Methane-utilizing bacteria (methanotrophs) are a diverse group of gram-negative bacteria
that are related to other members of the Proteobacteria. These bacteria are classified into …

Production and consumption processes in soils contribute to the global cycles of many trace
gases (CH4, CO, OCS, H2, N2O, and NO) that are relevant for atmospheric chemistry and …

Although diazotrophs are important in the nitrogen (N)-cycle and contribute to the pool of
plant available N, the population response to long-term inorganic fertilization is largely …

Natural gas is a mixture of low molecular weight hydrocarbon gases that can be generated
from either fossil or anthropogenic resources. Although natural gas is used as a …

Soil acidification can be accelerated by intensive farming or prevented by sustainable
management practices. Soil acidification in a managed agricultural production system is …

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 …

Landfill gas containing methane is produced by anaerobic degradation of organic waste.
Methane is a strong greenhouse gas and landfills are one of the major anthropogenic …

Molecular oxygen is one of the most important reactants in biogeochemical cycles. Due to its
low solubility in water, the consumption of oxygen leads to the development of oxic–anoxic …

Besides water vapour, greenhouse gases CO2, CH4, O3 and N2O contribute~ 60%, 20%,
10% and 6% to global warming, respectively; minor contribution is made by …

The global intensification of livestock production resulted in potentially higher emissions of
ammonia, odour, particulate matter (PM) and greenhouse gases (nitrous oxide and …
