Research by microbiologists @raegas.bsky.social and @cuwelte.bsky.social of @ribesresearch.bsky.social shows that many methane-consuming microorganisms actually prefer carbon monoxide over methane. When carbon monoxide is present, they consume far less methane. 1/2

Carbon monoxide metabolism in freshwater anaerobic methanotrophic archaea - Nature Communications Anaerobic methane-oxidizing archaea mitigate methane emissions in anoxic environments. Here, Egas et al. show that these microbes can also oxidize carbon monoxide, prompting re-evaluation of their cla...

Grab a coffee and enjoy reading up on CO metabolism in methanotrophs!

Big thanks to our collaborators at QUT!

Preprint out!

Anaerobic methanotrophs are key methane oxidizers, but their activity/adaptation under acidic conditions remains unclear. We show that a freshwater ANME adapts to pH stress via shifts in lipid composition and remains metabolically active down to pH 5.65. Expanding the niche of ANME.

Beyond thrilled to share that our study has been published!
This project encompasses years of work, including my thesis research on Asgard archaea in the @archaeal.bsky.social lab at @utmsi.bsky.social and

Our latest preprint: Together with the team of Jan Löwe, @danieltamarit.bsky.social and many others we discovered and characterized several Asgard tubulin genes and propose that microtubule architecture and dynamics evolved in Asgard archaea prior to eukaryogenesis

Great paper, thanks for sharing!

A Cell So Minimal That It Challenges Definitions of Life | Quanta Magazine The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.

A newly discovered archaeal cell has a tiny genome and can’t metabolize biomolecules. It’s upending biologists’ definition of a living thing. “These types of organisms have been found before, but not as extreme as this,” said microbiologist Thijs Ettema.

New preprint out: Although sulfate reduction at pH < 3 is reported in acid mine/rock drainage environments, isolated aSRB have never matched this limit. Using axenic planktonic chemostats plus DNA/RNA and lipid analyses, we demonstrate aSRB activity and underlying physiology at AMD-like pH.

Coincidental and exciting! Anaerobic methanotrophic archaea (ANME) do like carbon monoxide - two independent studies showcasing CO metabolism across freshwater and marine ANME (ANME-2d and -2b).
