Energy and electron transfer in bacterial reaction centers

Bacterial Reaction centers (bRCs) from photosynthetic bacteria are pigment-protein complexes responsible for initial charge separation steps of photosynthesis. Their simple structure as well as high energy and charge transfer efficiency, which are not fully understood yet, makes bRCs one of the most important and most investigated photosynthetic systems in the world.

The main aim of this project is to investigate bRCs from two different organisms: purple bacteria Rhodobacter sphaeroides and green bacteria Chloroflexus aurantiacus, using two dimensional electronic spectroscopy at cryogenic temperature (77K). The fine temporal resolution of the study should reveal detailed features of the initial energy transfer steps as well as provide insights of charge separation dynamics.
