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 biofilm is a syntrophic community of microorganisms in which cells stick to each other and often also to a surface. [2] [3] These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPSs).
EPS is found in the matrix of other microbial biofilms such as microalgal biofilms. The formation of biofilm and structure of EPS share a lot of similarities with bacterial ones. The formation of biofilm starts with reversible absorption of floating cells to the surface. Followed by production of EPS, the adsorption will get irreversible.
Outer membrane proteins are membrane proteins with key roles associated with bacterial cell structure and morphology; cell membrane homeostasis; the uptake of nutrients; protection of the cell from toxins including antibiotics; and virulence factors including adhesins, exotoxins, and biofilm formation.
Biofilms in marine environments Various biofilm components (including bacteria, algae, and fungi) are embedded in a matrix of extracellular polymeric substances.. An intertidal bioflim is a biofilm that forms on the intertidal region of bodies of water.
