| Abstract | In practical situations where direct observation of the morphology and biomass distribution of filamentous microorganisms is not feasible, there is at present some uncer- tainty concerning the appropriate mathematical model to use to describe the substrate uptake and growth kinetics of these organisms. Some authors have argued that a "cubic" model was superior to available alternatives. In the present article, the experimental evi- dence upon which this claim was based is reanalyzed in detail. We identify a conceptual flaw in the rationale that led originally to that conclusion; we show that equally good fits to experimental data are obtained with the classical exponential model as with the cubic model. Finally, we demonstrate that a Monod-based nutrient uptake model outperforms both the cubic and the exponential models, and allows the full data set to be fitted, includ- ing a transition phase during which the rate of oxygen uptake decreases. Consequences of these observations, and the simplifications they afford, for the modeling of environ- mental or engineered systems are briefly addressed. |
