📢 New preprint is out on bioRxiv 📢:
How much does virome prep influence our view of the human gut virome?
Short answer: a lot.
Long answer:
doi.org/10.1101/2025...
Different methods lead to distinct community structures, richness, and major virus-host abundance patterns.

Very happy to share our recent work @cultivarium.bsky.social on genetic tools for Ideonella sakaiensis, a (Betaproteo-)bacterium that degrades PET plastic.
We identified a plasmid vector for the strain and generated a large RB-TnSeq library, screening for genes impacting plastic degradation.
