Inhibition of methane oxidation by nitrogenous fertilizers in a paddy soil
Nitrogenous fertilizers are generally thought to have an important role in regulating methane oxidation. In this study, the effect of ammonium on methane oxidation activity was investigated in a paddy soil using urea at concentrations of 0, 50, 100, 200, and 400 μg N per gram dry weight soil (N/g.d.w.s) and ammonium sulfate at concentrations of 0, 50, and 200 μg N/g.d.w.s. The results of this s...
متن کاملResponse of Nitrosospira sp. strain AF-like ammonia oxidizers to changes in temperature, soil moisture content, and fertilizer concentration.
Very little is known regarding the ecology of Nitrosospira sp. strain AF-like bacteria, a unique group of ammonia oxidizers within the Betaproteobacteria. We studied the response of Nitrosospira sp. strain AF-like ammonia oxidizers to changing environmental conditions by applying molecular methods and physiological measurements to Californian grassland soil manipulated in the laboratory. This s...
متن کاملPolyclonal antibodies recognizing the AmoB protein of ammonia oxidizers of the beta-subclass of the class Proteobacteria.
A 41-kDa protein of Nitrosomonas eutropha was purified, and the N-terminal amino acid sequence was found to be nearly identical with the sequence of AmoB, a subunit of ammonia monooxygenase. This protein was used to develop polyclonal antibodies, which were highly specific for the detection of the four genera of ammonia oxidizers of the beta-subclass of Proteobacteria (Nitrosomonas, including N...
متن کاملRadioactive fingerprinting of microorganisms that oxidize atmospheric methane in different soils.
Microorganisms that oxidize atmospheric methane in soils were characterized by radioactive labelling with (14)CH(4) followed by analysis of radiolabelled phospholipid ester-linked fatty acids ((14)C-PLFAs). The radioactive fingerprinting technique was used to compare active methanotrophs in soil samples from Greenland, Denmark, the United States, and Brazil. The (14)C-PLFA fingerprints indicate...
متن کاملThe large-scale distribution of ammonia oxidizers in paddy soils is driven by soil pH, geographic distance, and climatic factors
Paddy soils distribute widely from temperate to tropical regions, and are characterized by intensive nitrogen fertilization practices in China. Mounting evidence has confirmed the functional importance of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in soil nitrification, but little is known about their biogeographic distribution patterns in paddy ecosystems. Here, we used barcoded pyrose...
