TECHNICAL FIELD [0001] The present invention relates to a method for producing a pine needle prophylactic and pine needle probiotic composition,

TECHNICAL FIELD The present invention relates to a method for producing a pine needle prophylactic agent, a pine needle prophylactic composition prepared thereby, and a method for breeding cattle containing the same.

Antibiotics have been used extensively in livestock specifications for the purpose of treating and promoting growth of livestock since the 1950s. The use of antibiotics in livestock feeds at low quasi-therapeutical levels resulted in improved productivity such as disease control, growth promotion, and feed efficiency improvements in livestock and contributed to the increase in the incomes of both farms. However, as the amount of antibiotics used increases throughout the world, resistant bacteria against antibiotics are generated, causing problems of environmental pollution. In particular, recently, antibiotics-resistant bacteria that may be harmful to the human body due to the use of antibiotics have been reported, and Korea has also banned the use of antibiotics for livestock feed since July 2011.

Therefore, the development and research of materials that can replace antibiotics are underway, among which living microbial supply sources are in the spotlight for probiotics that can improve intestinal microflora and livestock productivity, and demand for farm households is also surging.

 Domestic probiotics market accounts for about 50 billion dollars, and the number and types of probiotics are increasing every year. For example, Korean Patent Registration No. 1197682 discloses a fermented probiotic as a feed additive. As a result, the number of probiotics producers has increased, and many probiotics have been manufactured and distributed. At the same time, many probiotics that have not been scientifically validated are on the market.

On the other hand, in Hadong County, Gyeongnam Province, the probiotics were manufactured using the microorganisms native to the pine needles, which are natural resources. However, since the conventional method for collecting the seeds was not selecting only the excellent strains but collecting all the bacteria present in the natural world, there was a concern about contamination by various kinds of bacteria or pathogenic microorganisms. The collected seeds were cultured using brown sugar, but not only the live cells were not grown, but the number of viable cells was less than the legal allowable value (10 6 or more per g) There were disadvantages. Therefore, systematic and scientific technology development is urgently required for enhancing the brand value of the local excellent brand Korean pearl beef, and for promoting the Korean pearl producer, Chinese pearl farming, and Korean-related industries.

According to the present invention, it is possible to search a useful microorganism from pine needle indigenous microorganisms, to select an excellent strain through enzymatic vitality and antimicrobial activity test, to produce a high quality pine needle prodrug through liquid culture and solid fermentation, And a method of raising cattle comprising feeding a feed containing the pine needle probiotic agent.

However, the problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

As a technical means for accomplishing the above technical object, the first aspect of the present invention provides a method for producing pine needle extract, Isolating lactic acid bacteria, Bacillus subtilis, and yeast strains having an antimicrobial activity against a fusarium species fungus having a cellulose hydrolysis activity from the pine leaf extract; Culturing the lactic acid bacteria, Bacillus subtilis and Yeast cells for 2 days to 6 days respectively; Adding a rice bran, molasses, water, bacillus subtilis and yeast bacteria to a solid fermentor and performing primary fermentation for 10 hours to 30 hours while stirring; And, after the first fermentation, further adding the lactic acid bacterium and performing secondary fermentation for 1 day to 6 days while stirring.

According to one embodiment of the present invention, the liquid culture of the lactic acid bacteria, Bacillus subtilis and Yeast cells may include culturing the lactic acid bacteria with Lactobacillus MRS broth, the Bacillus with LB broth, and the yeast with potato dextrose broth.

The second aspect of the present invention provides a pine needle procurement composition prepared by the method of the first aspect of the present application and having a number of microorganisms of 10 7 to 10 8 cfu / g.

A third aspect of the present invention provides a method of raising cattle comprising feeding the pine needle probiotics produced by the method of the first aspect of the present invention in an amount of 0.5 to 5% by weight based on the feed and feeding.

According to the manufacturing method of the pine needle prophylactic agent of the present invention, superior beneficial microorganisms can be selected and utilized in the pine pine pine leaf which is being fermented by the fermentation mycelium, that is, the pine pine native microorganism existing in the pine needle leaf microbial pine. From the indigenous microorganism derived from pine needles, It is possible to secure a strain having excellent vitality.

In addition, there is an advantage that seed culture can be smoothly grown and sufficient viable cell counts can be obtained by improving the seed culture method and the solid fermentation method which have been conventionally used.

In the solid fermentation step, rice bran and molasses which are easy to purchase raw materials, cheap and easy fermentation of microorganism can be used as a basic medium. For example, the base medium may be a weight ratio of raw water to water of 10: 1 to 10: 5, and the raw water may be used in an amount of about 50% to about 85% by weight based on the total weight of the medium. For example, molasses may be added thereto at a ratio of 0.1 to 5% by weight based on the raw steel.

The seed medium thus prepared can be inoculated in a liquid medium and then fermented. The liquid cultured seed bacterium may be added to the medium at the same ratio, for example, 0.1 to 10% by weight based on the basic medium, but may not be limited thereto.

According to one embodiment of the present invention, the liquid culture of the lactic acid bacteria, Bacillus subtilis and Yeast cells may include culturing the lactic acid bacteria with Lactobacillus MRS broth, Bacillus with LB broth, and yeast with potato dextrose broth, But may not be limited.

The second aspect of the present invention provides a pine needle procurement composition prepared by the method of the first aspect of the present application and having a number of microorganisms of 10 7 to 10 8 cfu / g.

A third aspect of the present invention provides a method of raising cattle comprising feeding the pine needle probiotics produced by the method of the first aspect of the present invention in an amount of 0.5 to 5% by weight based on the feed and feeding.

Research summary

In Experiment 1, Bacillus subtilis was selected as 'Ganoderma 4-2 ② (6-1)', lactic acid bacillus was identified as 'Yu 1-2 (8-1)' and yeast was identified as 'Hyo 4-1 ①'.

2. Establishment of liquid culture condition of selected useful microorganisms

Experiments to establish optimal liquid fermentation conditions using the selected useful microorganisms were carried out as follows.

Selection of seedlings: In Experiment 1, lactic acid bacteria, Bacillus subtilis, and Yeast strains, which were found to have excellent enzymatic activity and antimicrobial activity, were selected and used as seeds.

Conventional seed culture method: After the seeds were prepared, they were sprayed in a place where the pine needles were abundant in the wild mountain of Hyodang-myeon, Hadong-gun and left for about 5 days. This allowed them to inoculate the microorganisms present in the composted pine leaves. After the incubation for 5 days, the collected rice was collected and mixed with brown sugar and water at a ratio of 1: 1, sealed for about 1 week, and the cultured liquid was used as a seed.

New seed culture method: As described in Experiment 1 above, the pine needles that were composted were collected in the same place as the existing seed collection sites, and the first and second cultures were obtained to obtain excellent strains. Lactobacillus MRS broth, lactobacillus LB broth and yeast were cultured in a 39 ° C incubator for 4 days using Potato Derextrose broth at intervals of 1 day, And the number of bacteria was examined.

Survey item

Investigation of Optimum Liquid Fermentation Conditions: The medium components of the selected strains were mixed in a 2 L container in a laboratory, sterilized at 121 ° C for 15 minutes through a high pressure sterilizer, and inoculated with the selected bacteria in the sterilized medium, And the number of bacteria was measured.

Microbial counts: Lactobacillus was cultured on MRS agar, LB agar and PDA agar, and lactic acid bacteria, Bacillus subtilis, Yeast fungus and Fungi were analyzed. The cultured lactic acid bacteria were cultured in a CO 2 incubator at 39 ° C for 1 to 8 days. Bacillus, yeast and fungi were cultured in an aerobic incubator at 39 ° C for 1 to 8 days.

Results

The changes in the number of bacteria according to the culture period are shown in Table 3 below. Lactic acid bacteria, Bacillus subtilis and Yeast cells showed the highest number of bacteria about 4 days after the cultivation. Therefore, it was confirmed that fermentation of the seed culture was most effective for about 4 days. As a result, the bacterium was grown in the liquid culture by the conventional bacterium culture method, but the bacterium grew smoothly when the new culture method was applied, and the optimum culture period was confirmed to be about 4 days.

3. Establishment of technology for manufacturing pine needle probiotics using liquid cultures of selected useful microorganisms

In order to establish the technology for the production of pine needle probiotics, solid fermentation was carried out using a selected strain after liquid culture.

 The solid fermentation method was compared with the conventional method and the new method, and the blending ratio of the raw materials is shown in Table 4 below.

Figure 112016021460611-pat00004

In the conventional culture method, all raw materials are put into a solid fermenter and cultured at 39 ° C for 6 days. During the incubation period, the stirrer was stopped for 2 hours and then stirred for 30 minutes.

In the new culture method 1, rice bran, molasses, water, Bacillus subtilis, yeast and lactobacillus were all added to a solid fermenter and cultured at 39 ° C for 6 days. During the incubation period, the agitator was set under the same conditions as the conventional culture method.

In the new culture method 2, rice bran, molasses, water, Bacillus subtilis, and yeast were mixed in a solid fermenter and primary fermentation was performed at 39 ° C for 1 day. At this time, stirring of the stirrer was repeated for 30 minutes after stopping for 1 hour. On the second day, the lactic acid bacteria were mixed and then the second fermentation was carried out. In this case, the stirrer was stirred for 30 minutes after stopping for 2 hours and fermented for a total of 6 days. That is, the first fermentation was performed using aerobic microorganisms such as Bacillus subtilis and yeast bacteria, and the agitation of the anaerobic microorganism was mixed during the second fermentation after the first fermentation and the operation time of the stirrer was reduced Reduced supply of oxygen.

Samples were collected at 1, 2, 4, and 6 days during solid fermentation, and used for analysis. Microbial counts were performed in the same manner as described in Experiment 2.

Results

The results of investigating the changes in viable cell counts according to the fermentation conditions and the incubation period are shown in Table 5 below.

Figure 112016021460611-pat00005

In the change of the number of bacteria according to the fermentation period, the existing culture method showed the highest number of bacteria on the 4th day of fermentation and the new culture methods 1 and 2 showed the highest number of bacteria on the 2nd day of fermentation. Changes in the number of bacteria according to the fermentation conditions showed that lactic acid bacteria, Bacillus subtilis and Yeast cells were more than 10 4 to 10 5 on the 4th day of fermentation, whereas the new culture method 1 was more than 10 7 on the 2nd day of fermentation. However, the new culture method 2 was more than 10 8 on the 2nd day of fermentation and was higher than other culture methods.

In conclusion, it was confirmed that the optimum culture method for the solid fermentation, that is, the preparation of the pine needle prodrug, after the liquid culture of the selected strain was the new culture method 2 and the fermentation period was 2 days. In other words, it was confirmed that culturing for 1 day using Bacillus subtilis and yeast, aerobic bacteria for solid fermentation, and cultivation for 1 additional day using lactic acid bacteria were the best.

That is, according to the present invention, it is possible to obtain a strain having excellent enzyme activity and antimicrobial activity from indigenous fungus derived from pine needle, securing a liquid culture technique using a secured excellent strain, and producing a high quality pine needle probiotic preparation using liquid culture Technology can be established. In addition, from the economic and industrial point of view, it is possible to enhance the brand value of livestock products in Hadong County through the production of high quality pine needle probiotics, and it can be expected to increase the income of farm households by improving productivity of livestock through high quality pine needle probiotics.
