Process for biologically combating
The invention relates to a method for controlling the proliferation of Pseudomonas , with the exception of the treatment methods applied to the human or animal body, characterized in that it uses protozoa of the Willaertia magna species, and also to a disinfecting agent containing such protozoa.
1. A method for controlling the proliferation of Pseudomonas , with the exception of the treatment methods applied to the human or animal body, comprising contacting a gas or liquid stream or a solid surface with an amoebic protozoa of the species Willaertia magna corresponding to the strain deposited under number PTA-7824 at the ATCC or the strain deposited under the number PTA-7825 at the ATCC.
2. The method as claimed in claim 1 , characterized in that it is implemented for the disinfection of sanitation water or industrial water distribution networks, cooling circuits for industrial plants, air-conditioning networks, or industrial surfaces.
3. The method as claimed in claim 1 , characterized in that it is implemented for controlling the formation of biofilms in water pipes, or surfaces possibly in contact with human or animal food products.
4. A method for eliminating Pseudomonas in water or liquids circulating in the pipes or networks to be treated, comprising adding a protozoa corresponding to the strain deposited under number PTA 7824 at the ATCC or to the strain deposited under number PTA 7825 at the ATCC, to said water or liquids.
5. The method as claimed in claim 4 , characterized in that said protozoa is in the form of an aqueous solution or suspension.
