Dictyostelium discoideum and Escherichia coli were aerobically propagated in mixed continuous culture in a predator-prey relationship, and the effects of temperature and holding times were examined. Oscillations developed in the concentration of glucose, the limiting substrate for E. coli, and in the densities of the two populations, but eventually steady-state populations were reached. The experimental data were analyzed according to the Lotka-Volterra model for prey-predator relationships and by the Monod model for saturation kinetics. A comparison of the adequacy of the two models in describing predation is given.
盘基网柄菌和大肠杆菌在捕食者 - 猎物关系的混合连续培养中进行好氧繁殖,并研究了温度和保留时间的影响。大肠杆菌的限制性底物葡萄糖浓度以及两个种群的密度出现了振荡,但最终达到了稳态种群。根据捕食者 - 猎物关系的洛特卡 - 沃尔泰拉模型和饱和动力学的莫诺德模型对实验数据进行了分析。给出了两种模型在描述捕食方面的充分性比较。
