The understanding of nitrogen (N) cycling in forest ecosystems has undergone a major shift
in the past decade as molecular methods are being used to link microorganisms to key …

Nitrification is the microbial conversion of reduced forms of nitrogen (N) to nitrate (NO3−),
and in fertilized soils it can lead to substantial N losses via NO3− leaching or nitrous oxide …

For more than 100 years it was believed that bacteria were the only group responsible for
the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative …

Soil emissions are largely responsible for the increase of the potent greenhouse gas nitrous
oxide (N2O) in the atmosphere and are generally attributed to the activity of nitrifying and …

A mesophilic, neutrophilic and aerobic, ammonia-oxidizing archaeon, strain EN76T, was
isolated from garden soil in Vienna (Austria). Cells were irregular cocci with a diameter of …

It was hypothesized that seasonality and resource availability altered through tree girdling
were major determinants of the phylogenetic composition of the archaeal and bacterial …

Biochar amendments have frequently been reported to alter microbial communities and
biogeochemical processes in soils. However, the impact of biochar application on bacterial …

The dominant pools of C and N in the terrestrial biosphere are in soils, and understanding
what factors control the rates at which these pools cycle is essential in understanding soil …

Ammonia‐oxidizing bacteria (AOB) have long been considered key to the removal of
nitrogen in activated sludge bioreactors. Culture‐independent molecular analyses have …

Crucial steps in geochemical cycles are in many cases performed by more than one group
of microorganisms, but the significance of this functional redundancy with respect to …
