Understanding energy and hydrogen metabolism in sulfate-reducing bacteria
| Resumo: | "Molecular hydrogen (H2) is a promising alternative energy carrier due to its high energy content and absence of greenhouse gas emissions, but its natural abundance is low and it must be generated, usually through energy-intensive processes. Sulfate-reducing prokaryotes (SRP) are interesting microorganisms for H2 production, as they typically have many hydrogenases, the enzymes responsible for producing and/or oxidizing H2. SRP are found in anoxic environments, where they play a pivotal role in both the carbon and sulfur cycles. These microorganisms use highly conserved respiratory membrane complexes to couple the oxidation of H2 or carbon compounds with the dissimilatory reduction of sulfate or sulfite.(...)" |
