The Simple Chemostat with Wall Growth

A model of the simple chemostat which allows for growth on the wall (or other marked surface) is presented as three nonlinear ordinary differential equations. The organisms which are attached to the wall do not wash out of the chemostat. This destroys the basic reduction of the chemostat equations to a monotone system, a technique which has been useful in the analysis of many chemostat-like equations. The adherence to and shearing from the wall eliminates the boundary equilibria. For a…

In this paper, we construct a simple chemostat-based variable yield model of competition between two bacterial strains, one of which is capable of wall growth [14]. In this model we prove the

Properties of the chemostat model with aggregated biomass and distinct dilution rates

. Understanding and exploiting the flocculation process is a major challenge in the mathematical theory of the chemostat. Here, we study a model of the chemostat involving the flocculating and

Bounded random fluctuations on the input flow in chemostat models with wall growth and non-monotonic kinetics

This paper investigates a chemostat model with wall growth and Haldane consumption kinetics. In addition, bounded random fluctuations on the input flow, which are modeled by means of the well-known

Survey on chemostat models with bounded random input flow

In this paper we study some chemostat models with random bounded fluctuations on the input flow. We start with the classical chemostat system and obtain new models incorporating, for instance, wall

Competition in a Chemostat with Wall Attachment

A mathematical model of microbial competition for limiting nutrient and wall-attachment sites in a chemostat, formulated by Freter et al, is mathematically analyzed and two bistable scenarios are of more relevance to the colonization resistance phenomena.

Microbial Competition for Nutrient and Wall Sites in Plug Flow

A surprising finding in the case of two-strain competition is the existence of a steady state solution characterized by the segregation of the two bacterial strains to separate nonoverlapping segments along the tubular reactor.

In this paper, we introduce and study a model of a Beddington–DeAngelis type food chain chemostat with periodically varying substrate. We investigate the subsystem with substrate and prey and study

Dynamics of Nonautonomous Chemostat Models

The newly developing theory ofnonautonomous dynamical systems provides the necessary concepts, in particular that of a nonautonomous pullback attractor, to analyze the dynamical behavior of nonaut autonomous chemostat models with or without wall growth, time-dependent delays, variable inputs and outputs.



Global dynamics of a mathematical model of competition in the chemostat: general response functions and differential death rates

A model of exploitative competition of n species in a chemostat for a single, essential, nonreproducing, growth-limiting resource is considered. S. B. Hsu [SIAM J. Appl. Math., 34 (1978), pp.

Competition of two microbial populations for a single resource in a chemostat when one of them exhibits wall attachment

The present article considers the case where the attached cells form no more than a monolayer, and finds that in most of the possible cases, the two competitors can coexist in a stable steady state for a wide range of the operating parameters space.
