The 3M™ Petrifilm™ Lactic Acid Bacteria Count Plate is a self-contained, sample-ready-culture-medium system which contains nutrients, selective agents, a cold-water-soluble gelling agent, and a tetrazolium indicator that facilitates colony enumeration. The plate contains oxygen scavenging compounds which create an anaerobic environment for the recovery of homofermentative and heterofermentative lactic acid bacteria in the food and beverage industries.

Details

•Self-contained anaerobic environment enabled by oxygen-scavenging technology and oxygen-barrier films. No gas packs, chambers, or CO₂ incubators needed.
•Results in 48 hours of incubation time.
•Ready-to-use plates eliminates the need for labor intensive media preparation, special diluents and sample pH adjustment.
•All-in-one method for differentiation of gas-producing colonies without Durham tubes or extra steps.
•Proven reliability versus MRS and APT agar methods. Can be used to test a broad range of foods and environmental samples.
•3M™ Petrifilm™ Plates use 75% less energy, use 79% less water, produce 75% less greenhouse gases and result in 66% less waste (by weight and volume) compared to competitive agar methods.
•Companies worldwide trust 3M Petrifilm Plates to provide accurate, efficient, consistent results

Introducing the first self-contained anaerobic plates for lactic acid bacteria testing: 3M™ Petrifilm™ Lactic Acid Bacteria Count Plates.

Every day, food processors, retailers and consumers are forced to throw out food spoiled with lactic acid bacteria. These normally useful bacteria can cause undesirable changes to ready-to-eat meats and seafood, dressings and sauces, vegetables and many other processed foods. This not only contributes to food waste and costly recalls, but can also damage your brand reputation.

3M science brings you a better way to test for lactic acid bacteria in your food products, raw materials and production environment without the hassle of traditional agar methods – 3M™ Petrifilm™ Lactic Acid Bacteria Count Plates. These ready-to-use plates simplify the testing process and give accurate results in less time, helping you reduce waste, minimize recalls and protect your reputation in the marketplace.

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.
