title: High-pressure inactivation of Bacillus cereus spores in the presence of argon.
abstract: We investigated the high-pressure inactivation of Bacillus cereus spores in water containing argon. At the pressure of 600 MPa, addition of argon accelerated the inactivation of spores at 20 degrees C, but had no effect on the inactivation at 40 degrees C. The influence of added argon on inactivation of the spores was marked under conditions with a strong 'water ordering' effect. The pressure resistance of B. cereus spores was thus shown to be affected by 'water ordering'.
