Journal ArticleDOI
Effects of temperature and fertilizer on activity and community structure of soil ammonia oxidizers.
TL;DR: Ammonium oxidizers are able to adapt to soil conditions by changes in the community structure if sufficient time (several weeks) is available, in particular as community shifts were also observed in the soil slurries, in which ammonium concentrations and pH were better controlled.
Journal ArticleDOI
Effect of soil ammonium concentration on N2O release and on the community structure of ammonia oxidizers and denitrifiers.
TL;DR: A community shift occurred for denitrifier populations based on T-RFLP analysis of nirK genes encoding copper-containing nitrite reductase with incubation at medium and high ammonia concentrations, probably the consequence of the increased supply of oxidized nitrogen through nitrification.
Journal ArticleDOI
Patterns of Community Change among Ammonia Oxidizers in Meadow Soils upon Long-Term Incubation at Different Temperatures
Sharon Avrahami,Ralf Conrad +1 more
TL;DR: It is concluded that ammonia oxidizer populations are influenced by temperature, and it is confirmed that N fertilizer also influences the community structure of ammonia oxidizers.
Journal ArticleDOI
Methane-oxidizing bacteria in a California upland grassland soil: diversity and response to simulated global change.
TL;DR: Comparison of amino acid residues and rates of nonsynonymous versus synonymous nucleotide substitution in these novel lineages suggests that the pmoA genes in these clades code for functionally active methane monooxygenases.
Journal ArticleDOI
Response of Nitrosospira sp. Strain AF-Like Ammonia Oxidizers to Changes in Temperature, Soil Moisture Content, and Fertilizer Concentration
TL;DR: The response of Nitrosospira sp.
