These microbes will produce a slime coat which also has an appropriate ionic charge to attract more nitrifiers on the surface on the media. When storing used media, it would be beneficial to store it in a dark cold room at 4C because some beneficial heterotrophic bacteria can go dormant. It is these heterotrophic bacteria that produce these sticky sugars. Some of these heterotrophic bacteria sporulate. Nitrifiers does not.
Abit more technical than I am going to say...
What do you need to eat to be healthy? Exactly what you are made of... Freeze dried human is nutritious. Same thing for bioifilm, and it has no qualms about munching down on a relative. Wet or dried.
