We are hosting a PhD course on volatiles in ecosystems for 30 international PhD students. Today we heard flash talks by all participants, got an introduction to isotopes, a lab tour and a tour in the Botanical Garden of #SNM.

We are thankful for Faculty of Science @ucph.bsky.social for funding.

Has anyone else used Qiagen's PowerProtect solution (now that LifeGuard is unavailable) but with success extracting DNA/RNA from soil samples?

I’m happy to share our recent review published in The ISME Journal! Here, we explore the role of CO and Hβ‚‚ oxidisers in oligotrophic environments. This work was a collaboration with Philippe Constant, Gary King, and @hendrikschaefer.bsky.social.

Hope you enjoy it!

Genomic and metagenomic survey of microbial carbonic anhydrase genes reveals novel clades, high diversity, and biome-specificity Carbonic anhydrase (CA) enzymes catalyze the interconversion of carbon dioxide and bicarbonate with an efficiency exceeded only by superoxide dismutase. CA enzymes have convergently evolved multiple t...

Our new preprint is out! A genomic and metagenomic dive into the diversity of microbial carbonic anhydrases. Huge thanks to the amazing team who made this possible!
