Biochar is obtained by pyrolyzing biomass and is, by definition, applied in a way that avoids
its rapid oxidation to CO2. Its use in agriculture includes animal feeding, manure treatment …

Methane is the final product of the anaerobic decomposition of organic matter. The
conversion of organic matter to methane (methanogenesis) as a mechanism for energy …

Anaerobic oxidation of methane (AOM) is crucial for controlling the emission of this potent
greenhouse gas to the atmosphere. Nitrite-, nitrate-, and sulfate-dependent methane …

Microbially mediated anaerobic oxidation of methane (AOM) is a key process in the
regulation of methane emissions to the atmosphere. Iron can serve as an electron acceptor …

Petroleum hydrocarbons represent the most frequent environmental contaminant. The
introduction of petroleum hydrocarbons into a pristine environment immediately changes the …

Over the past century a number of models have been developed to explain the vast
stratigraphic distribution of authigenic dolomite. These models include hydrogeological …

Only three biological pathways are known to produce oxygen: photosynthesis, chlorate
respiration and the detoxification of reactive oxygen species. Here we present evidence for a …

Paddy soils make up the largest anthropogenic wetlands on earth. They may originate from
any type of soil in pedological terms, but are highly modified by anthropogenic activities. The …

Methane is the most abundant hydrocarbon in the atmosphere, and it is an important
greenhouse gas, which has so far contributed an estimated 20% of postindustrial global …

Interspecies electron transfer is a key process in methanogenic and sulphate-reducing
environments. Bacteria and archaea that live in syntrophic communities take advantage of …
