Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

The atmosphere has recently been recognized as a major source of energy sustaining life.
Diverse aerobic bacteria oxidize the three most abundant reduced trace gases in the …

Soils sustain an immense diversity of microbes, which, to a large extent, remains
unexplored. A range of novel methods, most of which are based on rRNA and rDNA …

Methane is an important greenhouse gas and microbes in the environment play major roles
in both global methane emissions and terrestrial sinks. However, a full mechanistic …

The oxidation of methane by methane-oxidising microorganisms is an important link in the
global methane budget. Oxic soils are a net sink while wetland soils are a net source of …

Life evolved and flourished in the absence of molecular oxygen (02). As the 02 content of
the atmosphere rose to the present level of 21% beginning about two billion years ago …

Stable isotope probing (SIP) is a technique that is used to identify the microorganisms in
environmental samples that use a particular growth substrate. The method relies on the …

Chemical taxonomy based upon the composition of lipids is widely applied to investigate
microbial communities and fatty acids have recently been employed to connect soil …

In the past few years, the field of methylotrophy has undergone a significant transformation
in terms of discovery of novel types of methylotrophs, novel modes of methylotrophy, and …

The use of biomarkers in combination with stable isotope analysis is a new approach in
microbial ecology and a number of papers on a variety of subjects have appeared. We will …
