Changes in the Antenna Composition of Chlorobium Limicola Growing in Continuous Culture

Green species of Chlorobiaceae contain either BChl c or d as main antenna pigments, though in some cases may coexist [1-3]. Inside the chlorosomes, BChl molecules exist as a series of aggregated homologs arranged as rod elements [3]. Chlorosome bacteriochlorophylls capture light energy, which is sequentially transferred to the RC through distinct excitation carriers: the BChl a chlorosome baseplate, FMO proteins, and the membrane bound BChl a-protein complexes [4].
