Definitions

  • Microorganisms also referred to as microbes, in the sense of the present invention are microscopically small organisms and include, in particular, bacteria, fungi, algae, protozoa and viruses. According to the invention, these microorganisms are at least partially inactivated photodynamically. The term inactivation also includes neutralization of the microorganisms. This includes, in particular, the destruction or dissolution (lysis) or prevention of the multiplication of the microorganism or the prevention of microorganism-related biofilm formation.

Abstract

L'invention concerne un procédé et des moyens pour l'inactivation photodynamique de micro-organismes dans un lubrifiant réfrigérant au moyen d'un photosensibilisateur présentant un maximum d'absorption décalé dans une plage supérieure à 700 nm par un tensioactif anionique. Le décalage du maximum d'absorption du photosensibilisateur dans la plage de grandes longueurs d'onde supérieures à 700 nm permet une pénétration plus profonde du rayonnement excitant le photosensibilisateur dans le lubrifiant réfrigérant et ainsi l'inactivation photodynamique de micro-organismes dans ces zones plus profondes du lubrifiant réfrigérant.
