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).
Using biofilms that are grown intentionally to inhibit microbial corrosion. This is done by growing a biofilm on a surface made of a bacteria that can release compounds that kill other microbes and that prevent corrosion. Using essential oils. The effectiveness of essential oils against microbial corrosion has not been widely tested.
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.
The C2DA inhibit methicillin resistant staphylococcus biofilm, but don't eliminate it. The mechanism of the biofilm inhibition by these molecules is still unknown. C2D is a medium of fatty acid chain that effect on staphylococcus aureus biofilm and dispersion of these biofilm. Pseudomonas aeruginosa is the main source for these molecules. [15]
Common approaches to treating bioclogging include utilizing phosphate, a critical nutrient for iron-bacteria biofilms, and employing chlorine and fungicides to address bacterial issues. Backwashing is a common method to deal with clogging in general, including bioclogging.
Biofilms can consist of a multitude of bacteria, fungi, and algae which are able to absorb, immobilize, and degrade many common pollutants found in wastewater.By harnessing a natural phenomenon, biofilm-mediated remediation is an environmentally friendly method for environmental cleanup. [3]
Biofilms, which are biological growths that become attached to the discs, assimilate the organic materials (measured as BOD5) in the wastewater. Aeration is provided by the rotating action, which exposes the media to the air after contacting them with the wastewater, facilitating the degradation of the pollutants being removed.
The most commonly recognised bacteria that are responsible for initiating the biofilm formation that can eventually lead to caries are streptococcus mutans and lactobacillus. [15] The key factors for virulence include their ability to metabolise glucose and similar sugars, their tolerance for a low pH environment, and their acidogenicity. [ 16 ]
