Numerous kinetic data for excitation energy decay in bacteriochlorophylls as well as extremely short lifetimes of excitations in dominating chlorosoma pigment exclude the possibility of an efficient migration of this energy from chlorosoma to the main intra-membrane photosystem of some green bacteria. Author discusses the main purpose and molecular mechanism which account for this inconsistency in huge, 3D chlorosoma and substantiates the conditions of cell growing under which this energy migration from chlorosoma may become efficient.
Key words: Green bacteria, chlorosoma, energy migration and trapping.
