摘要

Microbial populations have obvious advantages as an object of populational analysis, at least in several aspects. First, they exhibit a unique ability for rapid reproduction and, therefore, have very short life spans of generations. Intensive culturing of microorganisms during one or two days may yield as many as 100 sequential generations. Second, microorganisms can be easily grown under specified and controllable experimental conditions in sufficiently simple media, which is very important for good reproducibility of results. The third advantage consists in a large size of microbial populations, which makes it possible to use the well-developed apparatus of the theory of differential equations for mathematical description of processes of population development. All these advantages are actualized in the processes of long-term continuous cultivation of microorganisms, the two major types of which, chemostat and turbidostat, are known since 1950s .
