Trace Analytics offers a variety of microbial analyses including Total Aerobic Plate Count, Total Anaerobic Plate Count, Total Fungal Count, Gram’s staining, chromogenic identification, and phenotypic identification. When a customer is testing to a standard where the number and cell shape (presumptive identification) of the microorganism is no longer sufficient information, confirmatory identification testing can be applied. The Biolog microbial identification system can provide additional answers for users looking for more information about their found microbe.
Each genus and species of organism has specific sensitivities to certain chemicals, enzymes, and drugs, as well as the ability to metabolize certain compounds. Trace Analytics can test for different properties exhibited by varying bacteria, yeast, and filamentous mold to “fingerprint” the organism. Our 17025 accredited laboratory is able to identify within its fingerprint library of over 2,900 species. The Biolog system was created specifically for applications in quality control and environmental monitoring – focusing on microorganisms that are more prevalent and pertinent outside of the clinical setting.
The Biolog testing process is streamlined and straightforward. The organism is first obtained or may be re-streaked on a different plate for culture isolation and viability purposes. Once isolated, the pure culture is transferred into an inoculum fluid, mixed well, and then inoculated into each well of the MicroPlate. The plate is incubated prior to analysis on the Biolog, with time and temperature depending on the microorganism. The Biolog is installation, operation, and performance validated using standard reference microorganisms certified by the accredited American Type Culture Collection. The Biolog is also 21 CFR Part 11 compliant, a code by the Food and Drug Administration regulating electronic records and signatures for audit trail traceability purposes.
Confirmatory testing is required for select environmental monitoring microbial specifications like USP 797. Compared to presumptive testing, which identifies only present or not detected rather than true identification, results can provide multifaceted detail on what microorganisms are present in your facility or compressed air system.
