Cell Population Modelling Of Yeast Glycolytic Oscillations, Michael A. Henson, Dirk Muller, Matthias Reuss Dec 2002

Cell Population Modelling Of Yeast Glycolytic Oscillations, Michael A. Henson, Dirk Muller, Matthias Reuss

Michael A Henson

We investigated a cell-population modelling technique in which the population is constructed from an ensemble of individual cell models. The average value or the number distribution of any intracellular property captured by the individual cell model can be calculated by simulation of a sufficient number of individual cells. The proposed method is applied to a simple model of yeast glycolytic oscillations where synchronization of the cell population is mediated by the action of an excreted metabolite. We show that smooth one-dimensional distributions can be obtained with ensembles comprising 1000 individual cells. Random variations in the state and}or structure of individual …

Dynamics And Control Of Cell Populations In Continuous Bioreactors, Prodromos Daoutidis, Michael A. Henson Jan 2002

Dynamics And Control Of Cell Populations In Continuous Bioreactors, Prodromos Daoutidis, Michael A. Henson

Michael A Henson

Continuous bioreactors are critical unit operations in a wide variety of biotechnological processes. While they can be viewed as chemical reactors, bioreactors offer unique modeling and control challenges due to the complexity of the underlying biochemical reactions and the distributed properties of the cell population. The dynamic behavior of continuous bioreactors can be strongly affected by variations between individual cells that are captured only with cell population models. The objective of this paper is to outline recent progress in dynamic analysis and feedback control of continuous bioreactors described by cell population models. The industrially important process of continuous yeast production …


Cell Population Modeling And Parameter Estimation For Continuous Cultures Of Saccharomyces Cerevisiae, Prashant Mhaskar, Martin A. Hjortse, Michael A. Henson Jan 2002

Cell Population Modeling And Parameter Estimation For Continuous Cultures Of Saccharomyces Cerevisiae, Prashant Mhaskar, Martin A. Hjortse, Michael A. Henson

Michael A Henson

Saccharomyces cerevisiae is known to exhibit sustained oscillations in chemostats operated under aerobic and glucose-limited growth conditions. The oscillations are reflected both in intracellular and extracellular measurements. Our recent work has shown that unstructured cell population balance models are capable of generating sustained oscillations over an experimentally meaningful range of dilution rates. A disadvantage of such unstructured models is that they lack variables that can be compared directly to easily measured extracellular variables. Thus far, most of our work in model development has been aimed at achieving qualitative agreement with experimental data. In this paper, a segregated model with a …

De Novo Design Of Biomimetic Antimicrobial Polymers, Gregory N. Tew, Dahui Liu, Bin Chen, Robert J. Doerksen, Justin Kaplan, Patrick J. Carroll, Michael L. Klein, William F. Degrado

Gregory N. Tew

The design of polymers and oligomers that mimic the complex structures and remarkable biological properties of proteins is an important endeavor with both fundamental and practical implications. Recently, a number of nonnatural peptides with designed sequences have been elaborated to provide biologically active structures; in particular, facially amphiphilic peptides built from β-amino acids have been shown to mimic both the structures as well as the biological function of natural antimicrobial peptides such as magainins and cecropins. However, these natural peptides as well as their β-peptide analogues are expensive to prepare and difficult to produce on a large scale, limiting their …
