About the BacT/Alert 3D Technology

BioMerieux developed the BacT/Alert 3D microbial detection system as a fully automated system built on their patented colorimetric technology that detects microorganisms’ growth by tracking CO2 production. The system incubates, agitates, and with solid-state reflectometers, continuously monitors the status of each culture bottle for microbial growth.

If microorganisms are present in the test sample, CO2 is produced as the microorganisms metabolize the substrate found in the culture medium. When growth of the microorganism produces CO2, the color of the sensor located in the bottom of each culture bottle changes from dark to light. A light emitting diode (LED) projects light onto the sensor, which is then reflected and measured by a photodetector.

There are several advantages to this technology including the testing timeline. Timelines for releasing sample results are <11 days, compared to the 14 day incubation required for compendial sterility. In addition, turbidity that may occur in the sample due to the presence of cellular components or debris does not have an impact on the results of the system. This makes the system suitable for testing a wide range of products.

The BacT/Alert 3D system accommodates varying sample types, sample sizes, enrichment broths, and volumes. With faster micro screening and shorter production cycle times, this method delivers significant cost savings and efficiencies.

The Rapid Sterility Test performed by Eurofins BioPharma Product Testing is referred to as BacT Test and is intended to serve as a Rapid Contamination Check with a method that was validated in accordance with USP <1223>. While the BacT test was determined to be non-inferior to the USP <71> test, it is not a replacement for the USP <71> test.
