Context and Objectives



Biofilms are responsible for billions of dollars in production losses and treatment costs in the industry every year. Indeed biofilms involve :

  • Food spoilage or poisoning in the food industry
  • Pathogens' persistence and dispersal in health industry
  • Corrosion and diameter reduction of pipelines

    Assuming that the environment is over-saturated with harmful chemicals such as biocides, whose long-term health effects still have to be elucidated, there is a great need for novel solutions to reduce detrimental biofilm effects.
    Thus, we develop a new generation of solution against biofilms in industry, which allows to reduce :

  • The use of harmful chemical reagents in cleaning processes
  • The cleaning costs for industrialists

    PROJECT STRATEGY


    Our solution is based on engineered bacterial "torpedos" capable of infiltrating, destroying biofilms (KILL) and protecting the cleaned surfaces by either a surfactant coating (COAT option), or by establishment of a positive biofilm ( STICK option).




    • Inacessible biofilms in pipes should be destroyed
    • Delivery of active substance within the biofilm should be facilitated by the tunneling activity of Bacillus swimmer cells


    • Bacillus strains are:
      • non pathogenic
      • do not cause equipment deteroriation by corrosion


      • This biocide-alternative strategy provides an money-saving and environementally friendly solution for the control of unwanted biofilm
