Microbial Mat Definition

These are rocky mounds built up over time as mats trap and interact with sediment.

Microbial mat definition. Microbial mats as a study model is an easily accessible viable laboratory and these communities present with varying degrees of complexity from simple non phototrophic mats ynp mats with a low diversity of phototrophs to the complex hypersaline and mats obtained from guerrero negro méxico and llamará chile. Microbial mats play an important role in forming geological features known as stromatolites. Stromatolites can be found in environments like guerrero negro today but these structures also appear in the geologic record of the earth. A few are found as endosymbionts of animals.

Microbial mats are often centimeter thick multilayered structures of microorganisms mainly bacteria archaea fungi and sometimes these mats are enriched with protozoans. Microbial mats are laminated microbial communities that generally develop in aqueous environments under conditions that exclude fauna. Microbial biofilms are in contrast much thinner 10 100 µm than microbial mats and have a different architecture characklis and wilderer 1989. Microbial mats can be considered a specialized type of biofilm.

Biofilms can form on the teeth of most animals as dental plaque where they may cause tooth decay and gum disease. A microbial mat is a multi layered sheet of microorganisms mainly bacteria and archaea and also just bacterial microbial mats grow at interfaces between different types of material mostly on submerged or moist surfaces but a few survive in deserts. While biofilms are typically one to several cell layers thick microbial mats range from several millimeters to a centimeter thick and are vertically stratified into. In fact ancient stromatolite.

A unicellular or small multicellular organism including bacteria protozoa some algae and fungi viruses and some worms esp. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism which by contrast are single cells that may float or swim in a liquid medium.

The biogeochemical cycles in microbial mats are usually largely closed although small fluxes of elements are exchanged with the geo bio and atmosphere. A spelling or a grammatical mistake.
