Title
(EN) BIOFILM DISRUPTION LEADING TO MICROBIAL DESTRUCTION
(FR) PERTURBATION DE BIOFILM CONDUISANT À UNE DESTRUCTION MICROBIENNE
Abstract
(EN)
A method of treating biofilm having a protective extracellular polymeric substance (EPS) membrane attached to a surface applies chlorine dioxide to the biofilm attached a surface to disrupt the EPS membrane of the biofilm and thereby expose microbes in the biofilm to microbicide attack and death without detaching the biofilm from the surface.
(FR)
La présente invention concerne une méthode de traitement d'un biofilm ayant une membrane protectrice à base d'une substance polymère extracellulaire (EPS) fixée à une surface, laquelle méthode applique du dioxyde de chlore sur le biofilm fixé à une surface pour perturber la membrane à base d'EPS du biofilm et exposer ainsi des microbes dans le biofilm à une attaque microbicide et à la mort sans détacher le biofilm de la surface.
