Pseudomonas aeruginosa rhamnolipids disperse Bordetella bronchiseptica biofilms.
We have previously reported that the respiratory pathogen Bordetella bronchiseptica can form biofilms in vitro. In this report, we demonstrate the disruption of B. bronchiseptica biofilms by rhamnolipids secreted from Pseudomonas aeruginosa. This suggests that biosurfactants such as rhamnolipids may be utilized as antimicrobial agents for removing Bordetella biofilms.
متن کاملEnzymatic detachment of Staphylococcus epidermidis biofilms.
The gram-positive bacterium Staphylococcus epidermidis is the most common cause of infections associated with catheters and other indwelling medical devices. S. epidermidis produces an extracellular slime that enables it to form adherent biofilms on plastic surfaces. We found that a biofilm-releasing enzyme produced by the gram-negative periodontal pathogen Actinobacillus actinomycetemcomitans ...
متن کاملShear-induced detachment of biofilms from hollow fiber silicone membranes.
A suite of techniques was utilized to evaluate the correlation between biofilm physiology, fluid-induced shear stress, and detachment in hollow fiber membrane aerated bioreactors. Two monoculture species biofilms were grown on silicone fibers in a hollow fiber membrane aerated bioreactors (HfMBR) to assess detachment under laminar fluid flow conditions. Both physiology (biofilm thickness and ro...
متن کاملA computer investigation of chemically mediated detachment in bacterial biofilms.
A three-dimensional computer model was used to evaluate the effect of chemically mediated detachment on biofilm development in a negligible-shear environment. The model, BacLAB, combines conventional diffusion-reaction equations for chemicals with a cellular automata algorithm to simulate bacterial growth, movement and detachment. BacLAB simulates the life cycle of a bacterial biofilm from its ...
متن کاملAmyloids-DNA complexes mediate adherence and cohesiveness of bacterial biofilms
Complexity of bacterial biofilms is generally due to their composition in terms of microorganisms as well as in the diversity of their matrix components. The commonly described extracellular polymeric substances (EPS) are exopolysaccharides (ePS), exoproteins (ePN) and extracellular DNA (eDNA). Besides, several studies have shown that the ePN are the most abundant compound within a biofilm [1]....
