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. [8] Biofilms can form on the teeth of most animals as dental plaque, where they may cause tooth decay and gum disease.
There has been a great effort to develop efficient methods for biofilm removal or prevention in clinical and food manufacturing processes. On the other hand, current research suggested that biofilms can be useful for constructive purposes such as a template of new materials [1] [2] that may find applications in the industry. One distinctive ...
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. EPS will colonize the cells at the surface with hydrogen bonding.
[1] [2] Particularly, in the ever-changing environments of intertidal systems, biofilms can facilitate a range of microbial processes and create protective microenvironments where cells communicate with each other and regulate further biofilm formation via Quorum Sensing (QS).
Phototrophic biofilms are microbial communities generally comprising both phototrophic microorganisms, which use light as their energy source, and chemoheterotrophs. [1] Thick laminated multilayered phototrophic biofilms are usually referred to as microbial mats or phototrophic mats (see also biofilm ). [ 2 ]
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.
UVC irradiation is a noncontact, nonchemical solution that can be used across a range of instruments. Radiation in the UVC range prevents biofilm formation by deactivating the DNA in bacteria, viruses, and other microbes. Preventing biofilm formation prevents larger organisms from attaching themselves to the instrument and eventually rendering ...
For example, oxidization is a common cause of corrosion. If a susceptible surface has a biofilm covering it that takes in and uses oxygen, then that surface will be protected from corrosion due to oxidization. Biofilms can also release antimicrobial compounds, which is helpful if the biofilm is not corrosive and can deter microbes that would be.
