title: PCR-based method using propidium monoazide to distinguish viable from nonviable Bacillus subtilis spores.
abstract: This paper describes a molecular-based method which is able to discriminate between viable and inactivated Bacillus subtilis spores by utilizing the DNA-intercalating dye propidium monoazide. The approach should be valuable in our attempt to employ molecular methods to streamline the evaluation of process validation using bacterial endospores.
