Biofilm Disruption Strategies: Combatting Microbial Biofilms

Biofilm Disruption involves the removal or prevention of biofilms, which are microbial communities that adhere to surfaces and can cause infections and product contamination.

How is biofilm disruption achieved?

Biofilm disruption is achieved via matrix degrading enzymes such as nucleases that can degrade extracellular DNA [ 28] and proteases that degrade scaffold proteins and polysaccharides [ 29 ]. EPS targeting therapies for biofilm disruption in development are reviewed elsewhere [ 30•• ].

Can biofilm dispersion help combat biofilm-related infections?

Biofilms are extremely difficult to eradicate due to their decreased antibiotic susceptibility. Inducing biofilm dispersion could be a potential strategy to help combat biofilm-related infections. Mechanisms of biofilm dispersion can basically be divided into two groups, i.e. active and passive dispersion.

How do biofilm remediation strategies work?

Currently, most biofilm remediation strategies involve the development of biofilm-inhibition agents, aimed at preventing the early stages of biofilm formation, or biofilm-dispersal agents, aimed at disrupting the biofilm cell community.

What are the mechanisms of biofilm dispersion?

Mechanisms of biofilm dispersion can basically be divided into two groups, i.e. active and passive dispersion. Active dispersion depends on a decrease in the intracellular c-di-GMP levels, leading to the production of enzymes that degrade the biofilm matrix and promote dispersion.

What is the mechanism of biofilm formation and dispersion?

Biofilm formation and dispersion. a In the mechanism of biofilm formation, the two-component system is usually composed of sensor kinases and response regulators. Quorum sensing includes AHL-based quorum sensing systems and PQS-based quorum sensing systems.

How can biofilm formation be prevented?

Growing strategies that have been developed to combat biofilm formation include targeting bacterial enzymes, as well as those involved in the quorum sensing and adhesion pathways.

Which enzyme classes are involved in biofilm disruption?

Herein, we review the recent progress of biofilm disruption via three major enzyme classes: glycoside hydrolases 44, 45, deoxyribonucleases 46, 47, and proteases 48, 49. As the major component of the EPS, secreted extracellular polysaccharides are critical for biofilm integrity.
