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/...

Methanogenesis pathways and methane oxidation in two clear-water and two turbid-water urban ponds in Brussels (Belgium) - Aquatic Sciences Ponds are a large source of atmospheric methane (CH4), a potent greenhouse gas, resulting from the net balance between input from sedimentary methanogenesis and removal by CH4 oxidation (MOX). Here, w...
