Abstract:

The study was conducted to determine the storage requirements for ampouled media and to compare these results to those obtained with dehydrated media stored under similar conditions. Results obtained after 22 months of testing indicated that storage temperature rather than exposure to light is the critical factor causing deterioration of the ampouled media. Little apparent deterioration was noted when the media was stored either under refrigeration 4C or at room temperature 22-24C. However, less than 50 percent of the coliforms incubated on ampouled media were detected after ten months storage at 35C. Author
