Abstract:

Rhodopseudomonas palustris is a photosynthetic bacterium that has good potential to be developed as a biocatalyst for the production of hydrogen, a biofuel. The goal of this project is to conduct basic studies that will facilitate the development of a process wherein Rhodopseudomonas cells grown on surfaces as biofilms, produce hydrogen with energy provided from sunlight and electrons derived from agricultural waste. We characterized hydrogen production by Rhodopseudomonas, started to characterize biofilm formation by this species and initiated studies to identify the structure of a chemical signal that may activate expression of genes important for biofilm formation by Rhodopseudomonas.
