Applications of Enzymes
Soluble and immobilized enzymes may find potential use in a variety of applications, including pharmaceutical production, pulp and paper processing, and wastewater treatment, to name a few. Research in this area is focused upon the development of applications of enzyme preparations, and the design and scale-up of reactors in which enzymes are used for specific industrial applications.
Biofuels and Bioenergy
Renewable energy sources such as ethanol, bio/renewable diesel and biogas are finding increased prominence, as we seek to supplement fossil fuels, reduce GHG emissions, and enhance the rural economy. Work in this area has focused on enzymes for conversion of starch and lignocellulosics into sugars, biofuels, and bioproducts, and upon biomass pretreatment methods needed to enhance enzyme hydrolysis of lignocellulosics. Also within this subject area, we aim to develop comprehensive process models of biofuel/bioenergy production systems, for the purposes of financial analysis and life cycle assessment.
Enzyme inactivation, inhibition and regulation of enzyme activity
Successful industrial use of enzymes is contingent upon the availability of a stable, low cost enzyme preparation. Some enzymes are subject to substrate-induced inactivation, whereby the exposure of the enzyme to a toxic substrate can lead to an irreversible loss of activity. The occurrence of inactivation and inhibition has significant implications upon industrial biochemical production and upon the sequential administration of drugs in humans. This work is aimed at investigating methods to improve enzyme function.
Drug distribution and elimination
In this research, fundamental principles in reaction kinetics and mass transfer are applied to develop a model of drug metabolism. The model is then used to determine drug/toxin distribution in organs such as the liver, kidney, or eyes. This may serve as a precursor to development and optimization of drug delivery systems. Current applications include the development a mathematical models of kidney dialysis.
