LABORATORY PROCEDURES FOR MICROORGANISMS
M/1998/3.02 Appendix 7
If a new deposit is accepted it should be preserved as quick as possible. In addition, new batches of earlier preserved cultures have to be prepared as a result of low or due to significant loss in viability of the preserved strain. Appropriate strain data are recorded in the Preservation Book or the computer database. Each laboratory responsible for the preservation of microorganisms keeps a separate Preservation Book or is responsible for the entry into the computer database.
An example of a single page of a Preservation Book is shown on page 2. Each page of the book should be numbered serially.
1Reason for preservation: ND new deposit LS low stock LV low viability 2 Kind of preservation : LN Liquid nitrogen FD Freeze drying LD Liquid drying VD Vacuum drying F70 Freezing at -70C
