A biofilm is a syntrophic community of microorganisms in which cells stick to each other and often also to a surface. [2] [3] ...
The acid is produced by the bacteria when they break down food debris or sugar on the tooth surface. [4] Simple sugars in food are these bacteria's primary energy source and thus a diet high in simple sugar is a risk factor. [4] If mineral breakdown is greater than buildup from sources such as saliva, caries results. [4]
Supragingival biofilm is dental plaque that forms above the gums, and is the first kind of plaque to form after the brushing of the teeth. It commonly forms in between the teeth, in the pits and grooves of the teeth and along the gums. It is made up of mostly aerobic bacteria, meaning these bacteria need oxygen to survive.
The air flows through a packed bed and the pollutant transfers into a thin biofilm on the surface of the packing material. Microorganisms, including bacteria and fungi are immobilized in the biofilm and degrade the pollutant. Trickling filters and bioscrubbers rely on a biofilm and the bacterial action in their recirculating waters.
Biofilms. Bacteria often attach to surfaces and form dense aggregations called biofilms [ 51 ] and larger formations known as microbial mats . [ 52 ] These biofilms and mats can range from a few micrometres in thickness to up to half a metre in depth, and may contain multiple species of bacteria, protists and archaea.

A microbial mat is a multi-layered sheet or biofilm of microbial colonies, composed of mainly bacteria and/or archaea. Microbial mats grow at interfaces between different types of material, mostly on submerged or moist surfaces, but a few survive in deserts. [1] A few are found as endosymbionts of animals.
