Developing SAL6 Sterility

NovaKillGen2 (mL)	Preconditioning time (h)	ScCO2 exposure (h)	Number of positive samples

The NovaKill Gen2 additive amount was held constant, while length of conditioning and ScCO₂ exposure varied. All samples inoculated with 106 Bacillus atrophaeus. A positive sample represents growth on an agar plate.

ScCO₂, supercritical carbon dioxide.
