Lithosyntrophy: Obligate syntrophy in a phosphite-oxidizing, methanogenic culture | PNAS The anaerobic conversion of organic matter to methane and carbon dioxide typically relies on obligate syntrophic interactions between bacteria and ...

How do you make methane from phosphite? Through interspecies H2 transfer! Our paper on lithosyntrophy is finally published - read about how we resolved the metabolic interactions in this phosphite oxidizing, methanogenic enrichment culture! #phosphorus #methanogenesis www.pnas.org/doi/10.1073/...

#FEMSmicroBlog: Exploring the metabolic activities of microbial methane munchers #FEMSmicroBlog: So-called “microbial methane munchers” have the unique abilities to lower methane emissions from various ecosystems.

Methane is the second most abundant greenhouse gas with a high heat-trapping capacity but a short lifespan in the atmosphere.

So-called “microbial methane munchers” can lower methane emissions from diverse ecosystems, as explored on the new #FEMSmicroBlog. #FascinatingMicrobes

... and others not on bluesky

In a nutshell:
1. CO and H2 oxidizers seem more resilient to long-term warming than CH4 oxidizers
2. In consequence, the soil CO and H2 sink remained strong
3. And of course, more research is needed covering other seasons and biomes

Soil trace gas oxidizers divergently respond to short- and long-term warming The upland soil microbiome is dominated by aerobic bacteria that oxidize atmospheric trace gases, including CO, H2, and CH4. As a result, soils are the largest biological sink for these climate-active...
