Don’t Break the Biofilm. Open It.

• Biofilms are organised communities of bacteria encased in a protective, slimy matrix.

• They're nature's most effective survival tactic—making bacteria up to 1,000 times more resistant to antibiotics and disinfectants than their free-floating counterparts.

The Hidden Threat Right Under Our Eyes

• Biofilms are everywhere: coating ship hulls beneath the waves, forming inside medical catheters, clogging industrial pipes, and even creating the plaque on your teeth. What appears as a simple "slimy layer" is actually a sophisticated bacterial city with organised neighbourhoods, communication networks, and defence systems.

How Biofilms Form and Persist

• Bacteria don't simply stick to surfaces randomly—they undergo a detailed multi-step process.

• Attachment: Individual bacteria land on a surface and begin to adhere.

• Maturation: Complex 3D structures develop, featuring channels for nutrient flow and a slimy, impermeable covering called the EPS.

• Dispersal: Some bacteria detach to colonise new surfaces or leave due to low nutrients.

• The EPS, composed of proteins, DNA, lipids, polysaccharides, metals, and water, functions like a fortress wall, blocking antibiotics and immune cells from reaching the bacteria inside. This is why biofilm infections are so stubborn and difficult to treat.

Biofilms represent one of the most pressing challenges across healthcare, industry, and environmental systems. Their ability to resist conventional treatments makes them a $100+ billion global problem that demands innovative solutions.

🏥 Healthcare Crisis

Chronic Wounds & Infections: Up to 80% of chronic wounds contain biofilms that prevent healing. Hospital-acquired infections often involve biofilm-forming bacteria on medical devices.

Antibiotic Failure: Standard treatments fail because antibiotics can't penetrate the biofilm matrix, leading to recurring infections and the development of antibiotic-resistant superbugs.

🚢 Marine & Industrial Impact

Economic Costs: Marine biofouling raises ship fuel use by 20-40%, significantly adding to global carbon emissions and operating expenses.

Infrastructure Damage: Biofilms cause "microbiologically influenced corrosion" in pipelines, water systems, and industrial equipment, leading to billions in maintenance and replacement costs.

🌍 Environmental Challenges

Water Treatment: Biofilms in water treatment facilities can shelter pathogens and decrease system efficiency, threatening public health and leading to costly cleaning procedures.

Food Safety: Persistent biofilms on food processing equipment can be sources of contamination, leading to foodborne illness outbreaks despite regular cleaning procedures.

The Treatment Gap

Current approaches have significant limitations:

• Chemical biocides: Often harmful to the environment and can encourage resistance

• Physical Removal: Labour-intensive, temporary, and often incomplete

• High-Dose Antibiotics: Can lead to serious side effects and promote resistance

• UV/Heat Treatment: Not suitable for many applications, especially living systems

The Need for Innovation: We need solutions that work with biology, not against it—approaches that can disrupt biofilms without harming surrounding tissues, the environment, or beneficial microorganisms.

Inspiration from Marine Environments

Our research started with a simple observation: despite constant exposure to bacteria, some marine species’ surfaces stay surprisingly clean. This made us wonder, HOW?

We found that materials frequently thrown away as seafood waste contain bioactive compounds that can impact bacterial communities—particularly their capacity to form and maintain protective biofilms.

A Different Approach: Working with Natural Mechanisms

Instead of trying to kill bacteria, our compounds appear to work alongside natural bacterial communication systems. To explore this further, we have developed a new in-situ bioassay model using marine algae that allows real-time visual observation of changes in biofilm behaviour, such as:

• Significant changes in biofilm structure

• Natural activation of the dispersal mechanism

• No direct antimicrobial effects

• Sustainable waste transformation

This in-situ model clearly demonstrates how our seafood-derived compounds influence existing biofilm communities without harming the bacteria themselves.

The system’s transparency allows us to record real-time changes, offering clear visual evidence of this innovative approach.

• We’ve discovered bioactive compounds from seafood processing waste that show promising anti-biofilm properties. This breakthrough provides a new method for converting marine waste streams into valuable biofilm-control solutions.

• A Different Approach: Engaging with Natural Processes

  Instead of trying to kill bacteria—which often fails and can promote resistance—our compounds appear to work alongside natural bacterial communication systems. We have created a new in situ bioassay model using marine algae that allows real-time visual tracking of changes in biofilm behaviour.

  In our laboratory studies using this innovative viewing system, we have observed:

• Significant - Biofilm structural changes

• Natural - Activation of dispersal mechanism

• No - Direct antimicrobial effects.

• Sustainable - Waste conversion

• This in-situ model clearly shows that our seafood-derived compounds influence existing biofilm communities, triggering what seem to be natural release and restructuring processes without harming the bacteria themselves.
