Effects of Water Column Mixing and Stratification on Planktonic Primary Production and Dinitrogen Fixation on a Northern Red Sea Coral Reef

open access: yesFrontiers in Microbiology, 2018
The northern Red Sea experiences strong annual differences in environmental conditions due to its relative high-latitude location for coral reefs. This allows the study of regulatory effects by key environmental parameters (i.e., temperature, inorganic ...

Biological N2 Fixation in the Upwelling Region off NW Iberia: Magnitude, Relevance, and Players

open access: yesFrontiers in Marine Science, 2017
The classical paradigm about marine N2 fixation establishes that this process is mainly constrained to nitrogen-poor tropical and subtropical regions, and sustained by the colonial cyanobacterium Trichodesmium spp.

Spatial-temporal variations of N2 fixation rates and abundance of N2-fixers in the northwestern Pacific

open access: yes, 2009
To help understand characteristics of N2-fixation, N2-fixation rates, abundance and diversity of nitrogen fixers in the different water masses of the NW Pacific were examined during October 2007 and June 2008 cruises.

A Shipboard Instrument for Underway Estimates of Marine N2 Fixation [PDF]

open access: yes, 2016
Marine N2 fixation converts nitrogen gas into ammonia and accounts for the largest external nitrogen input to the oceans1. Since large portions of the global oceans are nitrogen deficient, marine N2 fixation can relieve the nitrogen limitation, thereby ...

Quantitative analysis of amino acid excretion by Methanothermobacter marburgensis under N2-fixing conditions

open access: yesScientific Reports
Methanogenic archaea (methanogens) possess fascinating metabolic characteristics, such as the ability to fix molecular nitrogen (N2). Methanogens are of biotechnological importance due to the ability to produce methane (CH4) from molecular hydrogen (H2 ...

Malonate catabolism does not drive N2 fixation in legume nodules.

open access: yes, 2016
Malonyl-coenzyme A (CoA) decarboxylase, malonyl-CoA synthetase, and malonate transporter mutants of Rhizobium leguminosarum bv. viciae and trifolii fixed N2 at wild-type rates on pea and clover, respectively.

Nitrogen Fixation by Trichodesmium and unicellular diazotrophs in the northern South China Sea and the Kuroshio in summer

open access: yesScientific Reports, 2018
Distribution of diazotrophs and their nitrogen fixation activity were investigated in the northern South China Sea (nSCS) and the Kuroshio from July 16th to September 1st, 2009. N2 fixation activities in whole seawater and
