How To Use Petrifilm Aerobic Count Plates Youtube With petrifilm plates, there are just three simple steps; inoculate, incubate, and interpret.start by removing the ready to use petrifilm aerobic count plate. The 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.
