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.

Handling information

Handling procedure
1. Open the vial according to enclosed instructions.

2. From a tube of #2138 broth (5 to 6 ml), withdraw approximately 0.5 with a sterile pipette; add this medium to the vial to rehydrate the entire pellet.

3. Aseptically transfer the contents of the vial into the broth tube.  Mix well.

4. Use several drops of the suspension to inoculate a #2138 agar slant and/or plate.

5. Incubate all tubes and plate at 28°C for 24-48 hours.

Handling notes
Silicibacter pomeroyi is a very small Gram-negative rod that is motile.  Colonies on #2138 agar are circular, entire, translucent and raised.  Under a dissecting microscope the colonies have a silvery appearance like drops of mercury.
