Syntrophic Degradation of Cadaverine by a Defined Methanogenic Coculture

Abstract: A novel, strictly anaerobic, cadaverine-oxidizing, defined coculture was isolated from an anoxic freshwater sediment sample. The coculture oxidized cadaverine (1,5-diaminopentane) with sulfate as the electron acceptor. The sulfate-reducing partner could be replaced by a hydrogenotrophic methanogenic partner. The defined coculture fermented cadaverine to acetate, butyrate, and glutarate plus sulfide or methane. The key enzymes involved in cadaverine degradation were identified in cell extracts. A pathway of cad… Show more

“…"Candidatus Contubernalis alkalaceticum," which syntrophically oxidizes acetate, isobutyrate, several alcohols, serine, and fructose, belongs within the family Syntrophomonadaceae (112). An unnamed strain, LC 13D, syntrophically degrades primary amines (cadaverine and putrascine), amino acids, and butyrate (84). Stable-isotope probing and substrate enrichment experiments implicate phylotypes related to Pelotomaculum/Cryptanaerobacter and Epsilonproteobacteria in syntrophic benzene degradation under sulfate-reducing conditions (30,41,45) and new lineages in the Firmicutes and Deltaproteobacteria in syntrophic fatty acid metabolism (13, 28).…”

“…Others have shown similar increased metaproteomic signal in fatty acid metabolism with starch enrichment [1,58]. Butyrate is produced via multiple pathways including the acetyl-CoA [59][60][61], glutarate [62][63][64], 4-aminobutyrate [65][66][67], and lysine pathways [68][69][70]. The dominant pathway associated with butyrate production is the acetyl-CoA pathway, which was higher in the microbiome in the WG enriched diet [57,59,[71][72][73][74].…”
