Depth-related distribution of a key gene of the tetraether lipid biosynthetic pathway in marine Thaumarchaeota [PDF]

open access: yes, 2014
The distribution of isoprenoid glycerol dialkyl glycerol tetraethers (GDGT) lipids synthesized by Thaumarchaeota has been shown to be temperature-dependent in world oceans.

Vertical segregation and phylogenetic characterization of ammonia-oxidizing bacteria and archaea in the sediment of a freshwater aquaculture pond

open access: yesFrontiers in Microbiology, 2016
Pond aquaculture is the major freshwater aquaculture method in China. Ammonia-oxidizing communities inhabiting pond sediments play an important role in controlling culture water quality.

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]

open access: yes, 2009
A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Comparative in silico analysis of PCR primers suited for diagnostics and cloning of ammonia monooxygenase genes from ammonia-oxidizing bacteria [PDF]

open access: yes, 2008
Over recent years, several PCR primers have been described to amplify genes encoding the structural subunits of ammonia monooxygenase (AMO) from ammonia-oxidizing bacteria (AOB).

Ammonia-Oxidizer Communities in an Agricultural Soil treated with Contrasting Nitrogen Sources.

open access: yesFrontiers in Microbiology, 2013
The community of ammonia-oxidizing prokaryotes was examined in an agricultural soil treated for 6 seasons with contrasting nitrogen (N) sources. Molecular tools based on the gene encoding ammonia monooxygenase were used to characterize the ammonia ...

Predicting taxonomic and functional structure of microbial communities in acid mine drainage. [PDF]

open access: yes, 2016
Predicting the dynamics of community composition and functional attributes responding to environmental changes is an essential goal in community ecology but remains a major challenge, particularly in microbial ecology.

Biofilm Thickness Influences Biodiversity in Nitrifying MBBRs-Implications on Micropollutant Removal [PDF]

open access: yes, 2016
In biofilm systems for wastewater treatment (e.g., moving bed biofilms reactorsMBBRs) biofilm thickness is typically not under direct control. Nevertheless, biofilm thickness is likely to have a profound effect on the microbial diversity and activity ...

Community Composition and Abundance of Bacterial, Archaeal and Nitrifying Populations in Savanna Soils on Contrasting Bedrock Material in Kruger National Park, South Africa [PDF]

open access: yes, 2016
Savannas cover at least 13% of the global terrestrial surface and are often nutrient limited, especially by nitrogen. To gain a better understanding of their microbial diversity and the microbial nitrogen cycling in savanna soils, soil samples were ...
