Cohesiveness in biofilm matrix polymers
WebDec 1, 2005 · A kinetic model is proposed to assess the feasibility of strategies for the removal of biofilms by using substances that induce detachment by affecting the cohesiveness of the matrix of extracellular polymeric substances (EPSs). The model uses a two-state description of the EPS (natural EPS and compromised EPS) to provide a … WebBiofilm formation occurs when free floating microorganisms attach themselves to a surface. Although there are some beneficial uses of biofilms, they are generally considered undesirable, and means of biofilm prevention have been developed. Biofilms secrete extracellular polymeric substance that provides a structural matrix and facilitates …

WebNov 17, 2024 · 1 Introduction. Biofilms form a heterogeneous matrix consisting of microbial communities and their secreted extracellular polymeric substances (EPSs) (Wingender et al., 1999) and in sediments incorporate particles within the matrix.Microorganisms that inhabit sediments and form biofilms are highly adapted for this habitat and secrete … WebAug 1, 2024 · Biofilm is defined as a structured community of microbial cells firmly attached to a surface and embedded in a matrix composed of extracellular polymeric substances ( EPS) (see Glossary). The EPS consist of exopolysaccharides, nucleic acids (eDNA and eRNA [ 1 ]), proteins, lipids, and other biomolecules.
WebConsiderable variation in biofilm phenotype was observed, including waxy aggregations, viscous and floccular masses, and physically cohesive biofilms with continuously varying strengths over 1500-fold. WebMost of the existing sediment transport behaviour was described mostly based on non-cohesive sediment, whereas studies on the influence of physical cohesion have also been picked up [Citation 9, Citation 10].Additional binding of biological cohesion (through EPS) significantly changes the bedform development compared to the abiotic-influenced …
