- Аннотация: In the present work, we studied hyperchromism/hypochromism in the chlorosomal BChl c Q/B absorption bands of the green photosynthetic bacterium Chloroflexus (Cfx.) aurantiacus. These chlorosomes were isolated from cells grown under different light intensities and therefore had different sizes of BChl c antennae and their unit building blocks. We showed experimentally that the Q/B-band hyperchromism/hypochromism is proportional to the size of the chlorosomal antenna. We explained theoretically these findings in terms of excitonic intensity borrowing between Q and B bands for the J-/H-aggregates of the BChls.
