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...

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.

📣 Methane causes ~30% of global warming, & despite emissions reductions, a major gap will remain by 2050. #BiologicalMethaneRemoval is one of the most promising ways to close that gap. With @sparkclimate.bsky.social, we convened 30 experts, resulting in 22 problem statements.

Isolation of Crenothrix bacteria reveals the distinct ecophysiologies of filamentous methanotrophs and adaptations to redox stress At the dawn of modern microbiology, Cohn observed abundant filamentous bacteria in drinking water wells that he named Crenothrix polyspora.
