Fluorescence emission spectroscopy of a single light harvesting chlorosome from green filamentous photosynthetic bacteria

摘要

Green photosynthetic bacteria have a unique light harvesting antenna called chlorosome. In chlorosomes, bacteriochlorophyll(BChl)s-c, d or e self-aggregate to form rod-like apparatus. Light energy is absorbed by BChl aggregates, which is transferredto a reaction center via baseplate (BChl-a/protein complex in a chlorosomal membrane), converting into chemical energy available for living bacteria.
