    Abstract: Process for the production of a protein correlated with the diphtheric toxin which comprises culturing in a liquid nutrient medium having a concentration of iron ions of from 0.05 mu g/ml to 0.5 mu g/ml, at a temperature of from 30 DEG C. to 40 DEG C., in a neutral culturing environment and under aerobic conditions, a microorganism belonging to the Corynebacterium diphtheriae genus with two mutant phages encoding the protein correlated with the diphtheric toxin integrated in a nontandem mode in their chromosomes.
