finally, Lucille came from France for a 6-month internship, during which she will do experiments on Bacillus evolution on plant roots with Maude.
