Complex Intracellular Structures in Prokaryotes provides historical background and comprehensive reviews of ten topics that cover the spectrum of the complex intracellular structures of prokaryotes: proteasomes, phycobilisomes, chlorosomes, gas vesicles, carboxysomes, magnetosomes, intracytoplasmic membranes, membrane-bound nucleoids, anammoxosomes, and cytoarchitecture of Epulopiscium spp. Cameos of selected additional structures are presented to broaden the scope of the volume and to generate increased interest in these structures.
