Project description:(Meta)proteomics analyses were performed with cells collected from the Sab enrichment culture grown with N2O. Growth of Desulfitobacterium sp. strain Sab5 only occurred when N2O was supplied as electron acceptor, and biomass from cultures grown without N2O was not included in the analysis. Comparative proteomics analyses were performed with axenic Sporomusa acidovorans DSM3132 T cells grown with and without N2O.
