The global methane cycle: recent advances in understanding the microbial processes involved

Conrad, Ralf·2009·Environmental Microbiology Reports

Abstract

Summary: The global budget of atmospheric CH 4 , which is on the order of 500–600 Tg CH 4 per year, is mainly the result of environmental microbial processes, such as archaeal methanogenesis in wetlands, rice fields, ruminant and termite digestive systems and of microbial methane oxidation under anoxic and oxic conditions. This review highlights recent progress in the research of anaerobic CH 4 oxidation, of CH 4 production in the plant rhizosphere, of CH 4 serving as substrate for the aquatic trophic food chain and the discovery of novel aerobic methanotrophs. It also emphasizes progress and deficiencies in our knowledge of microbial utilization of low atmospheric CH 4 concentrations in soil, CH 4 production in the plant canopy, intestinal methanogenesis and CH 4 production in pelagic water.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
