Simple heterocycles to inhibit fungi and bacterial biofilm formation

Categories

Cleantech, Environment, Water Technologies, Biofouling, Biofilm, Food Packaging

Development Stage

Our technology has been proven to reduce up to 60% biofilm after one coating application on pipes' inner surfaces, in the Israeli main recycling water center (SAFDAN)

Patent Status

Patent applications filed in the US (2011-0281921-A1)and Europe (2365969)

Market Size

The total market for anti fouling solutions is estimated in billions of dollars annually

Highlights

  • Simple heterocyclic compounds disrupt cell–cell communication (quorum sensing) interfering with the formation of biofilms
  • First compounds to exhibit cross kingdom inhibition and reversal of biofilms
  • Environmentally friendly method to control the formation of biofilms on artificial surfaces such as water pipes or air-conditioning ducts in industry and agriculture
  • Non-leaching polymer coatings

Our Innovation

  • Novel simple heterocyclic compounds, synthesized to resemble the structure of the natural auto inducer-2, are used as polymer coatings for water pipes, membranes, food packaging and other surfaces to disrupt quorum sensing between bacterial cells and prevent the formation of biofilms.

 

Key Features

  • No antibacterial or antifungal effect, avoids development of resistant strains
  • Environmentally safe – non-leaching coating
  • Effective against both fungal and bacterial biofilms
  • Inhibit and reverse biofilm formation

Development Milestones

  • Additional compounds to be synthesized
  • Additional field trials in agricultural, municipal and industrial water pipes, homes and hospitals

The Opportunity

  • Biofilm-related problems cost U.S. industry billions of dollars annually by corroding pipes, reducing heat transfer or hydraulic pressure in industrial cooling systems, plugging water injection jets, and clogging water filters.
  • Applications include industrial water treatment, prevention of biofilm formation on filtration membranes, paints and coatings, irrigation pipelines, paper-making machines, food packaging
  • Cost of desalination and water recycling processes reduced by lowering energy consumption
