WebBiofilm formation is an important biological concept in environmental microbiology, wherein the microbial cells adapt to multicellular lifestyle by formation of biofilm during which the bacterial cells are self-immobilized in extracellular polymeric matrix. WebThus, the area of surface modification to prevent biofilm formation is a large field, and many comprehensive reviews on this topic already exist (Katsikogianni and Missirlis, 2004; Arciola et al., 2012; Bazaka et al., 2012; Campoccia et al., 2013). The use of small molecule biofilm inhibitors is another approach used to prevent biofilm formation.
WebA biofilm is an architectural colony of microorganisms, within a matrix of extracellular polymeric substance that they produce. Biofilm contains microbial cells adherent to one-another and to a static surface (living or non-living). Bacterial biofilms are usually pathogenic in nature and can cause nosocomial infections. WebStages of Biofilm Formation The growth and development of biofilm are characterized by 4 stages: initial adherence, lag phase, rapid growth, and steady state. Biofilm formation begins with the adherence of bacteria to a tooth surf ace, followed by a lag phase in which changes in genetic expression (phenotypic shifts)occur.
WebThe final stage of biofilm formation is known as dispersion, and is the stage in which the biofilm is established and may only change in shape and size.
