ABSTRACT Denitrification and nitrate ammonification are considered the highest-energy-yielding respiration systems in anoxic environments after oxygen has been consumed. The corresponding free energy changes are 7 and 35% lower than that of aerobic respiration, respectively. Growth yield determinations with pure cultures of Paracoccus denitrificans and Pseudomonas stutzeri revealed that far less energy is converted via ATP into cell mass than expected from the above calculations… 

Fermentative Bacteria Influence the Competition between Denitrifiers and DNRA Bacteria

Results of this study clearly show that not only the ratio of available substrates, but also the nature of the electron donor influences the outcome of competition between DNRA and denitrification.

Transcriptional and metabolic regulation of denitrification in Paracoccus denitrificans allows low but significant activity of nitrous oxide reductase under oxic conditions.

The demonstrated reduction of N2O at high O2 partial pressure and low N2 O concentrations by a bacterium not known as a typical aerobic denitrifier may provide one clue to the understanding of why some soils appear to act as sinks rather than sources for atmospheric N 2 O.

How to make a living from anaerobic ammonium oxidation.

An analysis of the metabolic opportunities of anammox bacteria suggests alternative chemolithotrophic lifestyles that are independent of these compounds, and current concepts are still largely hypothetical and put forward the most intriguing questions that need experimental answers.

Anaerobic phototrophic nitrite oxidation by Thiocapsa sp. strain KS 1 and Rhodopseudomonas

The ability to use nitrite phototrophically as electron donor is widespread in nature, but low MPN counts indicate that its contribution to nitrite oxidation in the studied habitats is rather limited.

Transcriptional and environmental control of bacterial denitrification and N2O emissions

This minireview describes the current picture for transcriptional regulation of denitrification in the model bacterium, Paracoccus Denitrificans, highlighting differences in other denitrifying bacteria where appropriate, as well as gaps in understanding and speculating how this information can be translated into development of novel greenhouse gas mitigation strategies.

Dissimilatory Nitrate Reduction to Ammonium and Responsible Microbes in Japanese Rice Paddy Soil

Dissimilatory nitrate reduction to ammonium (DNRA), which competes with denitrification for nitrate, is investigated in order to challenge the conventional view of nitrogen cycling in paddy soils and indicates that DNRA reduces N loss through Denitrification and nitrate leaching and provides ammonium to rice roots in rice paddy fields.

Denitrification versus respiratory ammonification: environmental controls of two competing dissimilatory NO3−/NO2− reduction pathways in Shewanella loihica strain PV-4

Recent findings suggest that organisms with both the denitrification and respiratory ammonification pathways are not uncommon in soil and sediment ecosystems, and strain PV-4 offers a tractable experimental system to explore regulation of dissimilatory NO3−/NO2− reduction pathways.

Nitrate Reducing and Denitrifying Bacteria in Oil / Brine Contaminated Soils

Soil microorganisms are a fundamental part of biogeochemical cycling of nitrogen. Denitrification is an important component of nitrogen cycling, in which some microorganisms (e.g. denitrifying



Energy yield of denitrification: an estimate from growth yield in continuous cultures of Pseudomonas denitrificans under nitrate-, nitrite- and oxide-limited conditions.

The molar growth yields of Pseudomonas denitrificans, for nitrate, nitrite and nitrous oxide, were determined in chemostat culture under electron acceptor-limited conditions and oxidative phosphorylation occurs to a similar extent in each of the electron transport chains associated with the reduction.

Emerging principles of inorganic nitrogen metabolism in Paracoccus denitrificans and related bacteria

Evidence is given which shows that the physiological differences between P. denitrificans and Thiosphaera pantotropha are less fundamental than previously thought and should be able to grow chemolithotrophically with hydroxylamine.

Denitrification is intimately related to fundamental cellular processes that include primary and secondary transport, protein translocation, cytochrome c biogenesis, anaerobic gene regulation, metalloprotein assembly, and the biosynthesis of the cofactors molybdopterin and heme D1.

Anaerobic degradation of acetone and higher ketones via carboxylation by newly isolated denitrifying bacteria.

Five strains of Gram-negative denitrifying bacteria that used various ketones as sole carbon and energy sources were isolated from activated sludge from a municipal sewage plant, providing evidence that acetone is channelled into the intermediary metabolism of this strain via carboxylation to acetoacetate.

Nitrogen, Carbon, and Sulfur Metabolism in NaturalThioploca Samples

The results suggest that Thioploca species are facultative chemolithoautotrophs capable of mixotrophic growth.

Denitrification: ecological niches, competition and survival

It is suggested that organic carbon is more important than oxygen status in determining denitrifying enzyme content of habitats, and Michaelis-Menten theoretical models suggest the conditions required to achieve changes in partitioning between the two fates of nitrate.

Chemolithotrophic growth ofDesulfovibrio desulfuricans with hydrogen coupled to ammonification of nitrate or nitrite

AbstractTwo of nine sulfate reducing bacteria tested,Desulfobulbus propionicus andDesulfovibrio desulfuricans (strain Essex 6), were able to grow with nitrate as terminal electron acceptor, which was

This review focuses on recent progress that has been made in understanding the enzymology and bioenergetics of respiratory nitrite ammonification and the proteins predicted by these genes are unrelated in the two bacteria but similar to proteins of the respective conventional cytochrome c biogenesis systems.
