Definitions
- the present invention relates to the arrangement and the implementation of a new apparatus for enzymatic catalysis comprising immobilized oxidoreductases in order to produce a continuous flow of radicals and oxygenated chemical substrates with compositions suitable for specific industrial applications.
- Oxidoreductases are a group of enzymes widely distributed in living organisms where they participate, in a regulated manner, in the various reactions of metabolism.
- peroxidases - and in particular lactoperoxidase (EC N ° 1.11,1.7) which appears abundant in the natural state in the milk of bovine - have been widely studied during the last decades because of their biological properties particularly interesting.
- Lactoperoxidase (LP) industrially extracted from cheese whey, has proven to be the essential element of a powerful natural antimicrobial system which plays a decisive role in the protection of young new born mammals against neonatal digestive microbial infections .
- This natural antimicrobial system has 3 components:
- lactoperoxidase present in milk at an average rate of 30 ⁇ gr per milliliter
- an oxidizable substrate the thiocyanate ion (SCN " ) food metabolite secreted naturally in milk at a concentration of 0.02 to 0.26 millimeter
- H 2 O 2 hydrogen peroxide
- lactoperoxidase catalyzes, at the expense of hydrogen peroxide, the production of oxygen radicals and oxidized substrates with biocidal activity according to the following reaction:
- the ubiquitous O 2 - superoxide anion is a powerful oxidizing agent which leads to the generation of new free radicals such as hydroxyl radicals. (OH-), hydroxyperoxyle (0 2 H) trioxide (.O 3 ) which are themselves converted into H 2 O 2 .
- the OSCN-oxythiocyanate product is in equilibrium with its acid form HOSCN. In the presence of sufficient quantities of hydrogen peroxide, the oxidation reaction of the thiocyanate ion continues towards even more oxidized oxyacid derivatives according to the following reactions:
- lactoperoxidase system has been shown to exhibit antimicrobial activities with respect to various microorganisms such as bacteria (Staphylococci, Listerias, Colibacilli, Salmonella, Pseudomonas, Mycoplasmas), protozoa (Cryptosporidia), viruses (Bacteriophages)
- biocidal formulations takes place in the form of bathing, spraying, spraying or dusting the products to be treated and protected.
- These methods of implementation require the use of quantities of enzymes proportional to the areas or volumes of the products treated and therefore prove to be expensive and incompatible with the economic constraints of the market.
- the variability of the various environmental parameters linked to the treated products greatly limit the practical implementation of the system as well as its local efficiency due to rapid degradation of the useful free peroxidase.
- US Patent No. 5,389,369 describes a bactericidal system based on the contact of a haloperoxidase with microorganisms in the presence of hydrogen peroxide, chlorine or bromine and amino acids.
- the different components are prepared and stored separately until they are mixed in solution at the time of use.
- Patent No. W96 / 38548 describes peroxidase compositions and methods for producing disinfecting and sterilizing solutions stored in anaerobic pressurized containers that can be activated by oxygen in the air at the time of use.
- Patent No. W97 / 15661 describes a microporous substance which selectively traps viruses and pathogenic microorganisms in the blood in order to subject them to close biocidal activity generated by an oxidative system linked to the microporous substance.
- the present invention relates to a new apparatus with immobilized enzymes making it possible to produce in a practical and high quantity, from different predetermined chemical compositions, a concentrated and continuous flow of oxygenated free radicals and oxidized substrates, in liquid or vapor phase, usable remotely for washing, decontamination, sanitization of various food products, including water, and industrial materials as well as for detoxification and sanitation polluted fluids in environmental engineering.

- the retained enzymatic mixture generates, from lactose, hydrogen peroxide (H 2 0 2 ) according to the following global reaction:
- Lactose ⁇ .Galactosidase Galactose + glucose Glucose Oxidase gluconolactone + H 2 0 2 »
- the preparation of the enzyme-carrying membrane can be carried out by simple adsorption of the enzyme solution as follows:
- the three preceding solutions are mixed, in equal parts, in a final solution in which the nylon membrane is immersed (at a rate of 30 ml of solution per membrane of 30 ⁇ 30 cm) which adsorbs approximately 80 ⁇ g of enzymatic proteins per square centimeter after contact with 15 min at room temperature.
- the membrane is then rinsed with 3 times 100 ml of phosphate buffer pH 7.5 and then saturated by immersion in 100 ml of a sterile 2% bovine casein solution in phosphate buffer, pH 7.5, for 15 min at room temperature . After a further rinsing with 3 times 100 ml of phosphate buffer, the membrane is drained and then dried at -20 ° C under vacuum and stored at 4 ° C, in a dehydrated atmosphere until its final insertion by mechanical fixing or by bonding to the internal walls of the tank ( Figure n ° 1).
- This embodiment of the invention makes it possible to obtain prolonged storage of the milk for an average of 7 days at 10 ° C. (cf. results in table 1 of the bacteriological experimentation carried out during the application of the apparatus).
- the apparatus thus constituted can be used repeatedly, on several successive batches of milk, for several weeks. It is easily regenerable by renewing the membranes.
- This set of characteristics makes it compatible with practical, repetitive and inexpensive use, which makes it an effective device for treating, sanitizing and stabilizing liquid foods such as milks and dairy products, fruit juices and drinks for a prolonged storage compatible with enhanced food safety.
