ABSTRACT

Anti-bacterial mechanism for complete-ionized Ag⁺, Cu²⁺, Zn²⁺ ion solutions has been established against S. aureus and E. coli. Anti-bacterial mechanism against S. aureus is involved that bacterolysis and destruction of S. aureus cell wall occur by inhibition of PGN elongation through metallic Ag⁺, Cu²⁺, Zn²⁺ ions-induced PGN inhibitive transglycosylase (TG) and transpeptidase (TP) syntheses (TG for Zn²⁺) and PGN activated major autolysin of amidase. The other, anti-bacterial mechanism against E. coli has been clarified that bacteriolysis and destruction of E. coli cell wall occur by disruption of E. coli outer membrane (OM) structure with OM lipoprotein-endopeptidase activation, and by inhibition of PGN elongation through inhibitive TG and TP syntheses (TG for Zn²⁺) and PGN activated major autolysins. Ag⁺, Cu²⁺, Zn²⁺ ions-induced ROS generation of O₂- and H₂O₂ and ROS-mediated oxidative stress in bacterial cell lead to killing by stress damage for silver ions, cell membrane damages due to high reactive •OH and OH^－ are formed by Haber-Weiss and Fenton reactions for Cu²⁺ ions, and DNA molecular damage for Zn²⁺ ions.
