| Description
| - V článku je popsán model růstu bakteriální populace na směsi dvou cukrů. Tento model předpokládá, že bakterie jsou evolučně adaptovány tak, že vždy využívají ten zdroj energie, který maximalizuje jejich okamžitou růstovou rychlost. Uvedený model umožňuje predikovat okamžik, kdy by mělo dojít k přepnutí z jednoho zdroje energie na druhý. Tato predikce je pak konfrontována s experimentálními daty. Ukazuje se, že shoda je statisticky významná. Model dále studuje vliv optimálního přepínání mezi jednotlivými energetickými zdroji i pro případ bakteriálního růstu v chemostatu. (cs)
- A population dynamical model describing growth of bacteria on two substrates is analyzed. The model assumes that bacteria choose substrates in order to maximize their per capita population growth rate. For batch bacterial growth, the model predicts that as the concentration of the preferred substrate decreases there will be a time at which both substrates provide bacteria with the same fitness and both substrates will be used simultaneously thereafter. Preferences for either substrate are computed as a function of substrate concentrations. The predicted time of switching is calculated for some experimental data given in the literature and it is shown that the fit between predicted and observed values is good. For bacterial growth in the chemostat, the model predicts that at low dilution rates bacteria should feed on both substrates while at higher dilution rates bacteria should feed on the preferred substrate only.
