Gluey polymers secreted by microorganisms to form biofilms
Extracellular polymeric substance matrix formation in a biofilm
Extracellular polymeric substances (EPSs) are natural polymers of high molecular weight secreted by microorganisms into their environment.[1] EPSs establish the functional and structural integrity of biofilms, and are considered the fundamental component that determines the physicochemical properties of a biofilm.[2] EPS in the matrix of biofilms provides compositional support and protection of microbial communities from the harsh environments.[3] Components of EPS can be of different classes of polysaccharides, lipids, nucleic acids, proteins, lipopolysaccharides, and minerals. This chemical formula is (C135H217N15Na2O74P10).
