Neat work from Krasny lab dissecting the impact of sublancin on a transporter protein of B.subtilis and how SunI confers resistance

Maxence also mentions two open post doc positions connected to his ERC StG project in 2027 #openPostDocposition

Nice to see the number of happy ecologists growing in Tam’s group
#EMBOBacNet

Tam finishes with their ongoing experiments on Myxococcus fungus interactions
#EMBOBacNet

Tam mentions that genes involved in predation are overrepresented in the different networks of Myxococcus - connecting microbial ecology to molecular cell biology

Tam now continues their long time work on Myxococcus prey killing

#EMBOBacNet

Tam starts with ecological approach to follow Myxococcus abundance in a vineyard vs nearby forrest (about the last 300 years) demonstrating how Myxococcus is embedded in the forrest soil environment, while less in the vineyard soil, despite of higher abundance in vineyard

#EMBOBacNet

Alex also presents how essential genes of different phages change depending on the host strains (e.g. different EPEC isoltes)

#EMBOBacNet

Alex highlights how they identified novel biological functions for viral genes, not only in model phages, but also in new phage isolates

#EMBOBacNet

Alex aims to identify essential genes within the phage genomes, see details in their bioRxiv (coming soon in @natmicrobiol.nature.com)
www.biorxiv.org/content/10.1...

#EMBOBacNet

Alex highlights the BASEL (BActeriophage SElection for your Laboratory) phage collection including 106 phages with high diversity, useful for screening different types of phages, e.g. for phage defense systems
