Biosafety Icon BSL 1

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Medium
Instruction for complete medium
ATCC Medium 1773 inoculated with Klebsiella pneumoniae subsp. pneumoniae (ATCC® 700831) or Enterobacter aerogenes (ATCC® 13048).

Incubation
Grown with Enterobacter aerogenes ATCC 13048 and mixed bacteria.
Culture maintenance
1.   Prepare bacterized ATCC medium 1773.

2.   When the culture is at or near peak density, rub the surface of the tube with a sterile cotton swab, and agitate the swab to dislodge the adherent cells.  Invert gently 10 times to distribute cells evenly.

3. Transfer approximately 0.25 ml to a 16 x 125 mm screw-capped test tube containing 12 ml of fresh ATCC medium 1773. 

4.   Screw the cap on tightly and incubate on a 15° horizontal slant at 25°C.

Cryopreservation

1.   Harvest the cells from a culture that is at or near peak density by centrifuging at 850 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 850 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 20% (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 10% (v/v) DMSO. The time from the mixing of the cell preparation and DMSO stock solution before the freezing process is begun 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 sufficient to cover the frozen material. Do not agitate the vial.

9.   Immediately after thawing, aseptically remove the contents of the ampule and inoculate into 12 ml of fresh ATCC medium 1773 in a 16 x 125 screw-capped test tube.  Incubate on a 15° horizontal slant at 25°C.
