Principles of the light-limited chemostat: theory and ecological applications

, 2002
Light is the energy source that drives nearly all ecosystems on planet Earth. Yet, light limitation is still poorly understood. In this paper, we present an overview of the principles of the light-limited chemostat.

Breakdown time of a chemostat exposed to stochastic noise

, 2005
The stochastic dynamics of a chemostat with three trophic levels, substrate-bacterium-worm, is analyzed. It is assumed that the worm population is perturbed by environmental stochastic noise causing extinction in finite time.

Sustainable Water Treatment Through Fractional-Order Chemostat Modeling with Sliding Memory and Periodic Boundary Conditions: A Mathematical Framework for Clean Water and Sanitation

Fractal and Fractional
This work develops and analyzes a novel fractional-order chemostat system (FOCS) with a Caputo fractional derivative (CFD) featuring a sliding memory window and periodic boundary conditions (PBCs), designed to model microbial pollutant degradation in ...

High-pressure continuous culturing: life at the extreme

Applied and Environmental Microbiology
Microorganisms adapted to high hydrostatic pressures at depth in the oceans and within the subsurface of Earth’s crust represent a phylogenetically diverse community thriving under extreme pressure, temperature, and nutrient availability conditions.

Circadian rhythmicity during prolonged chemostat cultivation of Neurospora crassa

, 2007
Following exposure to light and attainment of steady-state in the chemostat, Neurospora was grown in constant conditions of darkness at 25 °C for 6 days.

Comparative analysis of two chemostat models including substrate and biomass inhibitions

Biomath
We consider the acetogenesis and hydrogenotrophic methanogenesis phases of the anaerobic digestion model and we include the inhibition of methanogenics, first by volatile fatty acids (VFAs) then by acetogenics. We investigate mathematically the dynamics

Annotated chemostat model.

Chemostat model describing the change in concentrations of gelatin substrate (S), degradation product of the substrate (P), protease enzyme produced by the cooperator (E), the enzyme-producing bacterial cooperator (X1), and the bacterial cheater which ...

How Can Viruses Affect the Growth of Zooplankton on Phytoplankton in a Chemostat?

Mathematics
In this work, we investigated a simple mathematical model describing the consumption of virus-infected phytoplankton by zooplankton in a chemostat. The system was studied by calculating the basic reproduction number, the equilibrium points, and their ...

Three Species Food Web in a Chemostat

, 2020
: In this paper, we consider a model describing predator prey interaction in a chemostat that incorporates general response functions and identical removal rates.
