(A and B) Antimicrobial activity of AS-48 against B. cereus LWL1 in combination with sodium nitrite (A) and sodium lactate (B). Cultures were not treated with AS-48 (circles) or were treated with 5 μg of AS-48 per ml (squares) or 10μg of AS-48 per ml (triangles) alone (open symbols) or in combination with chemical preservatives (solid symbols). (C and D) Antimicrobial activity of AS-48 (5 μg/ml) against B. cereus LWL1 (C) and B. cereus CECT 131 (D) in the presence of no sodium chloride (•) or sodium chloride at a concentration of 3% (▪) or 5% (▴). Cultures were also treated with sodium chloride alone (○, no sodium chloride; □, 3% sodium chloride; ▵, 5% sodium chloride).
