3M™ Petrifilm™ Lactic Acid Bacteria Count Plates


The 3M™ Petrifilm™ Lactic Acid Bacteria Count Plate is a time-saving, sample-ready plate designed to determine total lactic acid bacteria populations in food and environmental samples. Anaerobic made easy. Now you can get true anaerobic results using standard aerobic incubation conditions.


The self-contained anaerobic environment in this plate enhances the recovery of lactic acid bacteria, providing fast, accurate results for effective control of product quality and shelf life.


Fast, accurate testing in just 3 steps:*

1. Inoculate with 1 mL of sample. Simply lift the top film, add the sample, and roll the top film down.

2. Incubate at the appropriate temperature (28°C to 37°C). The space saving design minimizes incubator space requirements.

3. Count the red colonies after 48 hours.


The 3M™ Petrifilm™ Lactic Acid Bacteria Count Plate is able to differentiate between homofermentative (non gas-producing) and heterofermentative (gas-producing) colonies.
