Photosystem I-Based Applications For The Photo-Catalyzed Production Of Hydrogen And Electricity, Rosemary Khuu Le
Doctoral Dissertations
The aim of this dissertation was to optimize systems integrating the photosystem I (PSI) redox protein, which is involved in photosynthesis, with noble metals for electron transfer to show its versatility: 1) in solution coupled with platinum to mediate hydrogen evolution and 2) on a planar gold surface for electricity production.
Response surface methodology was utilized to study variables that affect hydrogen (H2) yield from platinized-PSI. Light intensity, temperature, and platinum concentration were varied during the platinum-photo-reduction process. Analysis of the effects of the variables on H2 yield allowed for determination of a condition for optimized hydrogen …

Doctoral Dissertations
Photosystem I (PSI) is a membrane protein involved in the photosynthetic cycle of plants, algae, and cyanobacteria that is of specific interest due to its ability to harness solar energy to generate reducing power. This work seeks to form an in vitro hybrid protein fusion between the membrane integral PSI protein and the membrane-bound hydrogenase (MBH) enzyme, in an effort to improve electron transport between these two proteins.
Small-angle neutron scattering (SANS) was used to characterize the detergent-solubilized solution structure of trimeric PSI from the cyanobacterium Thermosynechococcus elongatus, which showed that the detergent interacts primarily with the hydrophobic periphery …
