The Biohydrogen team in the Swartz Lab focuses on developing Biotechnology-based solutions to the global energy problem. Specifically, we are interested in developing sustainable processes for the production of hydrogen from (1) Sunlight and (2) Biomass (see below).

The Biohydrogen team currently consists of Phil Smith, Alyssa Bingham, Kunal Mehta, Stacey Shiigi, and Sylvie Liong. Former members of the group include Marcus Boyer, James Stapleton, and Jon Kuchenreuter.

Early research by our team focused on building methods to produce active [FeFe] hydrogenases. These proteins catalyze the interconversion of protons, electrons, and dihydrogen; they are especially oxygen-sensitive due their FeS chemistry. [papers]

The first major goal of this research was the evolution of an oxygen-tolerant [FeFe] hydrogenase. This has proven to be extremely difficult; indeed many other research groups have tried this and been ultimately unsuccessful. However, our evolution methodology [papers] is different and has led to some level of success in this endeavor [paper]; however, much remains to be done to achieve this overall objective.
