Bye Bye, Bacteria And Fungi!

BiofilmYissum, the technology transfer arm of the Hebrew University of Jerusalem, introduced a novel method for preventing and affecting biofilm of bacteria and fungi at the WATEC Conference, held in Tel Aviv, Israel on November 17-19, 2009. The invention, developed jointly by the Hadassah Medical Organization and Hebrew University of Jerusalem (the Faculty of Dental Medicine and the Institute of Drug Research), utilizes novel heterocyclic compounds that disrupt cell-cell communication, thereby interfering with the formation of biofilms. Unlike the use of antibiotics which often induce formation of resistant strains, the compounds do not need to kill the microorganisms that cause the biofilms.

The novel compounds will be used as a coating on pipes, filters, membranes, air conditioning ducts and other surfaces in contact with water prone to formation of biofilms. The coating is environmentally friendly and effective against both fungal and bacterial biofilms.

Biofilm-related problems cost industry tens of billions of dollars annually by corroding pipes, reducing heat transfer or hydraulic pressure in industrial cooling systems, plugging water injection jets, and clogging water filter and pipes. The novel invention can be used for industrial water treatment, prevention of biofilm formation on filtration membranes, paints and coatings, irrigation pipelines and swimming pools. It can be used for household cleaning, and more. It will also lower costs of desalination and water recycling processes by reducing energy consumption due to corroded or clogged pipes.
