This work has conducted to the quantification of the different parameters responsible for the tuning of the absorption and stability of the light-harvesting bacteriochlorophyll molecules in antennae proteins from purple bacteria, and of the redox potential of the primary electron donor in bacterial reaction centers. In the last decade, I got involved in the study of the mechanisms of regulation of light energy collection in plants and algae. In the presence of excess illumination, energy traps quickly (in seconds) appear in their photosynthetic membranes to de-activate the excess excitation energy into heat. Since 2005, using ultrafast time-resolved absorption and vibrational spectroscopic methods, we proposed to explain this mechanism the molecular switch model, in which the pH gradient induced by photosynthetic activity triggers a conformational change of the light-harvesting protein, which open a de-excitation channel involving the silent lower energy excited state of a carotenoid molecule.
