Preservation system with freezing medium for the long-term storage of bacterial cultures. The unique technique uses porous beads as a carrier for microorganisms to preserve them simply and safely by freezing. It is a universal method that minimizes cross-contamination and prevents genetic variation of the microorganisms. The cryotubes inoculated with a pure culture should be stored at -25 °C, -30 °C, -35 °C, or down to -80 °C for best long-term results.
Some fastidious microorganisms and specific fungi can be affected negatively by low temperatures. It is therefore recommended to perform specific tests for special strains. |
