Modeling the growth of Pseudomonas putida using the Bertalanffy-Pütter model .

[摘要] Anadurai et al. (2000) fitted the models of Verhulst (logistic growth), Gompertz and Richards to givengrowth data of Pseudomonas putida. From the three models tested, the logistic model fitted best. Each of theforementioned models corresponds to a specific exponent-pair of the five parameter Bertalanffy- PütterBP(a, b) model class. We found that the sum of squared errors (SSE) of the model BP(2.81, 3.32)improved the SSE of the logistic model BP(1, 2) by the factor of five. Furthermore, assuming a constantbiomass-substrat-yield, the best-fit BP model had a slightly better fit than the classical Monod model.
