Glucose protects the cell membrane, Na+/K+-ATPase, nucleic acids, and proteins in Bacillus subtilis spores under high pressure thermal sterilization.

The extreme resistance of bacterial spores to sterilization makes them a major concern to the food industry and consumers. In this study, the effect of glucose on the inactivation of Bacillus subtilis spores by high pressure thermal sterilization (HPTS) was evaluated. The results showed that the protective effects of glucose increased with the increase in its concentration.
