Ever popped a vitamin B12 supplement? 💊 It turns out microbes need their B vitamins too, and they’re not always easily obtained. B vitamins are built, bartered, and burglarized in microbial communities. 🦠 (1/3) #microsky #SynCom

Are you interested in #phages? The Taga Lab is looking to hire a postdoc with expertise in phage biology to work on a project about phage-mediated nutrient sharing. If you're interested, please reach out to Dr. Taga.

Check out our new paper led by Taga lab alum Florian Widner with collaborators Bernhard Kraeutler and @vitaminb12lab.bsky.social and their research teams: pubs.rsc.org/en/content/a... 1/2 #VitaminB12 #MicroSky

Repression of bacterial gene expression by antivitamin B12 binding to a cobalamin riboswitch

The E. coli btuB riboswitch is a cobalamin-sensing RNA element that selectively binds coenzyme B12 (adenosylcobalamin, AdoCbl) to downregulate the expression of the outer membrane B12-transporter BtuB...

As part of the #McClintockLetters Initiative, members of the Taga Lab wrote op-ed's and letters to their local hometown papers to defend federal science funding. Check them out in this thread and join the fight to defend federal science funding (1/4)!

Taga lab (past and present) will be at #ASMMicrobe2025! Swing by our posters to learn more about corrinoid producers in Archaea and more! Poster details are included in this thread. @asm.org #ASMMicrobe #MicroSky #ASMMicrobe25 #Microbe2025

What a great time with Pete Greenberg, @tagalab.bsky.social, @cwhitch.bsky.social, @laahrs.bsky.social, and Jeff Boyd in Dresden + learning about the history of quorum sensing research, the 2Ms, Matt and Marvin, BB medium, and many more stories

Congratulations to our RaMP scholar, Farrah, for a great talk at the Bay Area RaMP in Microbiome Sciences! We are so proud of you!

Check out our new paper led by lab member Kenny Mok! We highlight that understanding individual cobamide preferences of bacteria is necessary to understand the critical function of these vitamins in microbial communities. 1/4 journals.asm.org/doi/full/10....
