Mode of bactericidal action of silver zeolite and its comparison with that of silver nitrate

Appl Environ Microbiol. 2003 Jul;69(7):4278-81. doi: 10.1128/aem.69.7.4278-4281.2003.


The properties of the bactericidal action of silver zeolite as affected by inorganic salts and ion chelators were similar to those of silver nitrate. The results suggest that the contact of the bacterial cell with silver zeolite, the consequent transfer of silver ion to the cell, and the generation of reactive oxygen species in the cell are involved in the bactericidal activity of silver zeolite.
