Random Chemostats with Competition and Different Kinetics to Investigate the Growth of the Gut Microbiome

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We investigate some chemostat models incorporating wall growth, competition, random fluctuations on the dilution rate, and different consumption functions (Monod and Haldane). We analyze the asymptotic behavior of the solutions of the corresponding random differential systems to establish conditions on the model parameters under which the ...

Robust control for an uncertain chemostat model [PDF]

open access: yes, 2004
In this paper we consider a control problem for an uncertain chemostat model with a general monotone growth function. This uncertainty affects the model (growth function) as well as the outputs (measurements of substrate).

Genetically Programmed Control of Overflow Metabolism

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 6, Page 1624-1633, June 2026.
ABSTRACT Overflow metabolism is a highly undesirable phenomenon that occurs in virtually all cell factories. Although several schemes have been applied to avoid overflow metabolism, this problem remains far from being solved. In this study, a genetic sensor for detecting overflow metabolism was designed, and its substrate specificity and reversibility ...

Establishment of a Single‐Cell Minimal Medium: A Case Study for Microfluidic Cultivation of Corynebacterium glutamicum

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 6, Page 1648-1660, June 2026.
Conventional bulk media are often unsuitable for single‐cell cultivation and analysis because they provide excess nutrients or lack essential components. Redesigning the medium allows for controlled, defined growth, enabling the development of a robust minimal medium that supports quantitative and reproducible single‐cell analysis across different ...

Comparison of numerical simulations of reactive transport and chemostat-like models [PDF]

open access: yesComputational Ecology and Software, 2011
The objective of the paper is to evaluate the ability of reactive transport models and their numerical implementations (such as MIN3P) to simulate simple microbial transformations in conditions of chemostat or gradostat models, that are popular in ...

Basic regulatory principles of Escherichia coli's electron transport chain for varying oxygen conditions.

open access: yesPLoS ONE, 2014
For adaptation between anaerobic, micro-aerobic and aerobic conditions Escherichia coli's metabolism and in particular its electron transport chain (ETC) is highly regulated.

Modeling and analysis of random and stochastic input flows in the chemostat model

open access: yesDiscrete & Continuous Dynamical Systems - B, 2019
In this paper we study a new way to model noisy input flows in the chemostat model, based on the Ornstein-Uhlenbeck process. We introduce a parameter β as drift in the Langevin equation, that allows to bridge a gap between a pure Wiener process, which is

Historical Contingency Drives Freshwater Microbial Community Assembly Across Successional Time

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using a 60‐day full‐factorial reciprocal transplant microcosm experiment, we quantified the relative contributions of historical contingency, environmental selection, and dispersal limitation to freshwater bacterial community assembly. We show a pronounced temporal shift from early dispersal‐driven assembly to late‐stage dominance of historical ...

Dynamics of an Impulsive Stochastic Nonautonomous Chemostat Model with Two Different Growth Rates in a Polluted Environment

open access: yesDiscrete Dynamics in Nature and Society, 2019

Microbial interactions as modular: Implications for ecosystem dynamics and evolution

open access: yesEcological Monographs, Volume 96, Issue 2, May 2026.
Abstract Microbial communities contribute to numerous processes that profoundly impact planetary and human health. They therefore hold potential for addressing many of today's pressing global challenges. Microbial ecosystems have been studied at many levels, ranging from the molecular processes of individual cells to the emergent properties and ...
