Synergetic killing effects of mild heat and high hydrostatic pressure on spores of bacillus were studied using colorimetric assay.The results indicated that the rates of leakage of 2,6-pyridinedicarboxylic acid from spores ofB.subtilis and B.stearothermophilus treated with mild heat and high hydrostatic pressure were increased significantly (P < 0.05).Under several treatment groups (at 50℃,60℃,70℃ and 550 MPa,600 MPa),PDA leakage of spores of B.subtillis and B.stearothermophilus was not different strongly from control group (121℃,30 min) (P > 0.05),structures of spores were destroyed completely,and permeability barriers of spores were demolished.
