Underground happy hour? Excited to share our discovery of a new symbiosis between subsurface bacteria and archaea bridged by syntrophic transfer of the smallest alcohol—methanol! @Nature Work led by a former student Huang Yan, congratulations! https://t.co/icc1raepU6

Our latest preprint is out! This paper led by @SukhwanYoon uncovers a new process controlling the global hydrogen and nitrogen cycles, i.e. the direct coupling of hydrogen oxidation and ammonification. A beautiful combination of isolation, bioreactor, and systems biology studies.

Our new discovery of hydrogenotrophic DNRA now in biorxiv! Two distinct Campylobacterota isolates found to couple hydrogen oxidation with DNRA, challenging traditional C:N ratio paradigm. https://t.co/QYBOXJjrzc

SeqCode to provide a framework for organizing and naming uncultured taxa, which addresses an important issue in microbiology that has become very messy over recent years. home page: https://t.co/OsbCEJc2yS Hedlund et al. Nature Microbiology 2022: https://t.co/jtr0qiIgXo

Nature Microbiology - SeqCode is the result of a community effort to unify nomenclature for uncultured and cultured prokaryotes using genome sequences.

Most are probably aware of the disagreement between ICSP/ICNP and SeqCode, but if this hasn’t made it your way yet, please take a moment to read up on both and discuss. Both big efforts trying to support our field, discussing their pros/cons is critical. Links coming up!

Hoping this helps stimulates even deeper research on eukaryogenesis and constructive discussion between ICSP and SeqCode on a solution for prokaryotic taxonomy and nomenclature and protecting culture collections, both foundations of microbiology research!
