The kinetics of the release profile of silver ions from zeolite X framework and its effect on fatty acid composition of two gram-negative: Escherichia coli K12 W-T and Pseudomonas aeruginosa NCIMB 8295 and one gram-positive Staphylococcus aureus NCIMB 6571. Silver ions were released from the zeolite framework in an anomalous manner with time. The fatty acid composition was significantly altered when they were exposed to silver-loaded zeolite X. Interaction of silver ions with fatty acid of bacterial cells is likely to affect the survival of the cell
