• Nitrogen Isotopes and Mantle Geodynamics: The Emergence of Life and the Atmosphere–Crust–Mantle Connection (2013, methodology): “Among the other available analytical methods, it is worth mentioning the microbial denitrifi cation method (Sigman et al. 2001) as it allows nitrate to be accurately and rapidly converted to N2.”
• Nitrification in Marine Systems (2008, positive): “Although they have not yet been widely applied for this purpose, the recently introduced sensitive isotope methods for determination of N content of NO2 and NO3 (McIlvin and Altabet, 2005; Sigman et al., 2001) should make true tracer level incubations possible.”
• Assimilation of upwelled nitrate by small eukaryotes in the Sargasso Sea (2011, methodology): “The δ 15 N of NO 3 − was measured using the ‘denitrifier method&rsquo”
• THE MECHANISM OF ISOTOPE FRACTIONATION DURING ALGAL NITRATE ASSIMILATION AS ILLUMINATED BY THE 15N/14N OF INTRACELLULAR NITRATE 1 (2004, methodology): “For the internal pool samples, 300–500 mL per sample were filtered onto 47-mm GF/F filters and extracted with boiling water (Thoresen et al. 1982).”
• Quantification of ammonia oxidation rates and ammonia‐oxidizing archaea and bacteria at high resolution in the Gulf of California and eastern tropical North Pacific Ocean (2012, methodology): “The d15N value of N2O produced from NO { 2 + NO {3 using the ‘‘denitrifier method’’ (Sigman et al. 2001) was measured using methods described in Popp et al. (1995) and Dore et al. (1998).”
• Linking Diversity and Stable Isotope Fractionation in Ammonia-Oxidizing Bacteria (2002, methodology): “Analytical reproducibility of the denitrifier method for δ15N measurements is ±0.2‰ (Sigman et al. 2001).”
