Excited to share our discovery of archaeal circular, jumbo extrachromosomal elements (up to ~535 kb genomes). One related, 409-kb genome is integrated in CH4-eating Methanoperedens, representing the largest integrative element in Archaea so far! Curious about what they are doing? See the paper

An archaeal genetic code with all TAG codons as pyrrolysine Multiple genetic codes developed during the evolution of eukaryotes and bacteria, yet no alternative genetic code is known for archaea. We used proteomics to confirm our prediction that certain archae...

Red seaweed supplementation suppresses methanogenesis in the rumen, revealing potentially advantageous traits among hydrogenotrophic bacteria - Microbiome Background Macroalgae belonging to the genus Asparagopsis have shown to reduce methane (CH4) production during rumen fermentation, while increasing feed efficiency when added to the feed of cattle. Ho...

We are thrilled to announce our latest publication in the Microbiome journal in collaboration with

Newest preprint from the group on megaplasmids in E. coli led by @assemblerag.bsky.social. In addition to our findings in metagenomic datasets, we identified an RNA-seq project from a giant panda gut sample with evidence of megaplasmids. We would like to include the data creators in our study.

Most plasmids described in E. coli are small compared to the megaplasmids we identified here! Check out the preprint if you want to learn about these mysterious large elements and their potential functions 🧬. I’m very grateful to have had the opportunity to work on this in @banfieldlab.bsky.social

Many of you gave me so much encouragement when I posted here earlier about my 10 year long passion project to make a microbial map of the ocean. Pinch me because I can't believe I get to update you that today that research was published in the journal SCIENCE! @science.org

🥳🥳 Our work exploring the core microbiomes of stable cyanobacterial communities is now out in the @isme-microbes.bsky.social Journal!!! Excellent work by @andrejakust.bsky.social and company!

🚨 Fresh from the press! We created and analyzed over 100 in vitro cyanobacterial consortia using well-characterized model cyanobacterial hosts to better understand how cyanobacteria recruit and interact with their microbiomes.
