Just wrapped up inspiring days of science and networking at the VAAM Workshop “Biology of Bacteria Producing Natural Products” in Berlin!
Our team’s first conference ended on a high note — 2nd prize for best poster! 🥈🥳
Thanks to the organizers @niedermeyer-lab.bsky.social for a fantastic meeting. 🙏

We are hiring! We are going to use some really, really cool new techniques to look at the chemical and spatial dynamics of how the plant micobiome takes shape and what it means. Join us! Apply online until 20th Oct here: www.microverse-cluster.de/files/conten...

Cool feature! Just hope no one tries to draw the structures from the image 😅

🚀 SIRIUS v6.3 is here!

🚨getphylo workshop announcement🚨
(Please share!)

Are you interested in building genome-scale phylogenies - fast? Or want to explore the evolution of gene clusters? Then getphylo might be the tool for you!

I will be running online workshops on the 26th and 27th May. 🧪💻 1/3

I agree, SIRIUS is a great tool and can be helpful for that task! You can also add your (expected) macrolide structures in SIRIUS, in case they are not in public databases yet.
