Description

<p>The control of bacterial spores resistant to sterilization is important for the microbiological safety and integrity of foods. Spores are considered sub-lethally injured during the sterilization process but remain alive and can germinate and grow under non-stress conditions during storage and distribution. In this study, Our research team aimed to establish a method to control such injured bacterial spores, the survival of injured Bacillus subtilis spores after heat or gamma-ray irradiation treatment was investigated. we compared the damage mechanisms of spores subjected to heat treatment and γ-ray irradiation and the developmental dynamics of the injured spores. This study found that γ-ray irradiation suppressed the generation of injured spores better than heat treatment.</p>
