CA 2497339

At least one alkyl paraben is used in an aqueous antimicrobial preservation composition for eliminating or reducing the microbial content of a microbially contaminated separation matrix, which is to be used in a housing of a separation device, the separation matrix being microbially contaminated. Also, in a method of producing a separation matrix with eliminated or reduced microbial content, the method comprises the steps of providing said separation matrix, microbially contaminated, in a housing or container; adding an aqueous antimicrobial preservation composition, which comprises at least one alkyl paraben, to said separation matrix in said housing or container; allowing said aqueous antimicrobial preservation composition to exert its effect in said housing or container until the number of colony forming units (CFU) per g preservative composition is sufficiently reduced; and rinsing said aqueous antimicrobial preservation composition from said housing or container.

Selon l'invention, au moins un alkyl-parabène est utilisé dans une composition de conservation antimicrobienne aqueuse permettant d'éliminer ou de réduire la teneur microbienne d'une matrice de séparation contaminée par des microbes, destinée à être utilisée dans un logement d'un dispositif de séparation, la matrice de séparation étant contaminée par des microbes. Ainsi, dans une méthode de production d'une matrice de séparation à teneur microbienne éliminée ou réduite, on amène ladite matrice de séparation contaminée par des microbes dans un logement ou dans un contenant; on ajoute une composition de conservation antimicrobienne aqueuse qui comprend au moins un alkyl-parabène à ladite matrice de séparation dans ledit logement ou contenant ; on permet à ladite composition de conservation antimicrobienne aqueuse d'exercer son effet dans ledit logement ou contenant jusqu'à ce que le nombre d'unités formant une colonie (UFC) par g de composition de conservation soit suffisamment réduite ; et on rince ladite composition de conservation antimicrobienne aqueuse dudit logement ou contenant.
