  2. Biofilm - Wikipedia

    en.wikipedia.org/wiki/Biofilm

    Research suggests that biofilm formation by S. marcescens is a process controlled by both nutrient cues and the quorum-sensing system. [127] Quorum sensing influences the bacterium's ability to adhere to surfaces and establish mature biofilms, whereas the availability of specific nutrients can enhance or inhibit biofilm development.

  3. Phototrophic biofilm - Wikipedia

    en.wikipedia.org/wiki/Phototrophic_biofilm

    Biofilm formation is a complicated process which occurs in four general steps: attachment of cells, formation of the colony, maturation, and cell dispersal. These films can grow in sizes ranging from microns to centimeters in thickness.

  4. Dental plaque - Wikipedia

    en.wikipedia.org/wiki/Dental_plaque

    Dental plaque is a biofilm that attaches to tooth surfaces, restorations and prosthetic appliances (including dentures and bridges) if left undisturbed.Understanding the formation, composition and characteristics of plaque helps in its control. [6]

  5. Intertidal biofilm - Wikipedia

    en.wikipedia.org/wiki/Intertidal_biofilm

    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]

  6. Candida albicans - Wikipedia

    en.wikipedia.org/wiki/Candida_albicans

    The biofilm of C. albicans is formed in four steps. First, there is the initial adherence step, where the yeast-form cells adhere to the substrate. The second step is called Intermediate step, where the cells propagate to form microcolonies, and germ tubes form to yield hyphae. In the maturation step, the biofilm biomass expands, the ...

  7. Slow sand filter - Wikipedia

    en.wikipedia.org/wiki/Slow_sand_filter

    Slow sand filters work through the formation of a gelatinous layer (or biofilm) called the hypogeal layer or Schmutzdecke in the top few millimetres of the fine sand layer. The Schmutzdecke is formed in the first 10–20 days of operation [ 9 ] and consists of bacteria , fungi , protozoa , rotifera and a range of aquatic insect larvae.

  8. Microbial mat - Wikipedia

    en.wikipedia.org/wiki/Microbial_mat

    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.

  9. Virulence factor - Wikipedia

    en.wikipedia.org/wiki/Virulence_factor

    The cytolytic peptide Candidalysin is produced during hyphal formation by Candida albicans; it is an example of a virulence factor from a fungus. Other virulence factors include factors required for biofilm formation (e.g. sortases) and integrins (e.g. beta-1 and 3). [7]
