Documentation

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.

General

Specific applications

MicroQuant™ products are available in both high and low CFU formats. Selection of low or high CFU MicroQuant™ products would be dictated by the guidelines for the microbial QC test being performed and the amount of material needed to execute such tests.

Characteristics

Comments

MicroQuant™ strains are best-in-class controls developed to support USP General Chapters. These precisely quantitated controls are provided in a single-use format that rehydrates immediately and is easy to use and convenient to store.

CA Dunlap et al. reclassified Bacillus subtilis subsp. spizizenii into the new species Bacillus spizizenii.  Some platforms and databases may still identify this species by its previous name.

Handling information

Handling procedure
  1. Remove the desired number of cryopreserved reference culture vials (gray crimp) and rehydration buffer vials (green crimp) from 2-8°C storage and place into a biosafety cabinet.  One vial of rehydration buffer should be used for each vial of reference culture.
  2. Uncap each vial. Add 1.0 mL of rehydration buffer to the reference culture vial. Recap the vial and allow the pellet to dissolve for 30 seconds. 
  3. Vortex on high for 30 seconds to ensure the suspension is well mixed. The suspension is now useable and contains 100-1000 CFU per 1.0 mL.
  4. Uncap the vial and pipette 100 µL of the resuspended reference culture directly on a non-selective media agar plate. If following a specific pharmacopeial chapter, use the appropriate media specified.
    Note: ATCC quantitation results were obtained using 100 mm Tryptic Soy Agar plates with 1.5% Tryptone, 0.5% Soytone, 0.5% Sodium Chloide, and 1.5% Agar (plates were procured from Teknova®).
  5. Use a sterile plate spreader (not provided) to spread the sample evenly over the surface of the media plate. Do not use glass beads. Incubate the plates in an incubator at the appropriate temperature (see the product page or product sheet). If following a specific pharmacopeial chapter, use the incubation conditions specified. 
  6. Following incubation, count the number of visible colonies on the plate.
Handling notes
For applications outside of compendial assays, please refer to the product page for ATCC 6633 for standard growth conditions.
