Context and Objectives



Every year industries spend billions of dollars to get rid of the biofilms which develop in their installations. Indeed biofims are reponsible for :

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

    At the moment, industries have some solutions at their disposal to limit the biofilm development but they have generaly an environmental impact and/or an important cost.

    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).



    This tunneling activity of Bacillus subtilis swimmer cells enables to :
  • Facilitate the delivery of the active substances within the biofilm.
  • Destroy the inacessible biofilms in pipes.

  • Moreover Bacillus strains are non pathogenic and do not cause equipment deteroriation by corrosion.

    To sum up, this biocide-alternative strategy provides a money-saving and an environementally friendly solution for the control of unwanted biofilm.
