Abstract
A method for detecting the presence of bacterial spores is described by measuring microbial metabolic activity over time. Spores are distinguished from vegetative cells and other microorganisms by detecting a burst of metabolic activity indicating germination of spores. This method may be used to detect bacterial spores in a commercial process system, such as a papermaking system within the time frame of a typical work shift.
