    Aerobic Procedure* for Lactic Acid Bacteria Testing

    • 3M™ Petrifilm™ Plates has an Aerobic Procedure for Lactic Acid Bacteria which utilizes the 3M™ Petrifilm™ Aerobic Count Plate supplemented with MRS (deMan, Rogosa and Sharpe) medium and a pH indicator to enumerate lactic acid bacteria in salad dressings, Ready-to-Eat meats, Ready-to-Eat salads and stainless steel surfaces.

      Food processors and reference labs have demonstrated feasibility relative to their current lactic acid bacteria testing with a simple 3 step procedure:

      1. Combine - MRS/pH indicator broth with food or environmental sample and place sample on the center of a 3M Petrifilm Aerobic Count Plate.

      2. Incubate - The space saving design maximizes incubator space.

      3. Enumerate - A red indicator dye in the plate reacts with growing bacteria allowing colony visualization. Acid producing bacteria produce a yellow zone (halo) around the colony.

      *3M Petrifilm Plate performance has not been evaluated with all combinations of microbial flora, incubation conditions and food matrixes. It is the user's responsibility to determine that any test methods and results meet the user's requirements.


    Anaerobic Procedure** for Lactic Acid Bacteria Testing

    • The 3M™ Petrifilm™ Aerobic Count Plate enumerates total aerobic bacteria present in the sample tested. Following a simple protocol they can also be used for enumerating anaerobic bacteria for processed meats and in high acid foods.

      Fast, accurate, results in 48 hours with three easy steps:

      1. Inoculate - 3M™ Petrifilm™ Plates are easy to inoculate. Lift the top film and add sample.

      2. Incubate - The space saving design maximizes incubator space.

      3. Enumerate - A red indicator dye in the plate colors all colonies red. This 3M Petrifilm Plate can also be read in 4 seconds using the 3M™ Petrifilm™ Plate Reader.

      The unique construction of the 3M Petrifilm Aerobic Count Plates makes it possible to distinguish gas-producing heterofermentative organisms from non-gas-producing homofermenters. The addition of MRS broth to 3M Petrifilm Aerobic Count Plates, in combination with anaerobic incubation enhances the growth of lactobacilli and other lactic acid bacteria in high acid/high products and processed meat products.

    The 3M™ Petrifilm™ Aerobic Count Plate is a time-saving, sample-ready plate designed to determine total aerobic bacteria populations.

    A built-in grid facilitates counting colonies, helping to provide fast, precise and consistent results. Each 3M Petrifilm Aerobic Count Plate contains a water-soluble gelling agent, nutrients and indicator — all the components needed for microbial growth with no agar preparation required.

    The 3M Petrifilm Aerobic Count Plate provides total aerobic count in as little as 48 hours. A red indicator dye in the plate colors all colonies red for better contrast and easier colony counting. The red colonies are also easily distinguished from opaque food particles that can cause confusion when using other plating methods.

    In addition, 3M Petrifilm Aerobic Count Plates can be used to aerobically or anaerobically enumerate lactic acid bacteria in food and environmental samples.

    Three Easy Steps Offer Fast, Easy-to-Interpret Results:*

    • 1) Inoculate - 3M Petrifilm Aerobic Count Plates are easy to inoculate. Lift the top film and add sample.
    • 2) Incubate - The space saving design minimizes incubator space requirements.
    • 3) Interpret - Count the red colonies; a built-in grid simplifies counting, giving you fast, precise, and consistent results.
    • *Refer to instructions for use for additional information, and more details on validations.

      This 3M Petrifilm Aerobic Count Plate can also be read using the 3M™ Petrifilm™ Plate Reader. This plate reader provides consistent, fast, automated reading and recording of results of 3M Petrifilm Plates (Aerobic Count, Coliform Count and E. coli/Coliform Count) in 4 seconds.
