3M™ Petrifilm™ Lactic Acid Bacteria Count Plate 6461, 50 per box

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.

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.
