Inclusions in Prokaryotes provides historical background and comprehensive reviews of eight well-known prokaryotic inclusions: sulfur globules, polyphosphate granules and acidicalcisomes, glycogen, polyhydroxyalkonate granules, wax ester and triacylglycerol inclusions, cyanophycin, insecticidal protein crystals, and protein inclusion bodies of recombinant bacteria. In addition, cameos of selected less-studied inclusions are presented to generate renewed and continuing interest.
