title: The evaluation of the recovery capacity of media for heat-treated Bacillus stearothermophilus spore strips.
abstract: Six media were assessed for their capacity to recover spores of Bacillus stearothermophilus from three commercially available types of spore strip heated for up to 5 min at 121 degrees C in steam. All media recovered similar numbers of spores from unheated strips; however, there was considerable difference in survivor counts when the media were used to recover heated spores. Media containing starch consistently recovered the highest number of spores. The greatest difference in recovery capacity between the media was observed when spore strips were heated for 5 min at 121 degrees C.
