✅ MISO outperforms the chemical reaction under environmentally relevant sulfide concentrations

✅ Key MISO genes are evolutionarily conserved in the family Desulfurivibrionaceae and widely distributed across marine, freshwater, terrestrial, and engineered environments

Main findings

✅ The genetic capacity for sulfur compound oxidation and iron(III) oxide respiration co-occurs in genomes from 37 phyla

✅ Desulfurivibrio alkaliphilus grows autotrophically by oxidizing dissolved sulfide or iron monosulfide (FeS) to sulfate with ferrihydrite as electron acceptor

We now show that this redox reaction also powers 🔋🔌 a new chemolithoautotrophic lifestyle of anaerobic microbes 🦠🧫

Many thanks @anne-daebeler.bsky.social and @roeyangel.bsky.social for being great hosts during my 3-month stay at your institute at the Biology Centre CAS 🤩

I had a wonderful time! Greetings to your colleagues and team members 👋🙌

Remembering
Theodor Escherich 🕯️

✝️ February 15, 1911

A pioneer of microbiome science who discovered 🧫🔬the gut 💩bacterium Escherichia coli 🦠in 1885.

He was a pediatrician at the Universities of Graz and Vienna and rests in peace at the Hernals cemetery in Vienna 🇦🇹
