| Abstract | BIOSIS COPYRIGHT: BIOL ABS. The influence of nisin in combination with organic acids and pH on thermally stressed suspensions of five Bacillus species was examined. Heating at either 65? C for 60 min or 95? C for 15 min had little effect on spore viability in mineral acid treated control systems. Nisin was effective in preventing spore outgrowth, though its efficacy was adversely affected by high pH, high spore loads and high incubation temperatures. The four organic acids studied showed considerable variations in their effectiveness as antimicrobial agents, but can be ranked, in order of increasing efficacy, for each heat treatment as follows: citric acid and lt; latic acid and lt; glucono-delta-lactone (GDL) and lt; GDL and lt; lactic acids of nisin and organic acid markedly improved the stability of the preservation system over and above that of each preservative individually, particularly under less acidic conditions and ambient storage. |
