Effect of cell retention techniques in Komagataella phaffii lab‐scale continuous processes
Biotechnology Progress, Volume 42, Issue 2, March/April 2026.Abstract Perfusion technologies play a growing role in the implementation of continuous processes for biotherapeutics production in mammalian‐based manufacturing. However, their application to alternative production hosts is limited. Cell retention systems are of key importance for the efficiency of perfusion bioreactors.

Resource quantity affects infection success and impacts of a microsporidian on hosts
Oikos, Volume 2026, Issue 2, February 2026.Resource quantity in the environment often changes over time and influences the nutritional status of hosts that may encounter parasites. If resource availability significantly alters both infection success and within‐host growth of a parasite, fluctuations in resources may underlie the seasonal disease outbreaks that have been observed for some ...

Stability of a chemostat model of two microorganisms [PDF]
, 2006 We studied stability analysis of a chemostat model of two microorganisms that incorporates both different response functions and we made a single code of the model using a computer algebra system (CAS) Mathematica for graphical illustration ...

Threshold Dynamics of a Stochastic Chemostat Model with Two Nutrients and One Microorganism [PDF]
, 2017 A new stochastic chemostat model with two substitutable nutrients and one microorganism is proposed and investigated. Firstly, for the corresponding deterministic model, the threshold for extinction and permanence of the microorganism is obtained by ...

Global Behaviors of a Chemostat Model with Delayed Nutrient Recycling and Periodically Pulsed Input
Discrete Dynamics in Nature and Society, 2010 The dynamic behaviors in a chemostat model with delayed nutrient recycling and periodically pulsed input are studied. By introducing new analysis technique, the sufficient and necessary conditions on the permanence and extinction of the microorganisms ...

Complex Dynamics in a Tritrophic Chain Model With Prey Stage Structure
Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.A tritrophic chain model with prey stage structure (reproductive and nonreproductive classes) is analyzed. This model is provided by an ODE system of dimension four and the main premise consists in assuming that the interaction between reproductive population and predator is governed either by a functional response Holling type II or IV (where a ...
