| Abstract: | The effect of food-grade sodium acid pyrophosphate (SAPP) alone or in combination with potassium sorbate (PS) on growth and toxin production by an enterotoxin A producing strain of Staphylococcus aureus was investigated. Growth of cultures was monitored by absorbancy readings (640 nm) at 5-hr intervals. Toxin production was determined by an Enzyme Linked Immunosorbent Assay (ELISA). SAPP (0.04%) in combination with PS (0.26%) was the most favorable treatment for inhibition of S. aureus growth. Concentration of toxin correlated with amount of growth in all treatments studied. |
