The microbial nitrogen-cycling network

MMM Kuypers, HK Marchant, B Kartal - Nature Reviews Microbiology, 2018 - nature.com
Nitrogen is an essential component of all living organisms and the main nutrient limiting life
on our planet. By far, the largest inventory of freely accessible nitrogen is atmospheric
dinitrogen, but most organisms rely on more bioavailable forms of nitrogen, such as …

How to make a living from anaerobic ammonium oxidation

B Kartal, NM de Almeida, WJ Maalcke… - FEMS microbiology …, 2013 - academic.oup.com
Anaerobic ammonium-oxidizing (anammox) bacteria primarily grow by the oxidation of
ammonium coupled to nitrite reduction, using CO2 as the sole carbon source. Although they
were neglected for a long time, anammox bacteria are encountered in an enormous species …

Microbial regulation of terrestrial nitrous oxide formation: understanding the biological pathways for prediction of emission rates

HW Hu, D Chen, JZ He - FEMS microbiology reviews, 2015 - academic.oup.com
The continuous increase of the greenhouse gas nitrous oxide (N2O) in the atmosphere due
to increasing anthropogenic nitrogen input in agriculture has become a global concern. In
recent years, identification of the microbial assemblages responsible for soil N2O production …

[HTML][HTML] Nitric oxide and nitrous oxide turnover in natural and engineered microbial communities: biological pathways, chemical reactions, and novel technologies

F Schreiber, P Wunderlin, KM Udert… - Frontiers in …, 2012 - frontiersin.org
Nitrous oxide (N2O) is an environmentally important atmospheric trace gas because it is an
effective greenhouse gas and it leads to ozone depletion through photo-chemical nitric
oxide (NO) production in the stratosphere. Mitigating its steady increase in atmospheric …

Hydrazine synthase, a unique phylomarker with which to study the presence and biodiversity of anammox bacteria

HR Harhangi, M Le Roy, T van Alen, B Hu… - Applied and …, 2012 - Am Soc Microbiol
Anaerobic ammonium-oxidizing (anammox) bacteria play an important role in the
biogeochemical cycling of nitrogen. They derive their energy for growth from the conversion
of ammonium and nitrite into dinitrogen gas in the complete absence of oxygen. Several …

[HTML][HTML] Diversity and evolution of bioenergetic systems involved in microbial nitrogen compound transformations

J Simon, MG Klotz - Biochimica et Biophysica Acta (BBA)-Bioenergetics, 2013 - Elsevier
Nitrogen is an essential element of life that needs to be assimilated in its most reduced form,
ammonium. On the other hand, nitrogen exists in a multitude of oxidation states and,
consequently, nitrogen compounds (NCs) serve as electron donor and/or acceptors in many …

New pathways and processes in the global nitrogen cycle

B Thamdrup - Annual Review of Ecology, Evolution, and …, 2012 - annualreviews.org
Our understanding of the players and pathways of the global nitrogen cycle has advanced
substantially over recent years with discoveries of several new groups of organisms and
new types of metabolism. This review focuses on recently discovered processes that add …

The metagenome of the marine anammox bacterium 'Candidatus Scalindua profunda' illustrates the versatility of this globally important nitrogen cycle bacterium

J van de Vossenberg, D Woebken… - Environmental …, 2013 - Wiley Online Library
Anaerobic ammonium‐oxidizing (anammox) bacteria are responsible for a significant
portion of the loss of fixed nitrogen from the oceans, making them important players in the
global nitrogen cycle. To date, marine anammox bacteria found in marine water columns …

[HTML][HTML] The nitrogen cycle

LY Stein, MG Klotz - Current Biology, 2016 - Elsevier
Nitrogen is the fourth most abundant element in cellular biomass, and it comprises the
majority of Earth's atmosphere. The interchange between inert dinitrogen gas (N 2) in the
extant atmosphere and 'reactive nitrogen'(those nitrogen compounds that support, or are …

Role of extracellular polymeric substance in determining the high aggregation ability of anammox sludge

X Hou, S Liu, Z Zhang - Water research, 2015 - Elsevier
The high aggregation ability of anammox sludge has been extensively observed, but the
cause for their aggregation is challenging. Here the structure and composition of
extracellular polymeric substance (EPS) excreted from anammox sludge were systematically …
