The formation of a biofilm on the surface involves very complex and diverse events,among which attachment is the most important aspect of biofilm formation.The complex modification of bacteriophages from planktonic to biofilm means that biofilms can tolerate various external stressors by agglomerating with one another [ 1 ].Periodicities in the roughness and biofilm growth on glass Mar 27,2019 Physicochemical regulation of biofilm formation MRS#0183;Adherence of the microorganism to submerged solid surfaces leads to biofilm formation.Biofilm formation modifies the surfaces in favor of bacteria facilitating the survival of the bacteria under different stressed conditions.On the other hand,the formation of biofilm has a direct adverse economic impact in various industries and more importantly in medical practices.NanoparticleBiofilm Interactions The Role of the EPS The negative consequences of biofilms are widely reported.A defining feature of biofilms is the extracellular matrix,a complex mixture of biomacromolecules,termed EPS,which contributes to reduced antimicrobial susceptibility.EPS targeting is a promising,but underexploited,approach to biofilm control allowing disruption of the matrix and thereby increasing the susceptibility to

The biofilms are multispecies communities fixed to a surface and producing extra poylmeric substances which encapsulate the cells.The biofilm can be considered as a balance between a planktonic and a biofilm phase.Researches about the interaction and cells communications are important to fully understand all the mechanisms taking place in this system.For the controlled growth of repeatable Cited by 371Publish Year 2011Author Lars D.Renner,Douglas B.WeibelPhysicochemical regulation of biofilm formationIn this review,we have summarized the physicochemical factors that govern the initial attachment and adhesion of bacteria to surfaces,which is the first step in biofilm formation.The general rule-of-thumb is that bacteria will preferentially colonize surfaces that are hydrophobic,have surface roughness on the nano- and microscale,and are exposed to a conditioning layer in contrast to smooth,hydrophilicCited by 371Publish Year 2011Author Lars D.Renner,Douglas B.WeibelPhysicochemical regulation of biofilm formation.(1) Physical properties of surfaces regulate cell attachment and physiology and affect early stages of biofilm formation.(2) Chemical properties influence the adhesion of cells to surfaces and their development into biofilms and communities.(3) Chemical communication between cells attenuates growth and influences the organization of communities.
