Journal ArticleDOI
Pel is a cationic exopolysaccharide that cross-links extracellular DNA in the Pseudomonas aeruginosa biofilm matrix

TL;DR: A tool for the direct visualization of Pel in biofilms is developed by combining Pel-specific Wisteria floribunda lectin staining with confocal microscopy and the results indicate that Pel cross-links eDNA in the biofilm stalk via ionic interactions.
Journal ArticleDOI
Chemical Analysis of Cellular and Extracellular Carbohydrates of a Biofilm-Forming Strain Pseudomonas aeruginosa PA14
TL;DR: It is shown that the extracellular matrix of the thick biofilm formed at the A-L interface contained, in addition to eDNA, important quantities of LPS-like material, which is found as a component of a biofilm matrix of P. aeruginosa.
Journal ArticleDOI
Preliminary Characterizations of a Carbohydrate from the Concentrated Culture Filtrate from Fusarium solani and Its Role in Benzo[a]Pyrene Solubilization
TL;DR: The findings point out the potential role of fungal glycoproteins in PAH microbial bioavaibility, an important step for PAH biodegradation.
Journal ArticleDOI
Stress-Induced Dispersal of Staphylococcus epidermidis Biofilm Is Due to Compositional Changes in Its Biofilm Matrix
Charlène Coulon,Irina Sadovskaya,Philippe Lencel,Saïd Jabbouri,Jeffrey B. Kaplan,Sigrid Flahaut +5 more
TL;DR: It is found that oligotrophic stress led to rapid dispersal of pre-formed biofilms and concomitant changes in the composition of the extracellular matrix, including a decrease in poly-N-acetylglucosamine polysaccharide and an increase in proteins.
