Microbes make methane from coal

Microbial Physiology Methane associated with coal beds is an important global resource of natural gas. Much of the methane in coal comes from microbial methanogenesis. Mayumi et al. characterized a strain of Methermicoccus shengliensis that, unexpectedly, is capable of making methane from the dozens of methoxylated aromatic compounds found in a variety of coal types (see the Perspective by Welte). Isotope tracer experiments showed that this organism could also incorporate carbon dioxide into methane. Science , this issue p. [222][1]; see also p.
