Iron requirements for dinitrogen‐ and ammonium‐supported growth in cultures of Trichodesmium (IMS 101): Comparison with nitrogen fixation rates and iron: carbon ratios of field populations (2003, methodology): “The Fe burden structurally associated with the nitrogenase enzyme complex under N2supported growth in Trichodesmium has recently been estimated from a molecular iron use model (Kustka et al. 2003).”
Latitudinal distribution of Trichodesmium spp. and N 2 fixation in the Atlantic Ocean (2010, methodology): “The method of collecting Trichodesmium filaments (i.e. filtering 50 to 130L of seawater from the underway seawater supply through a 40um mesh) seems a little odd.”
Evidence of active dinitrogen fixation in surface waters of the eastern tropical South Pacific during El Niño and La Niña events and evaluation of its potential nutrient controls (2013, background): “Due to the high Fe requirements for nitrogenase [Berman-Frank et al., 2001; Kustka et al., 2003a, 2003b], it is also suspected to control N2 fixation [Paerl et al., 1994; Mills et al., 2004; Saito et al., 2011], but this process and its controlling factors have been very poorly studied in this area.”
Environmental controls on coccolithophore calcification (2012, background): “The nitrogen source for growth alters the Fe requirement: diazotrophy needs more Fe per unit nitrogen assimilation rate than NO3– or, particularly, NH4+ assimilation (Kustka et al. 2003).”
Uptake of molybdenum and vanadium by a nitrogen-fixing soil bacterium using siderophores (2008, background): “Therefore, the availability of these trace metals may control the Earth’s nitrogen cycl”
Interconnection of nitrogen fixers and iron in the Pacific Ocean: Theory and numerical simulations (2012, background): “As diazotrophs also have a higher requirement for iron (required for nitrogenase [Kustka et al., 2003]), we assume that RD > RP.”
Biomass and primary productivity of the cyanobacterium Trichodesmium spp. in the tropical N Atlantic ocean (2004, background): “This input may provide a source of iron for diazotrophs such as Trichodesmium (Berman-Frank et al., 2001; Kustka et al., 2003).”
Nitrogen fixation by Trichodesmium spp.: An important source of new nitrogen to the tropical and subtropical North Atlantic Ocean (2005, background): “The recognition that photosynthetic diazotrophs have a higher cell quota for iron [Berman-Frank et al., 2001; Kustka et al., 2003] has led to the general hypothesis that iron enrichment resulting from dust deposition in the tropical North Atlantic is responsible for enhanced levels of diazotrophy…”
Iron availability limits the ocean nitrogen inventory stabilizing feedbacks between marine denitrification and nitrogen fixation (2007, background): “0886-6236/07/2006GB002762 GB2001 1 of 12 field data [Wu et al., 2003], laboratory studies in conjunction with satellite data [Berman-Frank et al., 2001], and laboratory studies in conjunction with field observations [Kustka et al., 2003b].”
Nitrogen‐fixation strategies and Fe requirements in cyanobacteria (2007, background): “Higher intracellular iron quotas were calculated and found in diazotrophic cyanobacteria in comparison with nondiazotrophic phytoplankton (Kustka et al. 2003; Tuit et al. 2004).”
