Abstract:
:The present Mössbauer spectroscopic studies of isolated bacterioferritin and whole cells of Pseudomonas aeruginosa have shown that the iron core of bacterioferritin is not altered on isolation. These studies have also shown that the bacterioferritin core is typically 85% oxidized within the cell and may contain a significant proportion of its iron as small clusters during the early stage of the stationary phase of cell growth.
