DOI: 10.1021/acs.biochem.1c00605
Abstract: Biofilms are communities of self-enmeshed bacteria in a matrix of exopolysaccharides. The widely distributed human pathogen and commensal Escherichia coli produces a biofilm matrix composed of phosphoethanolamine (pEtN)-modified cellulose and amyloid protein fibers, termed curli.… read more here.

DOI: 10.1021/acs.est.9b02865
Abstract: Biofilms, composed of periphyton, bacteria and organic detritus, are the base of the food web in many streams and rivers. This media adsorbs and actively sequesters organic and inorganic contaminants from the water column. Here,… read more here.

DOI: 10.1128/mbio.00543-18
Abstract: ABSTRACT Pseudomonas aeruginosa produces an extracellular biofilm matrix that consists of nucleic acids, exopolysaccharides, lipid vesicles, and proteins. In general, the protein component of the biofilm matrix is poorly defined and understudied relative to the… read more here.

DOI: 10.1128/mbio.01376-18
Abstract: Pseudomonas aeruginosa forms multicellular aggregates or biofilms using both exopolysaccharides and the CdrA matrix adhesin. We showed for the first time that P. aeruginosa can use CdrA to build biofilms that do not require known… read more here.

DOI: 10.1371/journal.pgen.1008232
Abstract: In nature, most bacteria live in biofilms where they compete with their siblings and other species for space and nutrients. Some bacteria produce antibiotics in biofilms; however, since the diffusion of antibiotics is generally hindered… read more here.

DOI: 10.3389/fmicb.2019.00677
Abstract: Most microbes can produce surface-associated or suspended aggregates called biofilms, which are encased within a biopolymer-rich matrix. The biofilm matrix provides structural integrity to the aggregates and shields the resident cells against environmental stressors, including… read more here.
