Aerobic growth with synchronous cell division was induced in Rhodospirillum rubrum by starvation methods. Cells were harvested at different points in the cell cycle. Analysis of the composition of the cell envelope prepared by differential centrifugation or density gradient-purified cytoplasmic membrane obtained from cells at different times indicated that the protein/phospholipid ratio fluctuated with the cell cycle. The protein/phospholipid ratio of cell envelope from selection-synchronized cells also fluctuated with the cell cycle. These studies indicate that the phenomenon of cell-cycle-dependent fluctuation in membrane composition is not restricted to the intracytoplasmic chromatophore membrane of phototrophic cells.
