A Rosenzweig-MacArthur (1963) Criterion for the Chemostat
The Scientific World Journal, 2016 The Rosenzweig-MacArthur (1963) criterion is a graphical criterion that has been widely used for elucidating the local stability properties of the Gause (1934) type predator-prey systems.

Evolutionary Attractors in the Chemostat Model
SIAM Journal on Applied MathematicsWe consider the evolutive chemostat model with a continuous phenotypic trait of the micro-organisms that impacts both the specific growth rate and the yield conversion, and whose evolution is driven by a mutation kernel. We study the evolutionary attractors (EAs) for a general class of non-linear growth functions, without assuming that the dynamics of ...

Global dynamics of a delayed chemostat model with harvest by impulsive flocculant input
Advances in Difference Equations, 2017 A mathematical model describing continuous microbial culture and harvest in a chemostat, incorporating a control strategy and defined by impulsive differential equations, is presented and investigated.

Electronic Journal of Qualitative Theory of Differential Equations, 2015 On infinitesimally short time intervals various processes contributing to population change tend to operate independently so that we can simply add their contributions (Metz and Diekmann, The dynamics of physiologically structured populations, 1986, p. 3)

Thermodynamic Evaluation of Dual Substrate Growth
Biotechnology and Bioengineering, EarlyView.ABSTRACT Various C₁–C₂ compounds are increasingly available through electrochemical reduction of CO2. Although not always suitable as a sole substrate, these compounds can supplement a primary substrate like glucose to enhance microbial growth. Yet, the mechanisms underlying the effects of dual substrate consumption on growth rate and growth yield ...

Microbial Cell Factories, 2021 Background Pichia pastoris is a powerful and broadly used host for recombinant protein production (RPP), where past bioprocess performance has often been directed with the methanol regulated AOX1 promoter (P AOX1 ), and the constitutive GAP promoter (P ...

The power of many: when genetics met yeasts and high‐throughput
Biological Reviews, EarlyView.ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Stochastic Models for a Chemostat and Long-Time Behavior [PDF]
Advances in Applied Probability, 2013 We introduce two stochastic chemostat models consisting of a coupled population-nutrient process reflecting the interaction between the nutrient and the bacteria in the chemostat with finite volume. The nutrient concentration evolves continuously but depends on the population size, while the population size is a birth-and-death process with ...

Influence of diffusion and convection on the chemostat dynamics [PDF]
Компьютерные исследования и моделирование, 2012 Population dynamics is considered in a modified chemostat model including diffusion, chemotaxis, and nonlocal competitive losses. To account for influence of the external environment on the population of the ecosystem, a random parameter is included into
