AgSiO2, ZnAg and Ag-Zeolite were investigated for antimicrobial activity using Gram-negative Pseudomonas aeruginosa, Shewanella putrefaciens and Gram-positive Clostridium, Listeria monocytogens as target microorganisms by disk diffusion and Agar plate MIC method. These bacteria are responsible for microbiological and chemical spoilage of sea food mainly and from the result we found that Silver zeolite, AgSiO2 has good antimicrobial activity for all target microorganisms except for clostridium perfringem. ZnAg has also shown good antimicrobial properties against all target microorganisms except Listeria monocytogens. Only ZnAg is capable to reduce clostridium perfringem as compare to Silver zeolite and AgSiO2.
