| Outline of Final Research Achievements |
This study aimed to investigate behavior of high hydrostatic pressure (HHP)-injured bacteria during storage on standard method agar (SMA) or in Trypticase soy broth (TSB). For Escherichia coli and Salmonella enteridis, maximum numbers of these HHP-injured bacteria could be detected by cultivating on SMA at 25 degrees C of storage temperature respectively. While, detection numbers of these HHP-injured bacteria could be decreased according to elevating storage temperature. For E. coli and S. enteritidis and Listeria monocyotgenes, recovery of these HHP-injured bacteria could be occurred in TSB at lower temperature than these bacterial growth temperatures respectively. And, elevating temperature could activate the recovery of these HHP-injured bacteria.
