  2. Biofilm - Wikipedia

    en.wikipedia.org/wiki/Biofilm

    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.

  3. Biofilm prevention - Wikipedia

    en.wikipedia.org/wiki/Biofilm_prevention

    The ability of bacteria to adhere to a surface and begin the formation of a biofilm is determined in part by the enthalpy of adhesion of the surface. Adherence is thermodynamically favored if the free enthalpy of adhesion is negative and decreases with increasing free enthalpy values. [ 7 ]

  4. Quorum sensing - Wikipedia

    en.wikipedia.org/wiki/Quorum_sensing

    Quorum sensing (QS) is used by bacteria to form biofilms. Quorum sensing is used by bacteria to form biofilms because the process determines if the minimum number of bacteria necessary for biofilm formation are present. The criteria to form a biofilm is dependent on a certain density of bacteria rather than a certain number of bacteria being ...

  5. Extracellular polymeric substance - Wikipedia

    en.wikipedia.org/wiki/Extracellular_polymeric...

    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.

  6. Dental plaque - Wikipedia

    en.wikipedia.org/wiki/Dental_plaque

    The bacterial equilibrium position varies at different stages of formation. Below is a summary of the bacteria that may be present during the phases of plaque maturation: Early biofilm: primarily Gram-positive cocci; Older biofilm (3–4 days): increased numbers of filaments and fusiforms

  7. Phototrophic biofilm - Wikipedia

    en.wikipedia.org/wiki/Phototrophic_biofilm

    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.

  8. Tooth decay - Wikipedia

    en.wikipedia.org/wiki/Tooth_decay

    The development of biofilm begins with pellicle formation. Pellicle is an acellular proteinaceous film which covers the teeth. Bacteria colonize on the teeth by adhering to the pellicle-coated surface. Over time, a mature biofilm is formed, creating a cariogenic environment on the tooth surface.

  9. Curli - Wikipedia

    en.wikipedia.org/wiki/Curli

    Probiotic-associated therapeutic curli hybrids (PATCH) [1] The Curli protein is a type of amyloid fiber produced by certain strains of enterobacteria.They are extracellular fibers located on bacteria such as E. coli and Salmonella spp. [2] These fibers serve to promote cell community behavior through biofilm formation in the extracellular matrix.
