Nitrogen isotope effects in the assimilation of inorganic nitrogenous compounds by marine diatoms
Abstract
Nitrogen isotope fractionation in the assimilation of inorganic nitrogenous compounds was studied using marine diatoms (Phaeodactylum tricornutum and Chaetoceros sp.). The isotopic composition (δ15N) of the diatoms ranged from 7 to ‐18‰ relative to that of the nitrogen source, i.e., ammonium, nitrite, or nitrate. When the growth was light‐limited, the isotope fractionation in nitrate assimilation was inversely correlated with the growth rate. The highest fractionation factor of 1.016 was obtained when the growth rate was as low as 0.025 day‐1. Fractionation was negligible when the growth, rate was higher than 1 day‐1. A steady‐state kinetic model was applied to explain the isotope fractionation in nitrate assimilation. The nitrogen isotope fractionation primarily takes place at the step of N‐O bond breaking in nitrate reduction to nitrite. The extent of the isotope fractionation associated with the nitrate uptake is very small, and barely exceeds the limit of detection.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
