Location of Chlorophyll in Rhodospirillum Rubrum.

Holt, Stanley C. (University of California, Davis), and Allen G. Marr. Location of chlorophyll in Rhodospirillum rubrum. J. Bacteriol. 89:1402-1412. 1965.-If cells of Rhodospirillum rubrum are broken by sonic and ballistic disruption, the chlorophyll is not found in discrete cytoplasmic structures, but is located in a more extensive structure of the cell, the intracytoplasmic membrane. Direct electron microscopy of sonically disrupted cells of R. rubrum and stereo-electron microscopy of osmotically shocked cells reveal the presence of a tubular network of internal membranes originating from the periphery of the cell.
