• The effect of low hydrostatic pressure （30, 50 and 100 MPa） （LHP） treatment on the inactivation of B. subtilis, B. licheniformics and B. coagulans spores in combination with heat treatment at 75℃ was investigated. The inactivation of spores was in proportion to the increase of treatment pressure at 75℃. B. licheniformis spores were more resistant than those of the other two strains to LHP treatment combined with heat treatment at 75℃. The hydrostatic pressure above 50 MPa and the treatment time at least 700 min were necessary to inactivate B. lichenifomis spores by five log-cycles.
