Experimentally, researchers have attempted to model this system as a series of chemostats with climax populations of bacteria maintained at a fixed density by a continual influx of nutrients and efflux of contents (Macfarlane et al.
The authors of this book aim to establish a mathematical framework for analyzing and modeling the macro- and microscopic interactions occurring in chemostats.
5) More elaborate systems involving chemostats, flowcells, artificial mouths, and constant-depth film fermentors have been developed in an attempt to better mimic the environment of the oral cavity.
Mutations are also accumulated by using continuous cultures, preferably in chemostats under suitable selective pressure.
In the most complete study of fitness reaction norms in Zooplankton, Gliwicz (1990) used a broad array of daphniid species raised in continuous flow chemostats (Lampert 1976), which provided better control of food levels than any earlier studies.

1,2) Studies using mixed cultures grown in chemostats have shown that the increase in cariogenic organisms in biofilm does not occur due to sugar availability per si, but in response to the low pH associated to sugar catabolism.
Rotifers are the only metazoans small enough to be cultured in chemostats and, thus, they have been used successfully to test the resource competition theory (Rothhaupt 1988).
