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.
The image shows the location, in the Burgsvik beds of Sweden, where the texture was first identified as evidence of a microbial mat. [ 1 ] Microbially induced sedimentary structures (MISS) are primary sedimentary structures formed by the interaction of microbes with sediment and physical agents of erosion, deposition, and transportation.
Phototrophic biofilms and microbial mats have been described in extreme environments like thermal springs, [3] hyper saline ponds, [4] desert soil crusts, and in lake ice covers in Antarctica. The 3.4-billion-year fossil record of benthic phototrophic communities, such as microbial mats and stromatolites , indicates that these associations ...
The organic component is an elaborate microbial mat where different communities of microorganisms interact according to different metabolisms and create a micro-niche where oxygenic and anoxygenic phototrophic organisms coexist: nitrogen fixers, sulfur reducers, methaneotrophs, methanogens, iron oxidizers, and an infinity of heterotrophic ...
In modern microbial mats, debris from the surrounding habitat can become trapped within the polysaccharide layer, which can be cemented together by the calcium carbonate to grow thin laminations of limestone. These laminations can accrete over time, resulting in the banded pattern common to stromatolites.
Contamination control is the generic term for all activities aiming to control the existence, growth and proliferation of contamination in certain areas. Contamination control may refer to the atmosphere as well as to surfaces, to particulate matter as well as to microbes and to contamination prevention as well as to decontamination.
Not unlike your bacteria-covered bath mat, your dish drying mat is totally gross. It’s true. It’s true. Just because your dishes are freshly-washed doesn’t mean bacteria isn’t lurking.
Sewage fungus is a type of microbial mat, the specific composition of which is affected by the available nutrients (especially organic carbon sources) and the environmental drivers of each unique occurrence. However, several key taxa are reported as highly frequent and dominant within sewage fungus.
