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 …

Literature frequently mentions increasednitrite concentrations along with itsinhibitory effect
towards bacteria and aquaticlife. Nitrite accumulation has been studied fordecades, and …

Background According to the Intergovernmental Panel on Climate Change (IPCC) 2007,
natural wetlands contribute 20–39 % to the global emission of methane. The range in the …

During an experiment in two laboratory-scale enclosures filled with lake water (130 liters each)
we noticed the almost-complete lysis of the cyanobacterial population. Based on electron …

Chemolithotrophic nitrifying bacteria are dependent on the presence of oxygen for the
oxidation of ammonium via nitrite to nitrate. The success of nitrification in oxygen-limited …

Plant growth in waterlogged soils may be greatly affected by reduced minerals such as
ammonium, manganous and ferrous ions, and sulphide. A more detailed description is given of …

Oxygen-releasing plants may provide aerobic niches in anoxic sediments and soils for
ammonia-oxidizing bacteria. The oxygen-releasing, aerenchymatous emergent macrophyte …

The absence of nitrification in soils rich in organic matter has often been reported. Therefore,
competition for limiting amounts of ammonium between the chemolithotrophic ammonium-…

Correlations between the biomass of phytoplankton and the biomass of bacteria and between
the biomass of bacteria and the biomass of protozoans suggest that there is coupling …

In nature, ammonia-oxidizing bacteria have to compete with heterotrophic bacteria and
plants for limiting amounts of ammonium. Previous laboratory experiments conducted with …
