Method for evaluating the effectiveness of biocidal compounds against microorganisms colonizing porous materials

摘要

The present invention relates to a method for evaluating the effectiveness of biocidal compounds with respect to microorganisms colonizing porous materials, from a sample through which fluids are circulated, with: a step (a) saturating the sample of porous material with a first aqueous fluid; a step (b) of injecting into the sample a second fluid comprising nutrient (s); - a step (c) of injecting into said sample a third fluid comprising microorganisms; - a step (d) of injecting a fourth fluid comprising liquid nutrient (s); - a step (e) of injecting a fifth fluid comprising at least one biocidal compound; - a step (f) of measuring and analyzing at least one parameter, physical, chemical or biological, which is representative of an activity of microorganisms and which relates to a fluid leaving the porous material and / or to the porous material itself.
