Quantitative analyses of the abundance and composition of ammonia-oxidizing bacteria and ammonia-oxidizing archaea of a Chinese upland red soil under long-term fertilization practices.
The abundance and composition of soil ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) were investigated by using quantitative real-time polymerase chain reaction, cloning andExpand
Abundance and composition of ammonia-oxidizing bacteria and ammonia-oxidizing archaea communities of an alkaline sandy loam.
The abundance and composition of soil ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) communities under different long-term (17 years) fertilization practices were investigatedExpand
Nitrification driven by bacteria and not archaea in nitrogen-rich grassland soils
The oxidation of ammonia to nitrate, known as nitrification, is a key process in the nitrogen cycle. Real-time polymerase chain-reaction measurements show that nitrification is driven by bacteriaExpand
Ammonia-oxidizing archaea have more important role than ammonia-oxidizing bacteria in ammonia oxidation of strongly acidic soils
Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing bacteria (AOB) to ammoniaExpand
Ammonia-oxidizing bacteria and archaea grow under contrasting soil nitrogen conditions.
Nitrification is a key process of the nitrogen (N) cycle in soil with major environmental implications. The recent discovery of ammonia-oxidizing archaea (AOA) questions the traditional assumption ofExpand
Ammonia-oxidizing archaea: important players in paddy rhizosphere soil?
The diversity (richness and community composition) of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in paddy soil with different nitrogen (N) fertilizer amendments for 5 weeks were investigatedExpand
Autotrophic ammonia oxidation by soil thaumarchaea
Nitrification plays a central role in the global nitrogen cycle and is responsible for significant losses of nitrogen fertilizer, atmospheric pollution by the greenhouse gas nitrous oxide, andExpand
Microbial regulation of terrestrial nitrous oxide formation: understanding the biological pathways for prediction of emission rates.
The continuous increase of the greenhouse gas nitrous oxide (N2O) in the atmosphere due to increasing anthropogenic nitrogen input in agriculture has become a global concern. In recent years,Expand
Effects of Cd and Pb on soil microbial community structure and activities
Background, aim, and scopeSoil contamination with heavy metals occurs as a result of both anthropogenic and natural activities. Heavy metals could have long-term hazardous impacts on the health ofExpand
Current insights into the autotrophic thaumarchaeal ammonia oxidation in acidic soils
Recent studies of ammonia-oxidizing archaea (AIDA) suggested their significant contributions to global nitrogen cycling, and phylogenetic analysis categorized AOA into a novel archaeal phylum, theExpand
