Microbial Inactivation Kinetics of Bacillus atrophaeus Under Synergistic High-Vacuum UVGI and Pulsed VHP
This paper documents the lethal D-values of bacterial endospores exposed to pulsed vaporized hydrogen peroxide within a 10-7 mbar vacuum chamber. We demonstrate an enhanced log-6.5 reduction factor achieved at temperatures below 55°C, preserving optical sensor coatings and multi-junction solar cells.
