Abstract

L'invention concerne un procédé de réduction de la concentration en protéine prion infectieuse d'une matière sous forme liquide, sous forme de particules ou sous forme de fibres, contaminée ou suspectée d'être contaminée avec la protéine prion infectieuse comprenant : - une étape (a) consistant à mettre en contact et mélanger ladite matière contaminée avec au moins une bactérie qui sécrète une ou plusieurs enzymes hydrolytiques, y compris protéolytiques, vis-à-vis de ladite protéine prion infectieuse et, - une étape (b) d'incubation de la ou des bactéries avec ladite matière contaminée pendant une période de temps suffisante à l'obtention d'un pourcentage de réduction désiré de la concentration en protéine prion infectieuse dans ladite matière contaminée.
