Yesterday, Danijel brought all the determination, skill, and a touch of humor to his defense in front of an expert panel: Prof. Mina Bizic (environmental microbiomics, TU Berlin), AProf. Florin Musat (microbial physiology, Aarhus University), chaired by AProf. Peter Stief (microbial ecology, SDU).

What a day yesterday was! 🌟 My PhD student Danijel Jovicic defended his thesis on conductive-particle obligate consortia. It’s been a journey of long days, hundreds of incubations, hours in the anoxic glovebox, and handling cores in anoxic bags on rocking ships. 🛳️ 🌊 Then omics lots of omics! 🧬

These particles wire the smallest e-transfer unit we’ve resolved: a particle-bound partnership moving e- from acetate oxidizers to Methanosarcina to make methane. Our blueprint makes this pathway mappable and model-ready, enabling hotspot detection and sharpening emission predictions models. 🌊

Why it matters?

🔋 Conductive particles wire sediments. Geoconductors (black carbon, iron minerals) are rising with wildfire, erosion, combustion, and glacier melt; e.g., in Arctic glacial-melt sediments, black carbon can approach 100% of TOC.

🦠 Novel electrotroph. A type II Methanosarcina primed for direct electron uptake (MmcA + Rnf/Fpo/HdrDE) and CO₂-reducing methanogenesis.

👉 Field markers. We provide diagnostic markers (distinct PCC variants, MmcA) for surveys.

What is exciting about our findings?

🦠 Novel electrogens & EET conduits. A new genus outside Geobacteraceae: Ca. Geosyntrophus acetoxidans with a minimal EET conduit (1 PCC, 47 MHCs, e-pili). Plus a Lentimicrobium with giant PCC-like clusters.

1/3 Electricity from air! In the top journal Nano Energy today, we report the first fuel cell that makes power from air alone. We achieved this by using the enzyme Huc to oxidize ambient hydrogen. This results in a continuous low-level power from air and higher outputs with industrial waste gases.

Masterpiece paper from Ning, Perran, Amelia and co! Great mix of field-based geochemistry, laboratory manipulations, methanogen cultivation, and isolate / environmental genomics. An unexpected feedback between eutrophication and climate change that could shake up how we think about methane budgets.

Check this nice first first-author paper by Ning Hall—now out in Nature Geoscience! Our team had a blast supporting Ning on the isolation workflow, and a few of the standout Methanococcoides strains even trace back to our Danish waters. 🌊

📖 Why this study is so cool: these surprisingly tough, methylotrophic Methanosarcinaceae (Methanococcoides) shrug off oxygen pulses, settle in oxic sediments, and feast on seaweed and seagrass metabolites—driving methane emissions in places we never thought anaerobic methanogens could thrive.
