Abstract:

The results of a comparative study of two samples of the rhizobacterium Azospirillum brasilense (strain Sp245) prepared in different conditions and of human liver ferritin using Mossbauer spectroscopy with a high velocity resolution demonstrated the presence of ferritin-like iron (i.e. iron similar to that found in ferritin-like proteins) in the bacterium. Mossbauer spectra of these samples were fitted in two ways: as a rough approximation using a one quadrupole doublet fit (the homogeneous iron core model) and using a superposition of quadrupole doublets (the heterogeneous iron core model). Both results demonstrated differences in the Mossbauer parameters for mammalian ferritin and for bacterial ferritin-like iron. Moreover, some differences in the Mossbauer parameters were observed between the two samples of A. brasilense Sp245 related to the differences in their preparation conditions. (C) 2014 Elsevier B.V.
