Title
(EN) A METHOD OF DECONTAMINATING A CEMENTITIOUS OR A METALLIC SURFACE
(FR) PROCEDE DE DECONTAMINATION D'UNE SURFACE EN CIMENT OU METALLIQUE
Abstract
(EN)
A method for the decontamination of a cementitious or a metallic surface having contaminants is described. The method comprises the steps of supplying to said surface at least one microorganism under conditions conducive to growth of said at least one microorganism; maintaining said conditions conducive to growth of said microorganism and the generation of an acid or other metabolite to degrade said surface to a desired depth; terminating said conditions conducive to growth upon achieving at least said desired depth of degradation; removing the products of said degradation; treating said degradation products; and, disposing of said treated degradation products wherein the at least one microorganism is a citric acid generating microorganism.
(FR)
Procédé de décontamination d'une surface en ciment ou métallique portant des contaminants, qui consiste à apporter sur ladite surface au moins un micro-organisme dans des conditions favorisant la croissance dudit micro-organisme, à maintenir lesdites conditions favorisant la croissance du micro-organisme et conduisant à la production d'un acide ou autre métabolite pour décomposer ladite surface jusqu'à une profondeur désirée; à stopper les conditions favorisant la croissance une fois la profondeur de décomposition désirée obtenue; à évacuer les produits de ladite décomposition; à traiter les produits de la décomposition et à jeter les produits de décomposition traités, ledit micro-organisme au moins étant un micro-organisme produisant de l'acide citrique.
