The formation of a biofilm begins with the attachment of free-floating microorganisms to a surface. [ 8 ] [ 5 ] The first colonist bacteria of a biofilm may adhere to the surface initially by the weak van der Waals forces and hydrophobic effects.
Biofilm formation occurs when free floating microorganisms attach themselves to a surface. Although there are some beneficial uses of biofilms , they are generally considered undesirable, and means of biofilm prevention have been developed.
Biofilm formation begins with the initial attachment of microorganisms to a substrate, such as rocks, shells, or sand in the intertidal zone. This process occurs during the reversible attachment phase, in which the microorganisms only lightly adhere to the substrate. [5]
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]
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.
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.

According to some estimates, over 1,700 species comprising over 4,000 organisms are responsible for biofouling. [7] Biofouling is divided into microfouling—biofilm formation and bacterial adhesion—and macrofouling—attachment of larger organisms. Due to the distinct chemistry and biology that determine what prevents them from settling ...
