Check out this awesome resource for all your future microbial #genome analyses: #GlobDB is the to date most complete genome database available! Developed by @daanspeth.bsky.social and colleagues 🧪🦠🧬🖥️
Our paper describing the GlobDB is now published in @bioinfoadv.bsky.social doi.org/10.1093/bioa... The GlobDB is the largest species dereplicated genome database currently available, containing 306,260 species representatives. More information on globdb.org 1/5 🖥️🧬🦠
Interested in #nitrification? Check-out this new paper driven by the #MichaelPester group focussing on nitrification-driven chemolithoautotrophy in oligotrophic lake hypolimnia. Freshwater AOA contribute only a minor part to dark DIC fixation in these systems. academic.oup.com/ismecommun/a...
Spatiotemporal and temperature-dependent disconnect between ammonia oxidation and dark DIC fixation in deep oligotrophic Lake Constance
Abstract. Deep oligotrophic lakes hold over 80% of global lake water. In their hypolimnion, ammonia oxidation (the first step of nitrification) and non-pho

#Urea: The Hidden Fuel for Ocean Microbes 🦠🌊 Study in @natcomms.nature.com shows how #ammonia-oxidizing #archaea thrive in nutrient-poor waters: Urea is a major energy source for #AOA in the open #ocean, while coastal AOA prefer #ammonium. www.mpi-bremen.de/en/Urea-The-...

A short preprint describing the GlobDB is now on arXiv: arxiv.org/abs/2506.11896 If you find the resource useful, please also check globdb.org for info on how to cite the underlying resources and tools.
I'm happy to announce the latest release of the GlobDB, available at globdb.org. The GlobDB is a database of "species dereplicated" microbial genomes, and as of release 226 contains twice the number of species-representative genomes (306,260) than the latest GTDB release.
