The seemingly homogeneous metachromatic and electron-scattering granules of Corynebacterium diphtheriae have two structural components as revealed under conditions of low beam load and by use of ribonuclease. They contain high percentages of P and Ca. Findings point to participation of ribosomes and intracytoplasmic membranes in the formation of the granules.
