Happy to share our new paper on cable bacteria. Motivated by the lack of pure cultures, we developed a standardized artificial sediment system that supports repeated cultivation of freshwater and marine cable bacteria under controlled conditions. Link: doi.org/10.1093/isme...

Artificial sediments enable reproducible cultivation and recapitulate ecological interactions of cable bacteria

Abstract. Cable bacteria are filamentous microbes that couple sulfide oxidation to oxygen reduction over centimeter distances via long-distance electron tr

It’s exciting to see converging evidence across systems! 😀 Alongside the new work on gutless worms, our study shows that organosulfur cycling is also essential in lucinid holobionts. Lucinid host provides DMSP to its symbionts, sulphur-oxidising Thiodiazotropha and, a new member, Endozoicomonas.

New preprint! We explore how gutless marine worms and their bacterial symbionts use organosulfur compounds like DMSP and DMS - key molecules in marine sulfur cycling. Our results show that these compounds support carbon and energy metabolism in the Olavius algarvensis symbiosis.

Respiratory endosymbionts, that allow their ciliate hosts to breathe nitrate instead of (or in addition to) oxygen are frequent members of the wastewater microbiome. 🦠 🖥️🧬 Great to see this work by @louison-nicolas.bsky.social published in ISME coummuncations! doi.org/10.1093/isme...

After an interesting and very exciting journey with my friends, we showed that this little guy (Microbacterium deferred A1-JK) not only produces electricity but also does it while breathing oxygen and uses a cross-Gram (Gram- &Gram+ genes combined) hybrid mechanism to do this ⚡🦠.

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. Link: www.nature.com/articles/s41...

As a science-loving girl growing up in Poland, Maria Skłodowska-Curie was my role model, so much so that I once portrayed her in a school play! 😅 Now, 15 years later, receiving a positive result on my #MSCA application feels surreal. A full-circle moment I never imagined back then!

“Riftia” is a deep sea vent tubeworm that has no mouth or digestive tract. Rather, it hosts billions of symbiotic bacteria that provide them nutrition. Wildly, they are among the fastest growing organisms on the planet! Our paper examines *how* they pull this off. www.nature.com/articles/s41...

Co-expression analysis reveals distinct alliances around two carbon fixation pathways in hydrothermal vent symbionts - Nature Microbiology

Live tubeworm incubations reveal that chemoautotrophic symbionts regulate the Calvin–Benson–Bassham and reductive tricarboxylic acid pathways to suit geochemistry and metabolism.

It’s true, you only see what you’re looking for: After decades studying chemosynthetic symbionts in clam gills, we realized they colonize the digestive tract too 😱 academic.oup.com/ismej/articl...
