Abstract
Description
본 발명은 김치, 막걸리 등에서 내산성, 내담즙성, 항염증 우수 프로바이오틱스 후보 유산균을 선발하여, 상기 유산균을 적용한 김치를 제조하는 방법에 관한 것이다.The present invention relates to a method for preparing kimchi using the lactic acid bacteria by selecting lactic acid bacteria excellent in acid resistance, bile resistance, and anti-inflammatory probiotics in kimchi, makgeolli, etc.
프로바이오틱스는 인체에 이로운 역할을 하는 살아있는 균으로 락토바실러스 카세이(Lactobacillus casei)를 비롯한 락토바실러스(Lactobacillus) 속 11종, 비피도박테리움(Bifidobacterium) 속 4종, 및 스트렙토코커스(Streptococcus) 1종, 락토코커스(Lactococcus) 1종, 엔테로코커스(Enterococcus) 2종 총 19종이 식약처에 등록되어있으며 우리나라에서는 상기 19종만을 고시형으로 프로바이오틱스라 인정하고 있다. 하지만, 유산균 및 발효 복합물을 개발하여 현재까지 10종정도가 개별형으로 인증 받았으며 다양한 연구진이 다양한 유산균을 연구하고 있는 실정이다.Probiotics are living bacteria that play a beneficial role in the human body, including Lactobacillus casei , 11 species of the genus Lactobacillus , 4 species of the genus Bifidobacterium , and 1 species of Streptococcus , lactobacillus. A total of 19 species, 1 species of Lactococcus and 2 species of Enterococcus, are registered with the Ministry of Food and Drug Safety, and only the above 19 species are recognized as probiotics in the notification form in Korea. However, after developing lactic acid bacteria and fermentation complexes, about 10 types have been certified as individual types, and various researchers are studying various lactic acid bacteria.
대부분의 프로바이오틱스는 동물에서 유래하여 그것을 사람을 포함한 동물인 숙주에게 공급하여 항암, 항염 등 다양한 기능성을 가지고 있지만, 동물에서 유래한 유산균과 비교하여 식물성에서 유래한 유산균은 많은 연구가 되어있지 않다.Most probiotics are derived from animals and supply them to animal hosts, including humans, to have various functions such as anticancer and anti-inflammatory, but compared to animal-derived lactic acid bacteria, plant-derived lactic acid bacteria have not been studied much.
김치는 배추를 기존 재료로 하여 다양한 채소들이 유산균에 의해 발효된 세계적인 식물성 발효식품으로, 풍부한 미네랄, 비타민, 식이섬유 등 다양한 기능성이 보고되고 있다. Kimchi is a world-class vegetable fermented food in which various vegetables are fermented by lactic acid bacteria using cabbage as an existing ingredient, and various functionalities such as rich minerals, vitamins, and dietary fiber have been reported.
소비 트렌드와 김장 문화의 변화로 집에서 담궈먹는 김치보다는 상품화 김치 시장이 많이 확대되고 있다. 이를 위해 김치 품질의 균일화, 규격화를 위해 다양한 연구를 진행하고 있으나, 발효유제품처럼 아직까지 종균화가 이루어지지 못하였다는 점이 가장 큰 문제점이다. 초기 균수와 균종이 일정하지 않기 때문에 발효유제품과 같은 발효시스템을 사용할 수 없다. 김치의 상업화를 위해서는 우수한 유산균을 활용하여 종균화가 되어야한다. Due to changes in consumption trends and kimchi-making culture, the commercialized kimchi market is expanding much more than kimchi made at home. To this end, various studies are being conducted to uniformize and standardize the quality of kimchi, but the biggest problem is that spawning has not yet been achieved like fermented milk products. Since the initial number of bacteria and species are not constant, fermentation systems such as fermented milk products cannot be used. In order to commercialize kimchi, it must be spawned using excellent lactic acid bacteria.
이에 김치에 적용 가능한 유산균을 종균화하여, 품질이 균일한 김치를 제조하는 방법이 요구되었다.Accordingly, a method of producing kimchi with uniform quality by spawning lactic acid bacteria applicable to kimchi has been required.

Since most of the probiotics currently notified by the Ministry of Food and Drug Safety are lactobacilli, only lactobacilli were selected from various strains under natural fermentation conditions primarily using a lactobacillus selection medium.
도 4는 김치, 막걸리, 효소액 등을 0.85 중량% NaCl로 희석하고 선택배지에 접종하고 배양하여 단일 콜로니를 얻고, 시퀀싱하는 과정을 개략적으로 도시한 것이다.Figure 4 schematically shows the process of diluting kimchi, makgeolli, enzyme solution, etc. with 0.85 wt% NaCl, inoculating and culturing a single colony in a selective medium, and sequencing.
도 4를 참조하면, 시료(김치, 막걸리, 효소액 등)를 스토마커로 분쇄하여 배수별로 희석(0.85 중량% NaCl)하였다. 이후 락토바실러스 선택 배지(LBS-media; Lactobacillus selection media)와 MRS 배지(media)에 아세트산(acetic acid)을 첨가하여 배지를 준비하였다. 첫 배양에는 락토바실러스 선택 배지를 사용하였으며, 계대배양에는 MRS 배지(media)를 사용하였다. 배양은 37℃에서 24시간 동안 배양하고 단일 콜로니를 얻을 때까지 계대배양하였다. 순수한 단일 콜로니를 얻은 후 그람염색 한 후 현미경 통해서 그람양성, 단간균 또는 간균인 콜로니들만 수집하고 아닌 경우 리스트에서 제거하였다. 상기 조건에 따라 수집된 균주는 16S rRNA 시퀀싱을 수행하였다.Referring to FIG. 4, samples (kimchi, makgeolli, enzyme solution, etc.) were pulverized with a stomacher and diluted (0.85 wt% NaCl) by multiple. Then, acetic acid was added to Lactobacillus selection media (LBS-media) and MRS media to prepare a medium. Lactobacillus selection medium was used for the first culture, and MRS medium was used for subculture. The culture was cultured at 37° C. for 24 hours and subcultured until a single colony was obtained. After obtaining pure single colonies, they were Gram-stained, and only Gram-positive, monobacterial, or bacillus colonies were collected through a microscope, and if not, they were removed from the list. The strains collected according to the above conditions were subjected to 16S rRNA sequencing.
<실험예 1-2. 락토바실러스 예상 균주 동정><Experimental Example 1-2. Lactobacillus predicted strain identification>
실험예 1-1에서 분리한 락토바실러스 예상 균주를 OD(optical density)값이 빠르고 현미경으로 본 세포의 모양 등을 통해 선발한 결과, 34가지 균주가 선발되었다. 선발된 분리균은 16S rRNA의 염기서열의 분석을 통해 동정하였다. 프라이머는 유니버설 PCR 프라이머(Universal PCR primer)인 27F (5-’AGAGTTTGATCMTGGCTCAG-3’) 1492R (5’-TACGGYTACCTTGTTACGACTT-3’)을 사용하였고, PCR은 초기 변성(initial denaturation) 5분, 94℃에서 45초간 변성 (denaturation), 55℃에서 60초간 풀림(annealing) 및 72℃에서 60초간 확장 사이클(extension cycle)을 35회 수행하였다. PCR산물의 염기서열은 ㈜솔젠트 (Daejeon, Korea)에 의뢰하여 분석하였다. 계통도(Phylogenetic tree) 작성은 BLAST 네트워크 서비스(network service)와 미국 국립생물정보센터(National Center for Biotechnology Information)에서 얻은 다른 균종의 16s rRNA 유전자 염기서열을 이용하여 RDP(Ribosomal Database Project)의 시퀀스 매치 프로그램(seqMatch program)에서 서열 일치도가 높은 표준 균주들의 16S rRNA 유전자 염기서열들을 얻었다. 그리고 DDBJ(DNA Data Bank of Japan)를 통해 계통분류학적 유연관계를 분석한 후, 트리뷰(treeview)를 이용하여 이웃-결합 방법(neighbour-joining method)과 거리 매트릭스 데이터(distance matrix data)를 사용하여 확인하였다. As a result of selecting the predicted Lactobacillus strains isolated in Experimental Example 1-1 through a fast OD (optical density) value and the shape of cells seen under a microscope, 34 strains were selected. The selected isolates were identified through 16S rRNA nucleotide sequence analysis. Universal PCR primers, 27F (5-'AGAGTTTGATCMTGGCTCAG-3') 1492R (5'-TACGGYTACCTTGTTACGACTT-3') were used as primers, and PCR was performed with initial denaturation for 5 minutes and 45°C at 94°C. Denaturation for seconds, annealing for 60 seconds at 55°C, and extension cycles for 60 seconds at 72°C were performed 35 times. The nucleotide sequence of the PCR product was analyzed by requesting Solgent Co., Ltd. (Daejeon, Korea). The phylogenetic tree was created using the BLAST network service and the 16s rRNA gene sequences of other strains obtained from the National Center for Biotechnology Information, using the RDP (Ribosomal Database Project) sequence matching program. (seqMatch program), 16S rRNA gene sequences of standard strains with high sequence consistency were obtained. And after analyzing phylogenetic relatedness through DDBJ (DNA Data Bank of Japan), using treeview, neighbor-joining method and distance matrix data were used. and confirmed.

표 1을 참조하면, 모든 균주가 락토바실러스(Lactobacillus) 속에 포함되어 있었으며 퍼멘텀(fermentum) 2종, 플란타럼(plantarum) 7종, 파라카세이(paracasei) 6종, 람노서스(rhamnosus) 4종, 브레비스(brevis) 5종, 사케이(sakei) 5종, 파라부쉬네리(parabuchneri) 3종, 컬바투스(curvatus) 2종 이었다.Referring to Table 1, all strains were included in the genus Lactobacillus ,
<실험예 1-3. 내산성 측정><Experimental Example 1-3. Acid resistance measurement>
발효식품에서 분리한 유산균이 프로바이오틱스로서의 기능을 가지기 위해서는 소화관을 통과해서 장까지 생존해야 한다. 선택배지와 그람양성 등 현미경 관찰에서 수집한 균주를 소화관 중 위와 같은 환경에서 장까지 살아갈 수 있는 능력을 알아보기 위해 위산과 유사한 pH의 조건에서 내산성 확인을 하였다. 이를 위해 MRS 배지(broth)에 접종하여 37℃에서 3시간 배양방법으로 테스트하였다. 생존률 확인은 균주를 MRS 배지(broth) 20ml에 37℃ 24hr 배양 후 스프레딩(spreading) 하여 균주 수를 측정하는데, 염산(HCl)을 이용하여 pH 3.0로 보정하여 만든 MRS 배지(broth)에 1 중량% 접종하여 37℃의 온도 조건에서 1시간, 2시간, 3시간 배양 후 각각 스프레딩(spreading) 하여 균주 수를 측정하였다. In order for lactic acid bacteria isolated from fermented foods to function as probiotics, they must pass through the digestive tract and survive to the intestine. In order to examine the ability of the strains collected from microscopic observation, such as selective medium and Gram-positive, to survive to the intestine in the above environment in the digestive tract, acid resistance was confirmed under conditions of pH similar to gastric acid. To this end, it was inoculated into MRS medium (broth) and tested by a 3-hour incubation method at 37 ° C. To confirm the survival rate, the strain is cultured in 20 ml of MRS medium (broth) at 37 ° C for 24 hr, and then the number of strains is measured by spreading. After % inoculation and incubation for 1 hour, 2 hours, and 3 hours at a temperature of 37 ° C., the number of strains was measured by spreading, respectively.
생존률(%) = pH 3.0 조건에서 1시간 배양한 균주/ 균주 수 * 100 Survival rate (%) = strain cultured for 1 hour at pH 3.0 / number of strains * 100
표 2는 표 1에서 선발한 34가지 균주의 내산성을 시간에 따라 측정하여 표로 나타낸 것이다.Table 2 is a table showing the acid resistance of the 34 strains selected in Table 1 measured over time.
<실험예 1-4. 내담즙성 측정><Experimental Example 1-4. Measurement of bile resistance>
표 3은 황소의 담즙이 포함된 배지에 균주를 배양하여 내담즙성 생존률(%)을 측정하여 표로 나타낸 것이다.Table 3 is a table showing the biliary survival rate (%) measured by culturing the strain in a medium containing ox bile.
표 3에서 내산성 실험 3시간 뒤에 70% 이상 생육을 보이는 균주 중 락토바실러스(Lactobacillus) 속의 종류와 내산성을 고려하여 19 균주를 선정하여 내담즙성 실험을 수행하였다. 구강을 통해 섭취된 유산균은 위액(내산성 실험)을 통과한 뒤 담즙이 존재하는 십이지장을 거쳐 최종 목적 부위는 장에 도달해야 그 기능적인 효과를 가지게 되므로 내담즙성 테스트는 매우 중요하다. 0.3 중량% 황소의 담즙(Difco사, oxgall)이 포함되어 있는 MRS 배지(broth)에 균주를 1 중량%(OD 값 일정) 접종하여 37℃의 온도조건에서 6시간 배양한 후 스프레딩(spreading) 하여 균수를 측정하였다.In Table 3, 19 strains were selected in consideration of the type and acid resistance of the Lactobacillus genus among the strains showing growth of 70% or more after 3 hours of the acid resistance test, and the bile resistance test was performed. Lactic acid bacteria ingested through the oral cavity pass through gastric juice (acid resistance test), pass through the duodenum where bile exists, and reach the final target site in the intestine to have its functional effect, so the bile resistance test is very important. 1% by weight (OD value constant) of the strain was inoculated into MRS broth containing 0.3% by weight of ox bile (Difco, oxgall), incubated for 6 hours at 37 ° C, and then spread The number of bacteria was measured.
생존률(%) = 0.3 중량% 황소의 담즙(oxgall) 조건에서 6시간 배양한 균주/ 균주 수 * 100Survival rate (%) = strain cultured for 6 hours under 0.3 wt% oxgall conditions/ number of strains * 100
표 3을 참조하면, 담즙 조건하에서 대부분의 균주가 생존율이 높은 경향성을 보였다. 프로바이오틱스 대조구로는 전세계에서 가장 많이 쓰이고 있는 락토바실러스 람노서스(Lactobacillus rhamnosus) LGG 균주를 사용하였다. 락토바실러스 람노서스(Lactobacillus rhamnosus) LGG 균주는 내담즙 생존률이 91%로 나타났고, 분리균주 중에서는 락토바실러스 플란타럼(L. plantarum) HJ-Ki의 내담즙 생존률이 96%로 가장 높은 값을 나타내었고, 대부분 80% 이상의 값을 나타내었다.Referring to Table 3, most of the strains showed a high survival rate under bile conditions. As a probiotics control group, Lactobacillus rhamnosus LGG strain, which is the most used in the world, was used. Lactobacillus rhamnosus ( Lactobacillus rhamnosus ) LGG strain showed a survival rate of 91% in bile, and among the isolates, Lactobacillus plantarum ( L. plantarum ) The survival rate of HJ-Ki in bile showed the highest value at 96%, and most of the values were above 80%.
<실험예 1-5. 김치모사배지에서 생육관찰><Experimental Example 1-5. Growth Observation on Kimchi Mosaic Medium>
내담즙성을 확인한 19가지의 분리균주 중 10개의 프로바이오틱스 균주만을 김치 종균으로 사용하기 위하여 다음 실험으로 김치와 같은 유사한 환경에서 배양하여 생장을 확인하였다. In order to use only 10 probiotic strains among 19 isolates with bile resistance confirmed as kimchi spawn, growth was confirmed by culturing in a similar environment such as kimchi in the following experiment.
본 실험에서 사용한 김치모사배지를 제조하기 위하여 배추 700g, 무 200g, 부추 50 g, 생강 10g, 마늘 20g, 굵은 소금 60g, 피쉬 펩톤(Fish peptone) 5g 멸균 증류수를 준비하였다. 각각의 채소는 세척하고 적당한 사이즈로 절단하여 준비한 주재료와 굵은 소금을 믹서기에 넣고 5분간 분쇄하였다. 분쇄된 분쇄물은 깔때기를 이용하여 1L 시약병에 채우고 냉장고에서 24시간 동안 절여서 영양성분을 식물조직에서 추출하였다. 상기 추출액에 피쉬 펩톤(Fish peptone) 5g을 첨가한 뒤 70℃의 진탕 항온 수조(shaking water bath)에서 30분간 저온 살균한 뒤 7000rpm, 10분 조건에서 원심분리하고 상층액을 분리하였다. 분리된 상층액은 멸균수로 2배 희석하여 적절한 크기의 멸균 용기에 옮겨 보관하면서 실험하였다.To prepare the kimchi simulated medium used in this experiment, 700 g of Chinese cabbage, 200 g of radish, 50 g of leek, 10 g of ginger, 20 g of garlic, 60 g of coarse salt, and 5 g of fish peptone were prepared in sterile distilled water. Each vegetable was washed and cut into appropriate sizes, and the prepared main ingredients and coarse salt were put in a blender and ground for 5 minutes. The pulverized material was filled in a 1L reagent bottle using a funnel and marinated in a refrigerator for 24 hours to extract nutrients from plant tissue. After adding 5 g of fish peptone to the extract, it was pasteurized in a shaking water bath at 70 ° C. for 30 minutes, centrifuged at 7000 rpm for 10 minutes, and the supernatant was separated. The separated supernatant was diluted 2-fold with sterile water and transferred to an appropriately sized sterilized container for storage.
MRS 배지에서 전배양한 대조구(류코노스톡 메센테로이데스(Leuconostoc mesenteroides) ATCC8293)와 앞서 분리한 10개 균주는 김치모사배지에 접종하여 8℃인큐베이터에서 5일간 배양하였고 24시간마다 흡광도를 측정하였다.The control ( Leuconostoc mesenteroides ATCC8293) pre-cultured in the MRS medium and the 10 strains previously isolated were inoculated into the Kimchi simulated medium and cultured in an 8 ° C incubator for 5 days, and the absorbance was measured every 24 hours.
도 5는 발효 기간에 따른 대조구와 10가지 균주의 흡광도(OD)값을 측정하여 나타낸 것이다.Figure 5 shows the measured absorbance (OD) values of the control and 10 strains according to the fermentation period.
도 5를 참조하면 흡광도 측정 결과 대조구는 김치와 유사한 환경에서 급속하게 생육하여 발효 4일차까지 흡광도가 증가하여 가장 높은 값을 나타내었다가 발효 5일차에는 급격하게 감소하였다. 분리균주는 중 락토바실러스 플란타룸(L. plantarum) HJ-Ki 균주가 김치모사배지에서 가장 우수한 생육을 보여 김치원재료 및 낮은 온도에서 종균으로 잘 사용이 가능할 것으로 판단되었다. 다음으로 락토바실러스 플란타룸(L. plantarum) Ho 및 락토바실러스 퍼멘텀(L. fermentum) HJ-C1 균주가 김치와 유사한 조건에서 잘 생육하였으며, 분리균주 중에는 락토바실러스 파라카세이(L. paracasei) MO-C1 균주의 생육은 발효 4일차 까지는 높은 활성을 유지하다가 발효 5일차에는 대조구 및 실험구 중 가장 낮은 값을 나타내었다. Referring to FIG. 5, as a result of measuring the absorbance, the control group grew rapidly in an environment similar to that of kimchi, and the absorbance increased until the 4th day of fermentation, showing the highest value, and then rapidly decreased on the 5th day of fermentation. Among the isolates, the Lactobacillus plantarum HJ-Ki strain showed the best growth in the kimchi simulated medium, and it was judged that it could be used as a raw material for kimchi and as a spawn at low temperature. Next, Lactobacillus plantarum ( L. plantarum ) Ho and Lactobacillus fermentum ( L. fermentum ) HJ-C1 strains grew well under conditions similar to kimchi, and among the isolates, Lactobacillus paracasei ( L. paracasei ) MO The growth of the -C1 strain maintained high activity until the 4th day of fermentation, but showed the lowest value among the control and experimental groups on the 5th day of fermentation.
따라서 내산성, 내담즙성 및 김치모사배지에서 가장 우수한 균주로는 락토바실러스 퍼멘텀(L. fermentum) HJ-C1, 락토바실러스 플란타룸(L. plantarum) HJ-Ki, 락토바실러스 플란타룸(L. plantarum) Ho, 락토바실러스 파라카세이(L. paracasei) MO-C1, 락토바실러스 람노서스(L. rhamnosus) B1-A 다섯균주를 최종 선정하였다.Therefore, the best strains in acid resistance, bile resistance and kimchi-simulated medium are Lactobacillus fermentum ( L. fermentum ) HJ-C1, Lactobacillus plantarum ( L. plantarum ) HJ-Ki, Lactobacillus plantarum ( L. Five strains were finally selected: plantarum ) Ho, Lactobacillus paracasei ( L. paracasei ) MO-C1, and Lactobacillus rhamnosus ( L. rhamnosus ) B1-A.

<실험예 1-7. 항염증 활성평가><Experimental Example 1-7. Anti-inflammatory activity evaluation>
균주의 항염증 활성 평가는 LPS로 자극된 RAW 264.7 세포에서 가열 사멸된 균주의 효과를 측정하는 방식으로 수행하였다. RAW 264.7 세포(5×105cfu )를 96 웰 플레이트(well plate)에 접종하고 20시간 동안 배양하였다. 이후, 상등액을 모두 제거하고 FBS(fatal bovine serum)가 함유되지 않은 세럼-프리(serum-free) DMEM 160 μL와 시료 100 μL를 첨가한 이후 염증 유발 물질로 1 μg/mL의 대장균(Escherichia coli)으로부터 분리된 LPS(lipopolysaccharide from Escherichia coli, Sigma-Aldrich) 20 μL를 처리하고 24시간 동안 재배양하였다. 배양 후, 각 웰(well)의 배양 상층액을 동량의 그리스(Griess) 시약과 혼합하고 실온에서 15분 동안 암실에서 반응시킨 뒤 540nm에서 측정하였다. 아질산염 농도는 아질산나트륨의 희석액을 표준으로 하여 계산하였다.Evaluation of the anti-inflammatory activity of the strain was performed by measuring the effect of the heat-killed strain on RAW 264.7 cells stimulated with LPS.

도 6을 참조하면, LPS 처리는 LPS를 처리하지 않은 대조군에 비해 NO 생성을 현저히 증가시켰다. 그러나 정조절(PC; positive control)로 NO 합성효소 억제제인 메틸 아르기닌(methyl arginine)을 처리한 경우, LPS군에 비해 NO생성을 용량 의존적으로 억제하였다. 또한 B1-A 균주를 제외한 실험된 모든 균주들은 LPS 그룹에 비해 NO생성에 대한 유의한 억제 활성을 나타내었다. 특히 H0 균주는 LGG 균주와 비슷한 활성을 나타내었고, HJ-C1 균주, HJ-Ki 균주, MO-Ci 균주는 WCFS1 균주 보다 더 유의한 억제 활성을 보였다.Referring to Figure 6, LPS treatment significantly increased NO production compared to the control group not treated with LPS. However, when treated with methyl arginine, an NO synthase inhibitor, as a positive control (PC), NO production was inhibited in a dose-dependent manner compared to the LPS group. In addition, all tested strains, except for the B1-A strain, exhibited significant inhibitory activity against NO production compared to the LPS group. In particular, the H0 strain showed similar activity to the LGG strain, and the HJ-C1 strain, HJ-Ki strain, and MO-Ci strain showed more significant inhibitory activity than the WCFS1 strain.
RAW 247.7 세포에서 염증을 유발하는 전구염증매개 효소인 COX-2(cyclooxygenase-2)의 발현양을 확인하기 위해 세포를 6개의 웰 플레이트(well plate)에 접종하고 24시간 배양하였다. 시료를 처리한 이후 LPS(1 μg/mL)를 처리하여 24시간 배양한 뒤, 배지를 제거하고 PBS로 세척한 후, 트리졸 RNA 분리 시약(Trizol RNA isolation reagent)(Invitrogen, Carlsbad, USA)으로 RNA를 추출하였다. 리젠 익스프레스 제1 스트랜드 cDNA 합성 키트(LeGene Express 1st Strand cDNA Synthesis System Kit)(LeGene Biosciences, San Diego, CA, USA)를 사용하여 적절한 양의 RNA를 cDNA로 역전사 시켰다. COX-2의 발현 정도는 합성된 cDNA, 10pmol의 특정 프라이머 및 SYBR 그린 믹스(SYBR Green Mix)를 포함하는 PCR 마스터 믹스(PCR Master Mix)를 CFX96 실시간 PCR(CFX96 real-time PCR)(Bio-Rad, CA, USA)를 이용하여 실시간 유전자 정량 분석하였다. In order to confirm the expression level of cyclooxygenase-2 (COX-2), a pro-inflammatory mediating enzyme that induces inflammation in RAW 247.7 cells, the cells were inoculated into 6 well plates and cultured for 24 hours. After processing the sample, it was treated with LPS (1 μg/mL) and incubated for 24 hours, then the medium was removed, washed with PBS, and treated with Trizol RNA isolation reagent (Invitrogen, Carlsbad, USA). RNA was extracted. An appropriate amount of RNA was reverse transcribed into cDNA using the LeGene Express 1st Strand cDNA Synthesis System Kit (LeGene Biosciences, San Diego, CA, USA). The expression level of COX-2 was measured by CFX96 real-time PCR (CFX96 real-time PCR) (Bio-Rad , CA, USA) was used for real-time gene quantification analysis.
도 7은 LPS(Lipopolysaccharide)의 처리에 따른, 대조구, LPS(Lipopolysaccharide) 처리구, 및 7가지 균주의 COX-2 발현 수준을 나타낸 것이다.Figure 7 shows the COX-2 expression level of the control group, LPS (Lipopolysaccharide) treatment group, and 7 strains according to LPS (Lipopolysaccharide) treatment.
상기 도 7은 GAPDH(Glyceraldehyde-3-phosphate dehydrogenase)를 참조 유전자로 하여 표준화(normalization)한 후 결과를 분석하여 그래프로 나타내었다. 표적 유전자의 상대적 발현 수준은 델타-델타 Ct(ΔΔCt) 방법으로 계산하였다. LPS 처리는 LPS 처리를 하지 않은 대조군에 비해 COX-2의 mRNA 발현 수준을 극적으로 증가시켰다. 실험된 모든 균주는 LPS 그룹에 비해 COX-2의 발현 수준을 유의하게 억제하였다. 이러한 결과는 균주의 처리가 상업적인 프로바이오틱스인 WCFS1 및 LGG와 유사하게 COX-2의 발현을 억제하는 활성을 가지고 있기 때문에 PGE2의 생성을 억제할 수 있음을 나타낸다.7 shows a graph after normalization using GAPDH (Glyceraldehyde-3-phosphate dehydrogenase) as a reference gene and then analyzing the results. The relative expression level of the target gene was calculated by the delta-delta Ct (ΔΔCt) method. LPS treatment dramatically increased the mRNA expression level of COX-2 compared to the control group without LPS treatment. All strains tested significantly suppressed the expression level of COX-2 compared to the LPS group. These results indicate that the treatment of the strain can suppress the production of PGE2 because it has an activity to inhibit the expression of COX-2 similar to commercial probiotics, WCFS1 and LGG.
