Organosulfur cycling in the multi-partner symbiosis between lucinid bivalves, sulphur-oxidizing symbionts, and Endozoicomonas Organosulfur compounds play an important role in chemotaxis, stress protection, and nutrition in many marine symbioses. Lucinidae, an ancient and species-rich family of marine bivalves, host chemosynt...

Genomic prediction of collaborative DMSP degradation is consistent with live incubations of the holobiont. The addition of antibiotics results in higher DMSP concentrations. Symbionts may cooperate to degrade excess DMSP, potentially protecting the host from pathogenic bacteria.

We identified previously unrecognised microbial partner in lucinid symbioses (Endozoicomonas) and describe potential metabolic interactions with both the host and the sulphur-oxidising symbionts, highlighting the capacity of these widespread associations to influence global organosulfur cycling.

We integrated field measurements, genomics, transcriptomics, and experimental assays to investigate organosulfur cycling in three lucinid species from temperate and tropical environments.

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.

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!

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 ⚡🦠.

Thanks! Very sweet of you. ☺️

Congratulations! 😊

Huge congratulations! 🎉

Thank you, Jill! Your guidance as my PhD supervisor played an important role in this achievement. I truly appreciate it! 😊

Huge thanks to @cemau.bsky.social for being the perfect host institution for my project!

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!

Oh wow! Somehow I have never came across this type of symbiosis. I’m mindblown. 😍 Thank you for sharing and congratulations on the great work😊

pH-FISH: coupled microscale analysis of microbial identity and acid–base metabolism in complex biofilm samples - Microbiome Background Correlative structural and chemical imaging of biofilms allows for the combined analysis of microbial identity and metabolism at the microscale. Here, we developed pH-FISH, a method that co...

🌟 Exciting news! Our latest collaborative research with team @aarhusuni.bsky.social introduces pH-FISH, a novel technique combining pH ratiometry and FISH to simultaneously unravel microbial identity and local biofilm pH. 🔬 🧪 #MicroSky

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.

“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.

The Parkinson’s disease drug entacapone disrupts gut microbiome homoeostasis via iron sequestration Nature Microbiology - Entacapone, a Parkinson’s disease medication, sequesters iron resulting in a selective inhibition of gut microbial activity.

Our study on drug-gut microbiome interactions is out!
🦠💊

We show that the #Parkinson's drug entacapone induces iron deficiency in microbes, leading to selective inhibition of microbial activity.

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 😱
