The exploration of the antibacterial mechanism of fe3+ against bacteria

Sun, Hong-qiLu, Xue-meiGao, Pei-ji

This study demonstrated that the bacteria could adsorb Fe3+ and reduce Fe3+ to Fe2+. Iron had significant bacteriostatic effects, which were directly proportional to the iron concentration and under the influence of pH and chelator. It presumed that the inhibition of Fe3+ acts through the formation of hydroxyl free radicals.

1. hydroxyl radical
2. chelator
3. siderophore
4. antibacterial activity
5. ferric ion
