Differentiation of polyphosphate and poly-beta-hydroxybutyrate granules in an Acinetobacter sp. isolated from activated sludge.
Cells containing polyphosphate 71 micrograms P (mg protein)-1 and no poly-beta-hydroxybutyrate showed metachromatic granules but no lipid granules; cells containing poly-beta-hydroxybutyrate (15% of dry weight) showed fluorescence lipid granules but no metachromatic granules; whereas cells containing both polyphosphate and poly-beta-hydroxybutyrate showed both types of granules. These observations, together with a critical review of the literature, show a clear distinction between metachromatic (or volutin) granules and lipid granules.
