A simple model has been formulated to simulate diauxic growth of denitrifying bacteria. It is capable of fitting the experimental results of batch growth experiments with Pseudomonas denitrificans under various conditions. It successfully predicts the observed lags when a pure culture of this bacterium switches from oxygen to nitrate as terminal electron acceptor. The model includes the effect of carbon substrate limitation and length of aerobic phase and does not run into problems when switching from anoxic to aerobic conditions, unlike prior models of diauxic growth.
已建立一个简单模型来模拟反硝化细菌的二次生长。它能够拟合在各种条件下以反硝化假单胞菌进行的分批生长实验的实验结果。当这种细菌的纯培养物从氧气作为末端电子受体切换到硝酸盐时,它成功地预测了观察到的延迟期。该模型包括碳底物限制和需氧阶段长度的影响,并且与先前的二次生长模型不同,在从缺氧条件切换到需氧条件时不会出现问题。
