Enzyme-Catalyzed Reactions Using Enzymes Immobilized On Non-Spherical Particles, Alexander D. Redfearn
Enzyme-Catalyzed Reactions Using Enzymes Immobilized On Non-Spherical Particles, Alexander D. Redfearn
Honors Theses and Capstones
Modern and industrial chemical reactions often utilize enzyme-catalyzed reactions to increase product yields. Given the high cost of enzymes it is desirable to preserve the activity of the enzymes and reuse them several times. In this study, I explored the possibility of immobilizing enzymes on custom-made non-spherical SU-8 microparticles to conduct enzyme-catalyzed reactions in flow reactors. The decomposition of hydrogen peroxide using bovine liver catalase was studied due to its well-understood enzyme kinetics. Soft lithography techniques were used to synthesize prismatic SU-8 microparticles. I will discuss the progress that has been made in immobilizing the enzyme on the particle surface …

Photosynthesis, arguably the most important biological process on earth, solely relies on the ability of pigments to capture, utilize, and convert the sun‟s energy to form life. The adequate conversion of light into harvestable food, fuel, and fiber regulates rates of population and economic growth. In order to meet the expanding needs of humanity with the earth‟s potential for agricultural production, new sustainable techniques for increased photosynthetic efficiency in plants must be implemented. The earth's pattern of light exposure is extremely dynamic, exhibiting constant changes in quantity and quality throughout time and space. For photosynthetic organisms, this meant evolving various …

The capture of CO2 from flue gases can be done by chemical absorption with aqueous amine solutions like MEA (monoethanolamine). Although this is a proven process, there are still operational problems to overcome [1], namely those resulting from solvent degradation, precipitation, corrosion and foaming. Also, the absorption capacity of the most current amines must be improved in order to obtain a more profitable operation. It has been shown previously that relationships exist between the amine structure and the activity/capacity for CO2 absorption. The introduction of amine substituents at the α-carbon creates a carbamate instability, which causes the hydrolysis to go …
