Taxonomic description
Medium ATCC® Medium 1171: TYGM-9 medium
Growth Conditions
Temperature: 25°C
Culture System : Xenic, grown with mixed bacteria in the dark. Dilute ATCC medium 1171 1:20 in artificial seawater.
Cryopreservation Harvest and Preservation
  1. Harvest the cells from a culture that is at or near peak density by centrifuging at 900 x g for 5 minutes.
  2. If the cell concentration exceeds the required level do not centrifuge, but adjust the concentration to between 2 x 106 and 2 x 107 cells/ml with fresh medium.  If the concentration is too low, centrifuge at 900 x g for 5 min and resuspend the pellet in the volume of fresh medium required to yield the desired concentration.
  3. While cells are centrifuging prepare a 15% (v/v) solution of sterile DMSO as follows: Add the required volume of DMSO to a glass screw-capped test tube and place it in an ice bath.  Allow the DMSO to solidify.  Add the required volume of refrigerated medium.  Dissolve the DMSO by inverting the tube several times.
    NOTE: If the DMSO solution is not prepared on ice, an exothermic reaction will occur that may precipitate certain components of the medium.
  4. Mix the cell preparation and the DMSO in equal portions. Thus, the final concentration will be between 106 and 107 cells/ml and 7.5% (v/v) DMSO. The time from the mixing of the cell preparation and DMSO stock solution to the start of the freezing process should be no less than 15 min and no longer than 30 min.
  5. Dispense in 0.5 ml aliquots into 1.0 - 2.0 ml sterile plastic screw-capped cryules (special plastic vials for cryopreservation).
  6. Place vials in a controlled rate freezing unit. From room temperature cool at -1°C/min to -40°C. If freezing unit can compensate for the heat of fusion, maintain rate at -1°C/min through heat of fusion. At -40°C plunge ampules into liquid nitrogen.  Alternatively, place the vials in a Nalgene 1°C freezing apparatus.  Place the apparatus at -80°C for 1.5 to 2 hours and then plunge ampules into liquid nitrogen.  (The cooling rate in this apparatus is approximately -1°C/min.)
  7. The frozen preparations are stored in either the vapor or liquid phase of a nitrogen freezer.
  8. To establish a culture from the frozen state place an ampule in a water bath set at 35°C (2-3 min).  Immerse the vial just sufficiently to cover the frozen material. Do not agitate the vial.
  9. Immediately after thawing, aseptically transfer contents to a 16 x 125 mm screw-capped test tube containing 6-8 ml of ATCC Medium 1171 diluted to 5% strength in artificial seawater (ASW).
  10. Screw the cap on tightly and incubate on a 15° horizontal slant at 25°C.
  11. Follow the protocol for maintenance of culture.
