Blooms of Baltic Sea Aphanizomenon sp. (Cyanobacteria) collapse after internal phosphorus depletion (2007, background): “However, assuming that all Mo is used in nitrogenase with a Fe:Mo ratio of 19:1 to 25:1 (Tuit et al. 2004), 41 to 54% of the total Fe content in Aphanizomenon is in nitrogenase when the heterocyst frequency and Mo content is maximal in early June.”
Nitrogen‐fixation strategies and Fe requirements in cyanobacteria (2007, background): “…calculated that an average internal concentration of 19–1,000 mmol L21 Fe in Croccosphaera at abundances of 106 cells L21 would require only 2.4 pmol L21 Fe compared with 0.1 nmol L21 available in seawater, indicating that Fe limitation in this organism in the ocean was unlikely (Tuit et al. 2004).”
Differing responses of marine N2 fixers to warming and consequences for future diazotroph community structure (2014, methodology): “Samples for cell counts and chl a were always taken at the same time in the diel cycle (Tuit et al. 2004), between 09:00 and 10:00 h in the morning.”
Interactions between changing pCO2, N2 fixation, and Fe limitation in the marine unicellular cyanobacterium Crocosphaera (2008, methodology): “Samples from each culture bottle were always taken at the same time in the diel cycle (Tuit et al. 2004), between 09:00 h and 10:00 h in the morning, to measure cell density and, thus, to determine changes in growth rate.”
Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean (2007, background): “…reported that laboratory measurements of cultured unicellular diazotrophs (2 3 107 cells ml21) had a daily N2 fixation rate of 15 fmol cell21, and Tuit et al. (2004) reported a range for Crocosphaera in culture of 3.2–14.2 fmol cell21, with the lower measurements attributed to low Fe conditions.”
