Model of bacterial growth influenced by substrate C:N ratio and concentration

Abstract

The present study describes and explores a model to determine bacterial growth, respiration and net ammonium remineralization as a function of the average substrate C:N ratios and concentrations of organic substrates.Several experimental data sets were used to estimate critical parameters of the model.These data sets suggest that carbon and nitrogen growth efficiencies play a central role in the computation of bacterial growth, respiration, and net ammonium remineralization.The new parameterization of these processes, which takes into account the variability of carbon and nitrogen growth efficiencies with the C:N ratio of organic substrates, agrees with the observed expermental trends.The structure of the model and the results are compared to those of other models.According to the output of our model and to experimental data, which were used to validate parts of the structure, bacterial growth increases with organic substrate concentration and decreasing C:N ratios.As a consequence, a low carbon content relative to nitrogen in the substrates does not limit bacterial growth.

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.
