Congratulations @daanspeth.bsky.social and the whole team. GlobDB has already been very helpful for several projects at @cemess.bsky.social, and it will no doubt be a useful resource for many microbiologists around the world. Really glad to see it out there.

We have a date for the free-to-attend #anvio workshop and ECR Symposium for 2026, and we look forward to meeting you at the @hifmb.de in Oldenburg, Germany!

Please find more information on the venue, program, and the application form here, and spread the word 😇

A hydrothermal vent on the Mid-Atlantic Ridge. Hot, mineral-rich fluids are distributed throughout the ocean via the dispersion cloud, known as the plume. The photo was taken during the M190 research expedition with the MARUM-QUEST4000 remotely operated vehicle. The arm of the robot holds a temperature lance into the plume to measure the temperature there. Photo: MARUM – Center for Marine Environmental Sciences, University of Bremen.

A new review study shows the invisible transport pathways for #iron through #hydrothermal plumes.

Microbial iron oxide respiration coupled to sulfide oxidation - Nature Genomic and biochemical analyses of prokaryotic sulfur metabolism identify diverse microorganisms with the capacity to oxidize sulfide using iron(iii).

Microbes rock 🎸🤘 with sulfide and iron minerals

I am very excited to share our recent study, which describes a previously unknown microbial energy metabolism ⚡⚡⚡🦠🧫⚡⚡⚡

Phosphite oxidizers 🤝 Methanogens
In our new paper on “Lithosyntrophy” we show that phosphite oxidation drives methanogenesis through interspecies H2 transfer. Lithosyntrophy establishes a novel mechanistic link between the #phosphorus and carbon redox cycles

also the HMM suite for an extensive array of sulfur enzymes is very handy (already used it!) ! :-)

Bacteria that 'breathe' rocks and sulphur. 🦠🧫
An international team of scientists led by #microbiologists @loyteam.bsky.social and Marc Mussmann have uncovered #bacteria that remove toxic sulfide and use iron #minerals for growth. 🧪🧑‍🔬

Modulation of methyl–coenzyme M reductase expression alters the isotopic composition of microbial methane The stable isotopic composition of microbial methane varies substantially, and the underlying causes are debated. In this work, we experimentally controlled the abundance of the central enzyme in meth...

Our story about microbial methane is out! We found that reducing the expression of a key gene of methanogenesis modulates the isotopic composition of the methane:

Sulfur-rich deposits associated with the deep submarine volcano Fani Maoré support broad microbial sulfur cycling communities - Microbiome Background In 2018, the island of Mayotte located in the western Indian ocean, has experienced a seismo-volcanic crisis linked to the birth of an impressive intraplate submarine volcano at the east of...
