ABSTRACT:
A method for cleaning and disinfecting a surface at least partly covered by a biofilm layer comprising the steps of contacting the biofilm with a cleaning composition comprising one or more hydrolases, e.g. a hydrolytic enzyme produced by a strain of the fungus Aspergillus aculeatus, in an amount effective for either fully or partly removing or releasing the biofilm layer from the surface; and contacting the biofilm with a bactericidal disinfecting composition comprising an oxidoreductase such as an oxidase, a peroxidase or a laccase, in an amount effective for killing the living bacterial cells present in the biofilm. In particular, a disinfecting composition comprising laccase at concentration between about 0.01 to about 1000 mg protein/ml composition and an oxidation enhancer such as methyl syringate.
