본 연구의 목적은 한국 전통 음식 김치에서 분리한 유산균의 특성을 연구하기 위해 형태학적, 생화학적 특성을 조사하였다. 한국의 전통 발효 식품에서 젖산균을 확인하기 위해 분리된 균주의 그람염색을 수행한 후 Macrogen에서 16S rRNA 분석 결과, DKGF9(Lactobacillus plantarum), DKGF1(Lactobacillus paracasei ), DKGF8(Lactobacillus casei ), DK207(Lactobacillus casei ), DK211(Lactobacillus casei )이 확인되었다. 우리는 한국의 전통 발효 식품인 김치에서 분리된 5가지 LAB의 기본 생물학적 활성에 대한 실험을 수행했다. 37℃, 55℃, 65℃, 75℃에서 각각 5분, 15분 5균주의 내열성 확인 결과, 상업 균주인 Lactobacillus acidophilus LA-5의 내열성과 유사하거나 더 높음을 보여주었다. 장내부착능에서는 선발균주 모두 상용균주와 비교했을 때 10⁷ CFU/mL 이상으로 우수한 결합능을 보여주었고, KCTC(한국생명공학연구원 생물자원센터)에서 분양받은 Escherichia coli KCTC1682, Salmonella enterica KCTC2054, Bacillus cereus KCTC3624 3종을 활용한 항균활성 결과, 모든 균주는 상업용 균주인 L. acidophilus LA-5와 비교하여 유사하거나 더 높은 항균 활성을 나타냈다. 단백질분해능력 실험에서, 5개의 균주는 clear-zone의 직경이 24시간에서 72시간으로 갈수록 점차 증가하고, L. paracasei DKGF1이 가장 큰 직경을 갖고 있어 단백질분해능력이 가장 우수한 것으로 나타났다. 5개의 균주로부터 선택된 3개의 균주는 ABTS, DPPH, FRAP, Hydroxyl radical scanenging 활성을 포함하여 다양한 항산화활성 효과를 나타냈다. 결과적으로, 5가지 균주 중에서 우수한 기능성을 갖는 L. paracasei DKGF1이 잠재적인 프로바이오틱스 활성을 나타내며, 건강 관련 제품의 개발에 유용한 균주라고 판단된다. The purpose of this study was to investigate the probiotic properties of lactic acid bacteria (LAB) isolated from a Korean traditional food kimchi. Gram staining was performed by Macrogen (Macrogen, Inc.) for identification of the LAB. Five strains of LAB were identified, including DKGF9 (Lactobacillus plantarum), DKGF1 (L. paracasei ), DKGF8 (L. casei ), DK207 (L. casei ), and DK211 (L. casei ). The biological activities of the isolated strains were assessed. The results showed that heat resistance of the strains was similar to or higher than the commercial strain L. acidophilus LA-5. Indirect testing of the ability of the strains to attach to the mucin layer revealed that DKGF9, DKGF1, and DKGF8 have high binding affinities for the mucous layer. All strains showed antimicrobial activity similar to or higher than the commercial strain LA-5. In proteolysis experiments, the diameters of proteolysis zones of the five strains increased in the period of 24-72 h, with DKGF1 exhibiting the largest zone diameter. Three strains were selected based on their antioxidant activities. Among the five isolated strains, L. paracasei DKGF1 showed potential probiotic activity, and thus, it may be useful for the development of health-promoting products.

濟州地域의 酪農産業은 草地와 氣候 等이 自然的 條件과 牛乳의 需要에 比하여 절대적으로 供給이 不足한 狀態에 있는 與件 및 地域産業의 均衡的 發展과 住民所得 增大 等을 考慮할때 必須的으로 育成 發展시켜야 할 必要性이 있으나 이에 對한 調査硏究는 매우 低調한 實情에 있는 點을 堪案하여 1987年 7月부터 1988年 7月까지 1年동안 濟州道의 酪農現況을 調査하고 115個 搾乳牛 飼育農家를 對象으로 地城別 規模別로 酪農農家의 實態를 調査分析하므로서 濟州地域 乳牛飼育과 酪農經營에 關한 基礎資料를 마련코져 本 硏究를 遂行하였는바, 그 第2報로서 道內 酪農農家 및 牧場의 一般分析과 飼育現況 및 施設設備 現況에 對한 調査分析結果를 要約하면 다음과 같다. 1. 一般槪況 經營主의 人的事項을 보면, 女性經營者가 擡頭되고 있고, 陸地部에서는 젊은 新規酪農가들의 增加가 顯著하나 濟州地域의 境遇 41∼51歲로 長年層이 많고, 學歷은 高卒이상이 75%로서 높은 水準이나 過去보다는 低下되고 있었다. 酪農前職業은 一般農業이 67.1%로 제일 높았으며, 가장 큰 規漠(D:31頭以上)에서 公務員 等 比農業前職이 많았다. 酪農經歷은 新規比率이 높아져가고 있는 陸地部와는 달리 6∼9年의 經歷이 가장 높았으며, 調査農家의 67.1%가 兼業酪農形態였고, 經營主가 牧場에 常住하는 農家는 87.7%였다. 平均家族數는 4.75人이고 牧夫는 農家當 In Cheju island, it is positively neccessary that we have to bring up and develope the dairy industry in order to increase the resident's income and develope the local industry. But the study and investigation for this subject are very rare and inactive. In this study, we surveyed and analyzed the actual feeding and managerial condition of the 73 dairy farm households kept milking cows for one year, from 1987, 7 to 1988, 8. We carried out these study in order to get the fundamental data and information about feeding and management of dairy cattle raised in Cheju area. The results are summarized as follows: The average ages of dairy farm owners were 41 to 50 years old. This is higher level than that of mainland's farmers. 75% of the dairy farmers graduated from high school or college. The former occupations of the dairy farm owners were agriculture(67.1%) and so on. Dairy Farming career of the farmers was 6-9 years and this is longer than that of mainland's farmers. 67.1% of investigated farmers have a subsidiary business and 87.7% of dairy farm owners worked for 24 hours at their dairy farm. These two kinds of levels are higher than those of mainland's dairy farm owners. The average feeding size per farmer was 9.48 heads. The management records of their dairy farms were rarely kept. The total numbers of dairy cattle raised in Cheju area were 2,163 heads in 1987, 11 and 2,753 heads in 1988, 5. The dairy cattle herds were composed of 11-27.6% calf, 40.9-50.2% multipara cow and 31.2-33.9% milking cow. The component ratio of multipara and milking cow was very low. The number of dairy cows per feeding farm as 19-24 heads(8.7-9.8 head in multipara). This is more than that of the mainland. But this ratio is also low and is not proper. The yearly increasing ratio of dairy cattle was 19.3% and was much higher level than that of mainland. 81.5% of cows had an easy labor but 13.8% of cows were dystocia. The cause of death and culling was mainly reproductive disorder and desease. The average area for dairy farm was 30,290 pyong per farm and 1,844 pyong per mature cattle. The ratio of rent area was high level(24.7%). The farm land was composed of 32.4% forage crop field, 36.1% improved grassland, 23.5% wild grassland and 1.6% stock yard and building site. The farm building, facilities and equipments were more unreasonable and lower than those of mainland except silo. The actual condition of large and small instruments(tractor, milker, cooler etc.) was better than those of mainland and was much improved, compared with the condition of 10 years ago.

이은,이학철 한국낙농학회 1983 韓國酪農學會誌 Vol.5 No.3

Salinomycin(s) 飼料添加가 反芻動物 Rumen內 微生物相에 미치는 影響과 그에 따르는 活性變化를 究明하기 위하여 平均體重이 19∼20㎏되는 在來牡山羊 8頭를 對照區(4頭)와 SL 30ppm區(4頭)로 나누어 42日間 經日的(0, 7, 14, 28, 42, 日), 經時的(0, 4, 8時)으로 Rumen內 原蟲 및 細菌의 構成과 分布, amylase 및 urease의 活性, 揮發性脂肪酸(VFA) 總量과 그 組成 그리고 Rumen의 pH에 미치는 影響에 對해서 調査했다. 1. 原蟲總蟲數에 있어서 SL區는 試驗開始後 14日째까지 減少하는 傾向을 보이다가, 그 以後 增加하는 傾向을 보였으나 試驗終了日인 42日째까지도 完全한 回復을 보여주지 않았으며 試驗全期間의 平均總蟲數는 對照區보다 낮은 傾向이었다(P<.05). 2. 試驗全期間을 通하여 兩試驗區에서 檢出된 原蟲種數는 Isotrichidae目에 屬하는 것이 3種, Ophryoscolacidae目에 屬하는 것이 11種이었으며 SL區가 對照區에 比하여 原蟲種構成에 있어서 單純化되는 傾向이었으며 屬別로 본 原史構成에서는 全毛蟲類(Holotricha)가 多少 增加하는 傾向을 나타내었다. 3. 細菌總數 있어서, SL區에서 多少 增加하는 傾向을 보였으나 試驗全期間의 平均細菌 總數는 兩區間에 有意한 差가 認定되지 않았으며 細菌類構成의 經日的變動에 있어서도 相互 類似한 傾向을 보여주었다. 4. 型態 및 Gram染色性으로 類別된 各 細菌類의 構成比 增減에 對한 變異程度는 細菌種類에 따라 다르고, SL區는 對照區에 比하여 Gram陰性菌이 增加하고 Gram濫性菌이 減少하는 傾向이었다. 5. 細菌의 酵素活性에 있어서 Amylase活性은 試驗全期間, SL處理區가 對照區에 比해서 多少 높은 活性値를 보이면서 顯著한 變動을 나타내었으며, urease活性値는 經日的 變動에 있어서 一定한 傾向을 볼 수 없었다. 그러나 上記 2個 酵素平均活性値는 ○區間 有意한 差를 나타내지 않았다(P>.05). 6. 試驗全期間을 通하여 Rumen內 pH變化는 ○區間에 類似한 傾向을 보여주었으며, 平均 pH 値間에도 有意한 差를 나타내지 않았다(P>.05). 7. 生成 VFA總量은 ○區間 有意한 差를 보여주지 않았다. 그러나 VFA 各組說酸別로는 試驗開始 7日째부터 SL區는 對照區에 比해 acetate가 減少하고 propionate가 增加하는 傾向이었으며, butyrate에 있어서는 SL區가 對照區에 比해 多少 낮은 數値로 變動되었으나 平均値에 있어서 兩區間 有意한 差가 認定되지 않았으며 나머지 徵量의 2種 VFA(Ci 5, Ci)도 ○區間 類似한 傾向으로 變動하고 平均値에 있어서 有意한 差가 認定되지 않았다. The present experiments were conducted to determine the effect of feeding salinomycin on rumen bacterial flora and protozcal fauna, on bacterial activity involving amylase and urease, on ruminal pH and volatile fatty acids. Eight Korean native goats averaging 19.3㎏ of body weight were randomly alloted to the diets supplmented with salinomycin at the level of 0 and 30 ppm. After 3 week adaptation period the animals were fed the experimental diet. Ruminal fluids were collected and examined just before feeding, and 4, 8 hrs after feeding on days 0, 7, 14, 28 and 42. 1. The total number of ruminal protozoa was markedly decreased with salinomycin diet from the 7th to 14th day, although it was gradually increased after that, it was not recovered at the end of experiment. A significant difference (P<0.05) among treatments could be noted in the total number of ruminal protozoa throughout the experimental period. 2. A total of 14 protozoal species were detected throughout the experimental period: 3 species in Isotrichidae, 11 species in Ophryoscolaciade. The number of protozoal species of salinomycin group was lower than that of control group and the number of Holotricha was increased in salinomycin group. 3. The total of ruminal bacteria tended to increase in salinomycin group but no significant difference (P<0.05) was observed among treatments and the changes in distribution of bacterial type were similiar among treatments. 4. The bacterial fluctuation pattern was varied with bacterial types and the total number of Gram-negative bacteria increased with salinomycin diet, while that of Gram positive bacteria decreased. 5. Amylase activity had tendency to increase in salinomycin group but no significant ditterence (P<0.05) was observed among treatments. 6. In the urease activity, no significant difference (P>0.05) was found among treatments throughout the experimental period. 7. In the ruminal pH values, no significant difference (P>0.05) was found among treatments throughout the experimental period. 8. The total ruminal VFA concentration was found not to be affected by the salinomycin treatment. The molar portion of acetate in ruminal fluid was reduced (P>.05) by salinomycin diet, but that of propionate increased (P>.05) from the 7th to the end of the experimental period. The molar portion of butyrate tended to decrease but no significant difference (P>.05) was noted among treatments, neither was in isovalerate nor in valerate.

이명재,김현욱,최충국,권일경 한국낙농학회 1983 韓國酪農學會誌 Vol.5 No.1

國內에서 生産되는 9개회사의 市乳를 81年 1月부터 12月까지 每年 2回씩, 總 227점에 對하여 物理化學的 性質을 硏究하였으며 그 結果를 要約하면 다음과 같다. 1) 市乳의 乳脂肪, 乳蛋白, 乳糖, 總固形分 및 無脂乳固形分의 含量은 各各 3.48, 3.08, 4.71, 11.96 및 8.48%였으며 pH, 適定酸度 및 氷点은 各各 pH 6.63, 0.16% 및 -0.522。H였다. 2) 各 組成分 含量은 季節에 따라 變化하며 대체로 봄과 겨울이 여름과 가을에서 보다 더 높았고, pH는 여름과 가을에 낮았으며 適定酸度는 그 反對이고, 氷点은 가을에 특히 낮았다. 3) 各 助成分 含量間에는 高度의 正의 相關이 있었고, 氷点은 乳糖 및 無脂固形分 含量과 負의 相關이 있었다. 4) 各 助成分 및 性質에 있어서 製品들 間에 乳蛋白을 제외하고는 有意差(P<0.01)가 있었다. 乳脂肪含量은 K製品이 3.58%로서 가장 높았고, F製品이 3.21%로서 가장 낮았으며, 乳糖, 總固形分 및 無脂乳固形分 含量은 G製品이 각각 4.83, 12.19 및 8.64%로서 가장 높았으며, D製品이 各各 4.58, 11.73 및 8.29%로서 가장 낮았다. 適定酸度는 G와 J제품이 0.18%로서 가장 높았고 C제품이 0.15%로 가장 낮았으며, 氷点은 D제품이 -0.508。H로서 현저히 높았고 A제품이 -0.531。H로서 가장 낮았다. 5) 이상의 結果로 미루어 現市乳의 가장 큰 問題點은 氷点이 높은 것이라고 할 수 있으며 加水 및 젖산생선으로 因한 市乳의 品質低下를 막기 위해서는 農家와 乳加工場 및 유통과정에서의 계속적인 제품의 위생관리가 필요하다고 할 수 있다. This study was carried out to find the physicochemical properties of market milk produced in Korea. Market milk from 9 dairy companies were analyzed for their gross composition and some other properties, twice a month from Jan. to Dec, in 1981. Milko Scan 104 was used to determine fat, protein, lactose, solidsnot-fat and total solids in samples collected from retail stores in Suwon area. The results obtained were summarized as follows; 1. The average contents of protein, fat, lactose, total solids and solids-not-fat were 3.08, 3.48, 4.71, 11.96 and 8.48%, and average values of pH, titratable acidity, freezing point of market milks were pH 6.63, 0.16% and 0.5222°H, respectively. 2. Average composition of market milks has shown large a variation with the seasons and was generally higher in spring and winter. pH was lower hut tituratable acidity was higher in summer and fall. Freezing point was lower in fall, especially. 3. There were highly positive correlations among the components, and freezing point had negative correlations with lactose and solids-not-fat content. 4. There were significant differences (p<0.01) in compositions and properties of various market milk, except protein. K product gave the highest fat content, 3.58% but F product gave the lowest, 3.21%, and G product gave the highest value of lactose, total solids and solids-not-fat contents(4.83, 12.19 and 11.73%) but D product gave the lower 4.58, 11.73 and 8.19%, respectively. G and J products gave the highest value of 0.18% but G product gave the lowest value of 0.15% of titratable acidity, and D product gave the highest freezing point,-0.508°H but A product gave the lowest, -0.53l°H. 5. In conclusion, it could be said that the most serious problem of Korean market milks was their high freezing point. To solve this problem, it is needed that the test program for the watered raw and market milk be forced in addition to other quality tests.
