Iron Content, Iron Speciation and Phycocyanin in Commercial Samples of Arthrospira spp.

ABSTRACT: Cyanobacteria are characterized by high iron content. In this research, we collected ten commercial samples of Arthrospira spp. sold as food supplement to determine iron content and assess whether iron speciation showed variability among samples and changed respect to A. platensis grown in controlled conditions. Particular attention was also paid to phycocyanin, as an iron-binding protein. In six of the ten samples, 14 essential and non-essential trace elements were analysed using ICP-MS. Iron content measured in samples using atomic absorption spectrometry (AAS) varied from 353 (sample S5) to 1459 (sample S7) µg g^-1 dry weight and was in the range of those reported by other authors in commercial supplements. Iron speciation was studied using size exclus
