They think that a few top people are key, don't provide increased funding once these hotshots move in, so that more proposals are chasing the same $. Lots of 🇨🇦 talent unfunded and unseen. 🧪 12712

pbbeauregard.bsky.social @pbbeauregard.bsky.social · 22/07/2025My vintage protocol uses the sodium salt for glutamic acid, and the pH of the MOPS stock solution is adjusted with NaOH. So, the final medium contains a mix of both. We also recently observed that the exclusive presence of K vs Na changed the phenotype of the colony. 030
pbbeauregard.bsky.social @pbbeauregard.bsky.social · 08/04/2025Nous aurons le plaisir d'accueillir Géraldine Laloux (UCLouvain) et Jesse Shapiro (Université McGill), et il y aura de multiples possibilités de présentations et d'affiches.

Le BiSP (bactériologie intégrative, symbiose et pathogénèse) aura lieu le 5 et 6 novembre à l'Université de Sherbrooke - un événement qui sera en "symbiose" avec le MicrHub, rencontre annuelle de tous les microbiologistes de Sherbrooke. À ne pas manquer! 143

pbbeauregard.bsky.social @pbbeauregard.bsky.social · 05/12/2024Interesting! I have never seen that before. No idea what/why it is different!! 010
pbbeauregard.bsky.social @pbbeauregard.bsky.social · 25/11/2024We use Na-glutamate but I am unsure if it makes a difference. This could help : journals.asm.org/doi/10.1128/... My take is that the brown pigment is this spore-associated thing, and it depends on pulcherrimin since pulch is required for correct colony development. Some pulch is likely there too.journals.asm.orgCotA of Bacillus subtilis Is a Copper-Dependent Laccase | Journal of BacteriologyABSTRACT The spore coat protein CotA of Bacillus subtilisdisplays similarities with multicopper oxidases, including manganese oxidases and laccases.

pbbeauregard.bsky.social @pbbeauregard.bsky.social · 22/11/2024Or it could be partially complexed pulcherriminic acid (so a bit of pulcherrimin + free pulcherriminic acid) - pulcherriminic acid is soluble. 010
pbbeauregard.bsky.social @pbbeauregard.bsky.social · 22/11/2024To me, left is typical pulcherrimin, red and insoluble. Right is a "brown pigment associated to spore" (no idea what it is exactly) that we observe sometimes (our colonies on MSgg secrete red pigment). It could be dependent of Fe and pulcherrimin because both are required for B. subtilis biofilm. 210
pbbeauregard.bsky.social @pbbeauregard.bsky.social · 16/11/2024Busy week! Paula did an excellent job presenting her project (in her third langage - french!) to the Centre Sève on thursday, on Bacillus species helping or not N fixation. Then, JS, Sandrine and I talked about our research at La nuit des chercheurs hosted by the Science museum of Sherbrooke. 161

pbbeauregard.bsky.social @pbbeauregard.bsky.social · 11/11/2024In presence of high N, B. subtilis negatively impacts A. vinelandii growth; in low N, A. vinelandii feed N to B. subtilis, which in return strongly stimulates Azoto N-fixing activity. Another great collaboration with my chemist colleague JP Bellenger! 110
