CCM quality control strains

All quality control strains are supplied in the form of a lyophilized culture and selected group of quality control strains is supplied also on gelatin disks.

Cultures on gelatin disks

Gelatin disks replace the storage of cultures on agar. This reduces the risk of contamination and loss of viability during subculturing. They give standard results of controlled tests. They are supplied in screw cap vials that allow for easy, aseptic and repeatable culture collection. Each vial contains 20 discs. The expiration period is 1-2 years. The CCM reserves the right to use up to half of the total expiration date. Discs should be protected from light and moisture and stored in a refrigerator at 2 to 8 °C. Gelatin disks are shipped under common transport conditions.
