Biofilm growth is associated with an escalated level of mutations and horizontal gene transfer which is promoted in due to the packed and dense structure. Bacteria in biofilms communicate by quorum sensing, which activates genes participating in virulence factors production. [25] [26] Biofilms are the product of a microbial developmental ...
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 ]
Rather, a biofilm is made up of an array of microorganisms that come together to form a cohesive biofilm. [7] Although, there are homogeneous biofilms that can form. For example, the plaque that forms on the surfaces of teeth is caused by a biofilm formation of primarily Streptococcus mutans and the slow breakdown of tooth enamel. [8] [9]
The formation of biofilms is a complex process and is dependent upon the availability of light as well as the relationships between the microorganisms. Biofilms serve a variety of roles in aquatic, terrestrial, and extreme environments; these roles include functions which are both beneficial and detrimental to the environment.
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.

Stromatolites are layered, biochemical, accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), through the action of certain microbial lifeforms, especially cyanobacteria. [12]
