Description

Anti-fungal and anti-bacterial compositions against fish pathogenic bacteria}

The present invention relates to an antifungal and antimicrobial composition against fish bacterial pathogens, and more particularly, to an antifungal and antimicrobial composition of fish comprising at least one extract selected from the group consisting of red ginseng, rhubarb and bokbunja as an active ingredient. .

Aquatic fungi are mycelia that develop and develop spores only on dead cells or tissues, but have been reported to be very difficult to cure due to infinite reproduction by penetrating deep into healthy cells or three lobes after infection. There is also a high probability of developing aquatic fungal infections when there is trauma, when long-term or deteriorated feeds are fed, when nutrition is poor after wintering, and when the temperature changes in early spring are severe. In particular, because fertilized eggs have no movement and the fertilized eggs and the fertilized eggs are in contact with each other, when infected by aquatic fungi caused by the eggs, their spread is very fast and also occurs during spawning and incubation periods. Inflicts damage. Malachite Green, which has been used for aquatic fungal infections in freshwater fish, has been used worldwide since 1949. It has been banned, and its use has been banned entirely since 2003 in Korea and Japan. As malachite green has been identified as a carcinogenic substance and its use is banned, formalin, bronopol, humic acid, chlorine dioxide, and hydrogen peroxide are mainly used as alternative chemicals. The most commonly used formalin (formalin) is an aqueous solution of formaldehyde. Formaldehyde is a flammable colorless gas with an irritating odor. Soluble in water, 37% aqueous solution of formaldehyde is called formalin. Formalin is mainly used as antiseptic and preservative. Formaldehyde is very toxic to the human body, and when a person is exposed to more than 30 ppm of formaldehyde, symptoms begin to develop. Powerful protein coagulation invades skin and mucous membranes, and inhalation with gas can cause pharyngitis or bronchitis. High doses can lead to heart failure and death. If you take 100 mg (0.1 g) per kg of body weight, 50% of people die. This means that if 100 g of a person weighing 70 kg is ingested 7 g each, 50 of them will die. According to a Schenke report written in 1981, exposure to 30 ppm in air for 1 minute can cause symptoms such as memory loss and mental distress. When formaldehyde is disposed of, it is required to be incinerated at high temperature or melted and solidified at high temperature according to the Waste Chemicals Control Act and the Waste Management Act. As such, in the case of the use of chemicals such as formalin, as with malachite green, the possibility of adverse effects on the human body is very high. Therefore, in order to secure the safety of aquatic products, antifungal substances of natural materials are required.

Therefore, the present inventors have made diligent research efforts to overcome the problems of the prior art, when treating ginseng extract, rhubarb extract, bokbunja extract or mixtures thereof, as well as antifungal activity against aquatic fungi, as well as disease in aquaculture fish It was confirmed that the present invention can exhibit effective antimicrobial activity against the resulting Vibrio strain, Streptococcus strain and Edwardsiela strain, and completed the present invention.

Accordingly, the main object of the present invention is to provide a natural antifungal and antimicrobial composition having an antifungal and antimicrobial effect of inhibiting fish aquatic fungal infection with high safety and efficacy compared to formalin which has been used for aquatic fungal infection.

After grinding each of red ginseng, rhubarb and bokbunja, each of the above pulverized product was added to 70% methanol, 70% ethanol or water in 10% content, and extracted by soaking at 80 ° C. for 5 hours. . The red ginseng, rhubarb, and bokbunja were extracted from each of the three solvents (70% methanol, 70% ethanol and water), respectively, and thus the total extract samples were nine.

Example  2. Isolation and Identification of Aquatic Fungi

Aquatic fungi were isolated from the larvae of aquaculture farms, and three to five pure separation processes were performed. After aquatic fungi were selected, they were identified through sequencing of the internal transcript spacer (ITS), and finally Saprolegnia. parasitica was used.

Example  3. Antifungal Experiment

For antifungal experiments, formalin (formalin), a chemical used in aquaculture farms, and three medicinal plant extracts according to the present invention (Ginseng, Rhubarb, and Bokbunja extracts) were used as test materials. Specific antifungal experiments are as follows, the experimental schematic is shown in FIG.

A 0.8 mm stainless hole was placed on a GY (Yeast extract, 2.5 g; 10 g / L glucose) plate, and a hole was formed by pouring GY soft medium. Then, 50 μl of 10% medicinal plant extracts were applied to the formed holes, and 1 cm 2 aquatic fungus ( Saprolegnia) in the center of the medium. parasitica ) blocks were raised and incubated at 20 ° C. for 3 days. After incubation was completed, the size of the lowland was measured. The measurement results are shown in FIG. 2.

As shown in Figure 2a, as a result of treatment of aquatic fungi with formalin, the size of the lowland was 2 cm at 100 ppm diluted with formalin (37%), 100 cm at 0.2 ppm, and at 100 ppm for control (instead of formalin). It was found that the growth of aquatic fungi could not be prevented. On the other hand, as shown in Figure 2b and Table 1, when treating the medicinal plant extract according to the present invention was confirmed to significantly inhibit the growth of aquatic fungi, in particular, ginseng, rhubarb, bokbunja extract extracted with 70% methanol In the case of treatment of the low zones of 2.6, 2.95, and 2.9 cm, respectively, it was confirmed that the growth of aquatic fungus more effectively than when formalin was treated with 10,000 ppm.

Example  4. Antifungal Synergy Effect of Medicinal Plant Extracts

Through the antifungal experiment of Example 3, it was confirmed that the antifungal effect by mixing high ginseng, rhubarb, bokbunja extract (all 70% methanol solvent extract) showed high efficacy. The mixed extract samples were classified into four types, and were prepared by mixing the same weight ratios of red ginseng + rhubarb extract, red ginseng + bokbunja extract, rhubarb + bokbunja extract and red ginseng + rhubarb + bokbunja extract. Aquatic fungi used in antifungal experiments are the most common onset of aquaculture in Saprolegnia. parasitica was used. The antifungal test method was performed in the same manner as described in Example 3, and 50 μl of 10% mixed extract was applied to each sample. After completion of the final culture, the size of the lowland was measured. The measurement results are shown in Table 2 below.

As a result, it can be seen that the treatment of the mixed extract inhibits the growth of aquatic fungi more efficiently than the treatment of a single medicinal plant extract, and in particular, all three medicinal plant extracts mixed with red ginseng, rhubarb and bokbunja are treated. The lowest antifungal effect was found at 3.4 cm.

Figure pat00003

The antimicrobial test method is as follows. ST medium (NaCl 1.5%, Tryptic Soy Broth 30 g and agar 1.5% / 1 L), which is the medium of each strain, was poured into a plate (petri-dish) and hardened, and then a stainless hole having a diameter of 0.8 cm was hardened. It was placed on a plate. Then, in the ST medium composition, 10 mL of ST agar medium (ST soft-agar medium) containing agar content of 0.75% in the ST medium composition was adjusted to the absorbance (OD 600 ) of each strain to 0.1 100 After addition of μl, the medium containing the strain is poured and solidified onto the medium on which stainless holes are erected. Thereafter, after removing the stainless hole, 50 μL of the medicinal plant extract (Ginseng, rhubarb or bokbunja extract) according to the present invention was added to the resulting hole, followed by culturing for 18 hours in a 27 ° C. incubator, whether the experimental strains were grown around the hole. It was confirmed. If the effect is greater, a clear zone will appear around the hole, and in the case of a sample without antimicrobial activity, the strains grow around the hole so that the low zone is not visible. The diameter size of these lowlands indicates the antimicrobial activity of the extract. The measurement results are shown in Tables 4 to 6 below.
