Quantitative physiology and biomass composition of Cyberlindnera jadinii in ethanol-grown cultures

Biotechnology for Biofuels and Bioproducts
Background Elimination of greenhouse gas emissions in industrial biotechnology requires replacement of carbohydrates by alternative carbon substrates, produced from CO2 and waste streams.

Nonlinear Modelling and Qualitative Analysis of a Real Chemostat with Pulse Feeding

Discrete Dynamics in Nature and Society, 2010
The control of substrate concentration in the bioreactor medium should be due to the substrate inhibition phenomenon. Moreover, the oxygen demand in a bioreactor should be lower than the dissolved oxygen content.

Dynamical analysis of multi-nutrient and single microorganism chemostat model in a polluted environment

, 2018
In this paper, we propose a multi-nutrient and single microorganism chemostat model with stochastic effect and impulsive toxicant input. Firstly, for the system neglecting stochastic effect, we investigate the global dynamics including the existence and ...

Extension du modèle du chemostat avec floculation

, 2012
[Departement_IRSTEA]Ecotechnologies [TR1_IRSTEA]INSPIREInternational audienceWe discuss a model of the chemostat where the species are present in two forms, isolated bacteria and under an aggregated form like attached bacteria or bacteria in flocks ...

Bifurcation Analysis of a Chemostat Model of Plasmid-Bearing and Plasmid-Free Competition with Pulsed Input

Journal of Applied Mathematics, 2014
A chemostat model of plasmid-bearing and plasmid-free competition with pulsed input is proposed. The invasion threshold of the plasmid-bearing and plasmid-free organisms is obtained according to the stability of the boundary periodic solution.

Properties of the chemostat model with aggregated biomass

, 2018
We revisit the well-known chemostat model, considering that bacteria can be attached together in aggregates or flocs. We distinguish explicitly free and attached compartments in the model and give sufficient conditions for coexistence of these two forms.

Adaptive laboratory evolution of Clostridium autoethanogenum to metabolize CO2 and H2 enhances growth rates in chemostat and unravels proteome and metabolome alterations

Microbial Biotechnology
Gas fermentation of CO2 and H2 is an attractive means to sustainably produce fuels and chemicals. Clostridium autoethanogenum is a model organism for industrial CO to ethanol and presents an opportunity for CO2‐to‐ethanol processes. As we have previously

Chemostat Model with Periodic Nutrient Input Described by Fourier Series

, 2020
Journal ArticleIn this paper we present a periodic Chemostat model of two species competing for a single nutrient available in limiting supply. The nutrient input is varied periodically using a Fourier series function to take into account the changing ...

Analysis of a model of flocculation in the chemostat

, 2017
Dans ce travail, on considère un modèle du chémostat incluant une seule espèce composée de bactéries planctoniques et attachées en compétition pour une seule ressource. Nous étudions ce modèle de floculation avec des taux de croissance monotones et le même taux de disparition.
