✦ Synopsis

Viability of spores of Bacillus cereus was totally inhibited at 85°C over 30 min by adding 0.4% (w/v) potassium sorbate with 6% (w/v) NaCl at pH 4.5. Viability of B. stearothermophilus spores was totally inhibited at 95°C for 45 min in a buffer at pH 4.2 containing 0.8% (w/v) potassium sorbate and 8% (w/v) NaC1. A synergistic inhibitory effect was demonstrated in some of the combinations. The inhibition may be due to interference with the heatresistance apparatus of the spores.
