All Salmonella typhimurium strains tested were able to use iron from transferrin. In buffered nutrient broth — poor in iron‐content — the strains were tested in 59 FeCl 3 and 59 Fe‐transferrin uptake in different growth phases. In the early log phase the strains are able to catch the 59 Fe 3+ in a very great amount as it is necessary for the growth. The content of 59 Fe per cell was in the late log phase reduced until to a value, which seen to be enough for growth. The acquisition of 59 Fe‐transferrin between the early and late log phase tested by 4 S. typhimurium strains was different.
