Atmospheric concentrations of the powerful greenhouse gas nitrous oxide (N 2 O) have
increased dramatically over the last 100 years, and part of these emissions come from …

Globally, denitrification is commonly employed in biological nitrogen removal processes to
enhance water quality. However, substantial knowledge gaps remain concerning the overall …

Life evolved and flourished in the absence of molecular oxygen (02). As the 02 content of
the atmosphere rose to the present level of 21% beginning about two billion years ago …

The nitrogen (N) cycle is composed of multiple transformations of nitrogenous compounds,
catalyzed primarily by microbes. The N cycle controls the availability of nitrogenous nutrients …

Rates of nitrate (NO 3-) reduction to nitrogen gas (N 2) and ammonium (NH 4+) were
measured in August and December 1999 on intact cores (Laguna Madre and Baffin Bay …

Dissimilatory nitrate reduction to ammonium (DNRA), an important intermediate process in
the N-cycle, links N-compound oxidation and reduction processes. Hence, the oxic-anoxic …

Two PCR primer sets were developed for the detection and quantification of cytochrome cd
1-denitrifying bacteria in environmental marine samples. The specificity and sensitivity of …

Dissimilatory nitrate reduction processes, including denitrification, anaerobic ammonium
oxidation (ANAMMOX), and dissimilatory nitrate reduction to ammonium (DNRA), play an …

Benthic respiration, sediment–water nutrient fluxes, denitrification and dissimilatory nitrate
reduction to ammonium (DNRA) were measured in the upper section of the Parker River …

The main pathways of sulfide oxidation in marine sediments involve complex interactions of
chemical reaction and microbial metabolism. Sulfide becomes partly oxidized and bound by …
