One of my favorite papers of past few years!
New @fwf-at.bsky.social CoE Microplanet study in ISME Journal! CoE Key Researcher Alex Loy and team @loyteam.bsky.social @cemess.bsky.social @univie.ac.at find rumen bacteria that degrade a plant- and algal-derived sulfosugar, might help limit methane production. doi.org/10.1093/isme...
By characterizing the structure and function of a methylthio-alkane reductase system, researchers could open avenues for using bacteria to produce ethylene and more. 🖥️ 🧬

Long in the making, great to see the study on line at @femsmicro.org A novel North Sea ammonia-oxidizing archaeon Nitrosarchaeum marinum leverages a high abundance of transport systems to grow over a wide salinity range. #microbiology @ribesresearch.bsky.social academic.oup.com/femsec/artic...
Excited to announce our new journal from @isme-microbes.bsky.social ISME Host Microbe is live and now accepting submissions. Look forward to receiving your papers! #Microsky 🧫 🦠
Abstract. Sulfoquinovose, a sulfonated sugar derived from the thylakoid membrane lipid sulfoquinovosyl diacylglycerol, is abundant in photosynthetic organi
New paper out in Nature Comms 🎉
Congrats to first author @sekid.bsky.social & thanks team & collaborators
We show that B. bifidum & E. coli can cooperate in the breastfed infant gut through nutrient cross-feeding, helping shape early-life microbiome development 🦠👶

Rumen microbiota are essential for cattle husbandry, providing energy and protein through fermentation. However, this symbiotic process also produces methane as a byproduct, representing both a loss of feed energy for the animal and a major source of greenhouse gas emissions. A new study now uncovers the identity and metabolism of rumen bacteria that degrade a ubiquitous plant- and algae-derived sulfosugar, revealing a previously unrecognized process that may help limit methane production.
Escherichia coli is widespread in healthy breastfed infants, yet its ecological role is unclear. Here, the authors provide insights into the mechanisms supporting its persistence and co-existence with...

Out Now! Skin androgens regulate Staphylococcus aureus pathogenicity via quorum sensing #MicroSky

Nature Microbiology, Published online: 27 February 2026; doi:10.1038/s41564-026-02261-2Testosterone produced by skin cells enhances Staphylococcus aureus pathogenicity by activating quorum sensing, and a stereoisomer of testosterone that blocks this interaction inhibits bacterial cytotoxicity towards human cells.
