Web15 de mai. de 2024 · Biofilms are thus very different from what we call “planktonic cultures.” These consist of isolated bacteria freely swimming in a liquid, like plankton in the sea. In the environment, biofilms form everywhere: on pipelines, boat hulls, rocks, or … WebTo form biofilms, planktonic cells must first reach the substratum to which they attach. Motile microorganisms can use structures such as flagella to seek out the surface, guided by chemotactic, aerotactic, or phototactic responses. Motility promotes both initial interaction with the surface and movement along it.
