Methods designed to detect microorganisms involved in the biogeochemistry of nitrogen in the marine environment are rapidly being developed and deployed in ecological investigations. Probes based on phylogenetic sequences (usually rRNA) and those based on the sequences of functional genes or proteins have both been demonstrated in the nitrogen cycle. The most progress has been made for ammonia oxidizers; several sets of PCR primers have been described and their specificity may be optimized to…

Cultivation-based and molecular approaches to characterisation of terrestrial and aquatic nitrifiers
TLDR
There is increasing evidence for physiological properties driving the environmental distribution of particular groups of ammonia oxidisers and for associations between nitrification process rates and ammonia oxidiser community structure.
Nitrogen cycle of the open ocean: from genes to ecosystems.
TLDR
The nitrogen cycle in the oceans is an integral feature of the function of ocean ecosystems and will be a central player in how oceans respond during global environmental change.
Molecular analysis of the nitrogen cycle in deep-sea microorganisms from the Nankai Trough: genes for nitrification and denitrification from deep-sea environmental DNA
TLDR
It is suggested that nitrifiers and denitrifiers live in the same area of the Nankai Trough and the nitrogen cycle exists even in the deep-sea.
In situ reverse transcription-PCR and detection of nirS genes by Fluorescent In Situ Hybridization ( FISH ) to study denitrifying bacteria
TLDR
An approach to study the expression of nirS genes in denitrifying bacteria by selective detection of cells actively expressing functional genes within a community using In Situ Reverse Transcription-PCR (ISRT-PCC) could become a powerful culture-independent technique in microbial ecology.
Geomicrobiology of nitrogen in a coastal aquifer : isotopic and molecular methods to examine nitrification and denitrification in groundwater
Abstract : The flux excess nitrogen is deleterious to coastal waters, resulting in deterioration of the water quality, increases in harmful algal blooms and disease in commercial fish stocks. On Cape…
Molecular Tools for Studying Biogeochemical Cycling in Salt Marshes
TLDR
It is hoped the data obtained from molecular studies in marsh habitats in the future will lead to a better understanding of the linkages between the structure and the function of the microbial communities that mediate biogeochemical cycling in the environment.
The effect of macrofaunal functional diversity on density and diversity of nitrifying and denitrifying organisms
Nitrification, the oxidation of ammonia to nitrate via nitrite, is central to the cycling of nitrogen in the environment and, when coupled with denitrification, alleviates the effects of…
The response of nitrogen cycling and bacterial communities to E. coli invasion in aquatic environments with submerged vegetation.
Nitrate uptake by heterotrophic bacteria and the diversity of bacterial nitrate assimilation genes in marine systems
TLDR
The finding that NO3 availability and patterns of NO3 utilization are positively correlated with nasA community structure variability and the abundance of particular groups of nasA genes, indicates that patterns of No3 supply, in the marine environment, are sufficiently important to be a factor in regulating bacterial communities.
Denitrification and Anaerobic Ammonium Oxidization Across the Sediment–Water Interface in the Hypereutrophic Ecosystem, Jinpu Bay, in the Northeastern Coast of China
Denitrification and anaerobic ammonium oxidization (anammox) are considered the most important processes of removing reactive nitrogen from natural aquatic environments. We measured and compared in…

Functional and Taxonomic Probes for Bacteria in the Nitrogen Cycle
TLDR
Although quantification is still rudimentary, comparison among immunofluorescence enumeration, PCR amplification and quantitative hybridization allow an assessment of genotype vs phenotype abundances.
Numbers, activities, and diversity of autotrophic ammonia-oxidizing bacteria in a freshwater, eutrophic lake sediment
TLDR
Pure-culture isolations from a positive MPN tube inoculated with oxygenated sediment and representing a single point in a seasonal cycle produced ammonia-oxidizing strains belonging to the genus Nitrosospira, which extend the serological diversity of this group of bacteria.
Molecular analysis of enrichment cultures of marine ammonia oxidisers.
TLDR
The approach enabled analysis of ammonia oxidiser enrichments at an early stage and without the requirement for isolation of pure cultures, significantly reducing the time required and facilitating quantitative assessment of relatedness of strains.

Marine ammonia- and nitrite-oxidizing bacteria: serological diversity determined by immunofluorescence in culture and in the environment.
TLDR
Ammonium- and nitrite-oxidizing bacteria were enumerated in samples taken in a depth profile in the Southern California Bight by immunofluorescence assays for two ammonium oxidizers and two nitrite oxidizers.

Evolutionary relationships among ammonia- and nitrite-oxidizing bacteria
TLDR
The nitrifiers, as a group, apparently are not derived from an ancestral nitrifying phenotype, and consideration of physiology and phylogenetic distribution suggested that nitrite-oxidizing bacteria of the alpha and gamma subdivisions are derived from immediate photosynthetic ancestry.
