How biofilms work

WebBiofilm formation process is species-dependent and complicated but can be basically divided into five main stages: (1) the floating cells attach to the substrates through adsorption to form a reversible conditioning film; (2) irreversible adhesion begins due to the secretion of EPS, which colonize the cells to the surface via hydrogen bonding; … WebBiofilms are the perfect playground for the bacteria to feed and grow into larger and more dangerous quantities. Reducing the presence of biofilms within a water system will lead to a reduced risk of legionella, pseudomonas and other bacteria growing to dangerous levels that may cause harm.
