Pleased to share this work on cable bacteria. We demonstrate that E.aureum GS, a freshwater cable bacterium, can use extracellular electron transfer to gain energy in anoxic conditions. Many thanks to @leodigel.bsky.social , @ianpgm.bsky.social and other coauthors at @cemau.bsky.social

Hey ISMET member ✋
Did you think we could use a new website too?
Well here it is: www.is-met.org.

It was a pleasure working with @ismetsociety.bsky.social to make their website more engaging and interesting for their members.

Do you also have a website that could use some polishing?

A Gram-positive bacterium can simultaneously reduce oxygen and iron under oxic conditions

Iron reduction under oxic conditions by Microbacterium deferre sp. nov. A1-JKT - Nature Communications
In this study, the authors show that Microbacterium deferre A1-JK, a newly isolated Gram-positive bacterium, simultaneously reduces oxygen and iron under oxic conditions, revealing unexpected microbial metabolic flexibility with implications for biogeochemical cycling.

Recent research has highlighted the ability of some microbes to simultaneously respire aerobically and anaerobically, a flexible strategy that reshapes our understanding of microbial metabolism. In my latest article for @asm.org , I explore this phenomenon.

If you are interested in reading the "Behind the paper"story of how we discovered this electroactive microbe and simultaneous aerobic-anaerobic respiration, have a look at our blog post in the Nature Research Communities here: communities.springernature.com/posts/simult...

Thrilled to share our latest work on simultaneous aerobic-anaerobic metabolism enabled by extracellular electron transfer. The microbe in focus, Microbacterium deferre A1-JK, was isolated from the oxic-anoxic sediment interface.

Having mostly done experiments in the lab, I finally sat down with @ianpgm.bsky.social to learn some bioinformatics. I can now see why people do science on their computers - you don't need to get your hands dirty with mud. 😅😅😅

Great to meet two of my amazing mentors at once at the Electromicrobiology conference. Two of the best people I had to the pleasure to work with. Thanks a lot @ianpgm.bsky.social and Lucinda for everything.

🚀🔬 Excited to take part in #ScienceIsWonderful festival at Africa Museum, Tervuren, Belgium. I'll present a #ScienceShow on electric cable bacteria. We also have experiments & games for all, with free entry: europa.eu/!F49vCw #MarieCurieFellowship #cablebacteria

Last year I had the pleasure of working with Antonio Castellano-Hinojosa, who visited Aarhus to use metagenomics and metatranscriptomics to characterise a microbial fuel cell treating saline wastewater. The result of that collaboration has just been published: authors.elsevier.com/a/1kk9L14Z6t...

One of the most rewarding aspects in academia is working with bachelor’s students at the start of their research journey. Their enthusiasm, curiosity, and eagerness to learn are fantastic to see. Glad to be working with them on their projects. 🙏

It was wonderful attending the first A-ISMET conference in Egypt. Great to see the ISMET society going global. The cultural trip exploring Egypt's ancient civilization was fantastic. Plus there were some nice cable bacteria in the Red Sea!
