Together, our findings reveal that organosulfur metabolism is an active and conserved feature of shallow-water chemosynthetic symbioses.
This expands our understanding of how such partnerships function in low-sulfide, DMSP-rich sediments.

We also found that the host encodes a methanethiol oxidase (mtoX-like) gene, expressed in the epidermis.
This suggests a potential host–symbiont metabolic handoff, where symbionts produce methanethiol and the host detoxifies it, maintaining redox balance within the association.

Using metagenomics and transcriptomics, we identified genes for:
• DMSP demethylation and cleavage
• DMS oxidation and DMSO reduction
• Methanethiol oxidation
These pathways form an integrated network that links sulfur, carbon, and nitrogen metabolism among different symbionts.

Kicking off the Euro C1 Conference in Bremen at the @mpimarinemicrobio.bsky.social!
The team was ready, the welcome desk was set, and the lecture hall was prepped - great energy from the start! Excited to dive into two days of inspiring talks, discussions, and connections in the C1 community.
