Ecological Modelling, 1988
Abstract A general model for the interaction of two bacterial populations with interfering metabolic activities is provided. We discuss the dynamics of the system. As a result we obtain bistability under continuous-flow conditions if the growth rate of the first organism in the food chain depends on the substrate of the second, and if the growth rate

Journal of Physics E: Scientific Instruments, 1972
Modifications of a commercially available fermentor which permit an economical conversion of a simple batch fermentor to a small, open-type, single-phase continuous culture apparatus are described. The device may be employed in basic research and classroom demonstrations of experiments designed to illustrate the principles of continuous culture of ...

A chemostat study of ethanol inhibition
Biotechnology and Bioengineering, 1971AbstractThe mode of ethanol action on both the steady‐state and the dynamic properties of K. aerogenes was investigated using a nitrogen‐limited chemostat. Reduction in the maximum growth rate (μm) suggests that noncompetitive enzyme inhibition could occur, but Lineweaver–Burk analysis showed the inhibition to be more complex. A consistent mechanism of

Food chain dynamics in the chemostat
Mathematical Biosciences, 1998The asymptotic behavior of a tri-trophic food chain model in the chemostat is studied. The Monod-Herbert growth model is used for all trophic levels. The analysis is carried out numerically, by finding both local and global bifurcations of equilibria and of limit cycles with respect to two chemostat control parameters: the dilution rate of the ...

This chapter is devoted to the stabilization of chemostats under measurement delays. Continuous stirred microbial bioreactors, often called chemostats, cover a wide range of applications; specialized “pure culture” biotechnological processes for the production of specialty chemicals (proteins, antibiotics, etc.) as well as large-scale environmental ...

Competitive Coexistence in an Oscillating Chemostat
SIAM Journal on Applied Mathematics, 1981An ordinary differential equation model of two species competing for a single essential nutrient in a periodic environment is studied. Coexistence of the two species is demonstrated when the amplitude of the forcing is not too small nor too large. The results explain some of the results obtained from numerical simulation of chemostat experiments [9].

Aus den Gleichungen fur einen einfachen Chemostaten folgt, das die maximal verwendbare Verdunnungsrate auf einen Wert beschrankt ist, der geringfugig unter der maximalen spezifischen Wachstumsrate µm liegen mus. Dieser Wert wird als kritische Verdunnungsrate, Dc, bezeichnet.

Critical Consideration of Chemostat Experiments
1993The use of chemostats in rotifer culture was first proposed by Droop (in Conover 1970) who regarded this technique as a promising approach for eco-physiological studies. He referred to, and later described in more detail (Droop 1976), a two-stage system in which the second-stage rotifer chemostat is supplied by a steady-state algal culture.

For a biologist, chemostat is a replica of a simple lake. Thus, chemostat models are widely used to represent the growth of species in a lake where the organisms such as algae feed on growth-limiting nutrients such as nitrogen and phosphorus. The analogy between a simple lake and a chemostat becomes clear from the Table 2.1.
