Thank you!!

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/...

Diversity, ecology, cell biology and evolution of the Asgard archaea - Nature Reviews Microbiology The Asgard archaea have become a cornerstone of archaeal research, particularly for studies aiming to unravel the origin and early evolution of eukaryotes.

Viruses in marine sediments: a review of their effect on biogeochemistry and microbial interactions | Applied and Environmental Microbiology In the ocean, viruses are known to mediate the carbon cycle, keeping dissolved organic carbon (DOC) in the microbial loop and preventing its movement into secondary consumers (1). However, few direct ...

New paper out! We sat down and compiled all viral work in marine sediments. The water column has been getting a second look for viral interactions, its time for sediment to have the same!
