Freshwater Ammonia-Oxidizing Archaea Retain amoA mRNA and 16S rRNA during Ammonia Starvation
In their natural habitats, microorganisms are often exposed to periods of starvation if their substrates for energy generation or other nutrients are limiting.

Increased salinity improves the thermotolerance of mesophilic nitrification [PDF]
Nitrification is a well-studied and established process to treat ammonia in wastewater. Although thermophilic nitrification could avoid cooling costs for the treatment of warm wastewaters, applications above 40 A degrees C remain a significant challenge.

Serological studies on lithotrophic, ammonia oxidizing bacteria
Rabbit antisera were prepared against living cells of six different ammonia oxidizing nitrifying bacteria. They were examined as to cross-reactivity in the agglutination test (Microtiter-system) with 24 nitrifier strains, including members of all known genera.

Relating Anaerobic Digestion Microbial Community and Process Function [PDF]
Anaerobic digestion (AD) involves a consortium of microorganisms that convert substrates into biogas containing methane for renewable energy. The technology has suffered from the perception of being periodically unstable due to limited understanding of ...

Correlating microbial community profiles with geochemical data in highly stratified sediments from the Arctic Mid-Ocean Ridge [PDF]
Microbial communities and their associated metabolic activity in marine sediments have a profound impact on global biogeochemical cycles. Their composition and structure are attributed to geochemical and physical factors, but finding direct correlations ...

Ammonia-oxidizing bacteria respond to multifactorial global change [PDF]
Recent studies have demonstrated that multiple co-occurring global changes can alter the abundance, diversity, and productivity of plant communities. Belowground processes, often mediated by soil microorganisms, are central to the response of these communities to global change.
