In this study, β-1,3/1,6-glucan, lactic acid bacteria, and β-1,3/1,6-glucan+lactic acid bacteria were tested for 10 weeks using an immunodeficient animal model infected with LP-BM5 murine AIDS virus On the immune activity. Cytokines production, plasma immunoglobulin concentration, T cell and B cell proliferation were measured. As a result, the T cell proliferative capacity which was weakened by immunization with LP-BM5 murine AIDS virus increased significantly T cell proliferative capacity compared with the red ginseng control group. B cell proliferative capacity was significantly higher than the infected control group. Increased B cell proliferation was reduced. In the cytokine production, IL-2, IL-12 and IL-15 in the Th1-type cytokine increased the secretion of IL-2, IL-12 and IL-15 compared to the infected control. The proliferative capacity of the treated group was higher than that of the mixed treatment group. TNF-α was significantly decreased compared with the infected control group. The IL-4, IL-6 and IL-10 levels were significantly inhibited in the infected control group and the Th1/Th2 type cytokine expression was regulated by immunohistochemistry. IgE, IgA, and IgG levels were significantly lower in the immunoglobulin secretion assay than in the control. As a result, the immunomodulatory effect of β-1,3/1,6-glucan+lactic acid bacteria was confirmed by mixing with LP-BM5 murine AIDS virus-infected immunodeficient animal model.

This study investigated quality characteristics of sourdough bread added with different amounts of lactic acid bacteria culture solution (LCBC) and cinnamon extract (Control: water 700 mL, sample A: water 670 mL+LCBC 30 mL, sample B: water 670 mL+LCBC 22.5 mL+Cinnamon extract 7.5 mL, sample C: water 670 mL+LCBC 15 mL+Cinnamon extract 15 mL, sample D: water 670 mL+LCBC 7.5 mL+Cinnamon extract 22.5 mL and sample E: water 670 mL+Cinnamon extract 30 mL). The weight of dough was not significant between samples, and the weight of bread was highest in samples D. The volume and specific volume were the highest in sample C but the baking loss rate was highest in the control (p<0.05). The L value, springiness and cohesiveness were decreased as addition of cinnamon extract increased. However, a value, b value, hardness, gumminess and chewiness were reversed. The sourdough bread produced by adding lactic acid bacteria culture solution improved the volume and texture. It was thought that it is helpful to add lactic acid bacteria culture solution and cinnamon extract for manufacturing a loaf of bread.

The objective of this study was to select yogurt starter from Korean traditional fermented foods. The 2 strains (KM24, KM32) among 50 strains of isolated lactic acid bacteria selected as starter based on milk clotting ability, antimicrobial activity against various pathogens, tolerance in artificial gastric and bile juice and growth in 10 % skimmed milk. The strains were identified as Lacobacillus plantarum (KM32) and Pediococcus pentosacesus (KM24) by 16S rRNA gene sequencing. Viable cell number of yogurt fermented with mixed strains (KM24 and KM32) was 9.66 log CFU/mL after fermentation for 48 h and maintained 109 CFU/mL during fermentation for 72 h at 37℃. The pH and titratable acidity of mixed cultured yogurt were 4.25% and 0.83% after fermentation for 48 h at 37℃, respectively. The physico-chemical characteristics of mixed cultured yogurt after fermentation for 48 h were 38.45 μg/mL (polyphenol content), 48.57% (DPPH radical scavenging activity) and 465.40 cp (viscosity), respectively. The mixed cultured yogurt maintained 109 CFU/mL of lactic acid bacteria during storage 10 days at 4℃. The viable cell number of yogurt prepared with mixed culture(KM32+KM24) maintained higher and than that of control (L. casei) during storage. These results indicated the potential use of selected strains (KM32+KM24) isolated from kimchi as a yogurt starter with strong acid tolerance and probiotics properties.

Background : 1-Deoxynojirimycin (DNJ) is a representative compound of the antidiabetic constituent in mulberry leaves (Morus alba L.). The hot water extracts of mulberry leaves were fermented with lactic acid bacteria in order to analysis the changes of the DNJ contents and α-glucosidase inhibition. Methods and Results : The mulberry leaves were extracted with hot water (121℃, 3 hr). The extracts were fermented with nine strains of lactic acid bacteria such as Lactobacillus acidophilus, in order to increase the contents of DNJ and α-glucosidase inhibition. DNJ contents in the fermented extracts were determinated by HPLC analysis. The α-glucosidase inhibition was mesured by comparing dose-inhibition curves of α-glucosidase and IC50 value. The DNJ contents after fermentation have increased in the almost fermented extracts. Especially, DNJ of the extracts fermented with L. acidophilus was increased from 8.38 ㎍ ㎖ -1 to 21.77 ㎍ ㎖-1. IC50 values of the α-glucosidase inhibition were shown to be decreased in the fermented extracts. The extracts fermented with L. casei KCTC 3109 was determined at 290.04 ㎍ ㎖-1, resulting it is lower about 140 ㎍ ㎖-1 than 429.76 ㎍ ㎖-1 of the control. Conclusion : From the above results, we may suggest that the lactic acid fermentation of mulberry leaves extracts can more enhance the hypoglycemic activities such as DNJ contents.

GABA 함량이 증가된 섬애약쑥 발효물의 제조를 위하여 섬애약쑥 추출물을 15% 첨가하여 제조한 식혜에 MSG를 0, 0.25, 0.5 및 1.0% 첨가하고, Lactobacillus brevis(KI271266)를 접종하여 3일간 발효하면서 일자별로 시료를 취해 이화학적 특성을 분석하였다. 발효기간이 경과할수록 탁도는 점차 감소하였고, 명도와 황색도는 증가하였고, 적색도는 감소하는 경향이었다. 가용성고형분도 점차 낮아져 발효 3일에는 19.70-20.80 °Brix의 범위였다. 환원당의 함량은 MSG의 첨가량이 많을수록 더 높았는데, 발효기간이 경과할수록 감소하는 경향이었다. pH는 4.65-4.83이던 것이 발효 3일 후에는 3.15-3.68로 낮아졌다. MSG의 첨가농도가 높을수록 GABA의 함량도 높았으며, 발효기간이 경과할수록 그 함량도 증가하여 MSG 1.0% 첨가군에서는 354.38 mg/L로 가장 높은 함량이었다. Fructose, glucose 및 sucrose는 발효 전에 비해 3일간 발효 후에 50-67%가 감소하였다. 유기산 중 propionic acid, oxalic acid, citric acid 및 fumaric acid의 함량은 발효기간의 경과와 더불어 감소하였고, lactic acid, acetic acid, succinic acid의 함량은 점차 증가하였는데, lactic acid의 증가폭이 가장 컸다. 3일간 발효가 완료된 발효물 중의 총 페놀화합물의 함량 및 DPPH 라디칼 소거활성은 동일한 경향으로 MSG 0.5% 첨가군이 유의적으로 가장 높았고, 다음으로 1.0% 첨가군이었다. 이상의 결과로부터 섬애약쑥 유산균 발효물 제조시 MSG를 첨가함으로써 발효물의 이화학적 특성에는 영향을 미치지 않으면서 GABA의 함량 증가가 가능함을 확인할 수 있었다.

GABA는 glutamic acid decarboxylase에 의해서 L-glutamic acid가 탈탄산화되어 생합성된 비단백질 아미노산이다. GABA는 식물에서 스트레스에 대항한 대응반응으로 생성된다. 사 람의 중추신경계에서는 주요 억제성 신경전달물질 중 하나로 항고혈압, 항당뇨 효능이 있 다고 알려져 있다. 본 연구에서 우리는 보리 잎과 옥수수 수염을 유산균과 함께 발효함으 로써 GABA 생성을 증진시키고자 하였다. 보리 잎과 옥수수 수염을 다양한 무게 비율로 조 합하여 혼합하였고, 30℃에서 48시간 동안 배양기 안에서 L. plantarium과 함께 발효시켰다. 발효된 혼합물을 열수 추출한 후, thin layer chromatography와 GABase assay를 이용하여 GABA의 생산을 분석하였다. 우리는 9:1 혼합발효추출물이 다른 비율의 추출물 보다 GABA 함량이 높은 것을 확인하였는데 이것은 혼합과 발효기술이 보리 잎과 옥수수 수염 내 GABA 양 증진에 효과가 있음을 의미한다. 또한 몇 가지 생리활성을 분석한 결과 혼합 발효추출물의 항산화 효능이 비발효 추출물에 비하여 증진되었고 세포독성은 나타나지 않 음을 확인하였다. 이러한 결과는 보리 잎과 옥수수 수염의 조합과 이것을 유산균과 함께 발효시키는 방법이 고함량의 GABA와 증진된 생리 활성을 지닌 기능성 식품으로서의 개발 가능성이 있음을 의미한다.

Demand for the development of non-antibiotic growth promoters (AGP) in animal production surged in recent years. However, elucidating the specific mechanisms and action of prebiotics, probiotics, and synbiotics as non-AGP in animals is still in progress. This work investigated and compared faecal microbiotas of weaned piglets under the administration of a basal diet (CON) and with prebiotic lactulose (LAC), probiotic Enterococcus faecium NCIMB 11181 (PRO), or their synbiotic combination (SYN). Although prebiotics and/or probiotics in the diet significantly increased alpha-diversity compared with CON values, no differences were detected in richness and diversity values among the treatment groups (LAC, PRO, and SYN). At phylum level, the Firmicutes to Bacteroidetes ratio increased in the treatment groups in comparison to the CON group, and the lowest abundance of Proteobacteria was found in LAC group. At family level, Enterobacteriaceae decreased in all treatments, especially more than 10-fold reduction in LAC group compared with CON group. At genus level, the highest abundance of Oscillibacter was detected in PRO group, the highest Clostridium in LAC group, and the highest Lactobacillus in SYN group; the abundance of Escherichia was lowest in LAC group. Clustering in the DAPC plots illustrated distinct separation of the feeding groups (CON, LAC, PRO, and SYN) from one another, showing that microbial communities had different compositions according to different feed additives. Effects of LAC and PRO treatments on the faecal microbiota suggest independent mechanisms; nonetheless, the impact of SYN might also be distinct from that when each are administered singly as LAC or PRO.

본 연구는 꽃송이버섯 원물과 꽃송이버섯 8% 첨가하여 유산균으로 발효한 꽃송이버섯 혼합물의 이화학적 특성 및 항산화 활성을 비교 조사하였다. 유산균 발효 꽃송이버 섯 혼합물의 수분, 조지방 및 조회분 함량은 버섯 원물에 비해 유의적으로 높게 나타났다(p<0.05). 꽃송이버섯원물 과 유산균 발효 꽃송이버섯 혼합물의 총 식이섬유소 중 불용성 식이섬유소가 각각 89.21%와 95.74%를 차지하였 다. 꽃송이버섯 원물의 β-glucan 함량은 38.03%으로 유산균 발효 꽃송이버섯 혼합물의 β-glucan 함량 5.44%에 비해 유의적으로 높게 나타났다. 꽃송이버섯 원물에는 유리당 중 glucose와 fructose만 함유하고 있으며, 유산균 발효 꽃송 이버섯 혼합물은 sucrose만을 함유하였다. 총 polyphenol 함량은 꽃송이버섯 원물과 유산균 발효 꽃송이버섯 혼합물 에서 유의적인 차이는 나타나지 않았다. 총 flavonoid 함량 은 유산균 발효 꽃송이버섯 혼합물이 꽃송이버섯 원물에 비하여 유의적으로 높게 나타났다(p<0.05).

The microbial composition in Nuruk, a Korean cereal fermentation starter, is a critical factor for the quality and organoleptic properties of traditional alcoholic beverages. This study was aimed at monitoring the compositional change and enzyme activity of culturable lactic acid bacteria (LAB) in two types of Nuruk fermented at different temperatures. All culturable LAB were isolated at various time points (0, 3, 6, 10, 20, and 30 days) and identified by 16S rRNA sequencing. In traditional Nuruk type A (TN-A), which was fermented at 36℃, the population of total culturable LAB during the fermentation period was between 104 and 105 log CFU/mL. On the other hand, the LAB population in traditional Nuruk type B (TN-B) fermented at 45℃ (primary fermentation for 10 days) and 35℃ (secondary fermentation for 20 days) was 102 log CFU/mL; however, these bacteria could not be detected after 6 days. Major LAB strains were identified in both Nuruk types: (1) from the MRS-culture of TN-A, Pediococcus pentosaceus at 3-30 days; (2) from MRS-culture of TN-B, P. pentosaceus at 3 days and Enterococcus hirae at 6 days. The protease activities of the dominant LAB isolated from the TN-A and TN-B cultures were within the ranges of 0.64~1.03 mg/mL and 0.74~0.81 mg/mL (tyrosine content), respectively, whereas the α-amylase activities were 0.75~0.98 mg/mL and 0.78~0.79 mg/mL (amylose content), respectively.

The physicochemical properties and storage stability of blueberries fermented by lactic acid bacteria were investigated. The viable cell count of lactic acid bacteria slowly increased to 5.96 log CFU/mL after 72 hr of fermentation. The pH decreased whereas titratable acidity increased after fermentation. The contents of total anthocyanin (31.52 mg/100 g) and cyanidin-3-glucoside (C3G) (5.41 mg/100 g) after 72 hr of fermentation were higher than those of non-fermented blueberries (16.10 mg/100 g and 2.21 mg/100 g, respectively). The L and a value decreased, and the b and △E value increased. The total polyphenol and flavonoid contents of fermented blueberries (2.21 g/100 g and 0.91 g/100 g, respectively) were higher than those of non-fermented blueberries (1.13 g/100 g and 0.49 g/100g, respectively). The DPPH radical scavenging activity and superoxide radical scavenging activity of the fermented blueberries were 30.74%, and 52.76%, respectively. The ferric reducing antioxidant power of the fermented blueberries (256.42 μM/g) was higher than that of non-fermented blueberries (191.52 μM/g). Anthocyanin and C3G content was stable in fermented blueberries after 42 days of storage. The results suggest that blueberries fermented by lactic acid bacteria have the potential to be functional materials in the food industry.

We isolated 105 strains of lactic acid bacteria (LAB) from home-made kimchi and breast milk-fed Korean infant feces on the basis of morphological analysis. This study aimed to compare the probiotic characteristics of selected strains of LAB including bile and acid tolerances, cholesterol assimilation and adhesion activity. Among the isolates of LAB, 54 isolates were identified as Lactobacillus plantarum (14 strains), L. brevis (12 strains), L. sakei (9 strains), L. acidophilus (3 strains), L. casei (1 strain), and L. fermentum (1 strain). Acid tolerances under artificial gastric juice, pH 2.5 for 2 h at 37°C, were significantly different among the Lactobacillus species. Lactobacillus acidophilus and L. plantarum strains exhibited high tolerance in acid and bile. Lactobacillus acidophilus strains exhibited high cholesterol assimilation activity and showed a significantly higher tolerance to 0.3% bile acid than other Lactobacillus strains (p<0.05). Based on these results, we selected the best strain, named NS1 (L. acidophilus) as a potential probiotics that can be utilized in the manufacturing of dairy foods and dietary supplements.

Intestinal lactic acid bacteria (LAB) for humans are closely associated to the host’s health because the presenceof LAB is an important bio-defense factor in preventing colonization and subsequent proliferation of pathogenic bacteria inthe intestine. Some probiotics such as Lactobacillus species can intoxication of carcinogens including chemical mutagens.The purpose of this study was to compare the ability of antimutagenesity among 24 strains of LAB isolated from infantfeces, yogurt and kimchi etc. The antimutagenic effects of protein fractions extracted from the cells of 24 LAB strains wereinvestigated using mutagens as 4-nitroquinoline-N'-oxide in Ames test (Salmonella Typhimurium TA 100). In the Amestest, dose-dependent activity was exhibited significantly against 4NQO. Three strains of Lactobacillus showed the highestanti-4NQO activitiy (62.1%) among the tested strains of LAB.

HACCP (Hazard Analysis Critical Control Point) has been receiving a worldwide recognition as a scientific andsystemic sanitary management technology in the food safety. At present, mandatory HACCP for dairy products is appliedin dairy processing plants and milk collection stage, while it is not applied in dairy farm and transportation. Therefore, it isrequired to establish HACCP application in all dairy industrial areas. The purpose of this study is to suggest an effectiveapproach to implement HACCP chain system in domestic dairy products. Most lactic acid bacteria has been useful toimprove gastrointestinal disorders such as diarrhea, constipation and reduce colon cancer risk and hydrocholesterol inKorea. The Ministry of Food and Drug Safety has increasingly applied the HACCP-chain system to secure the safety oflivestock products. Therefore, we suggest for the introduction of HACCP chain system in the dairy industry as follows.First, the system needs political support to activate. Second, the enterprise needs to recognize that it is essential system inan era of a consumer. Third, it should be utilized as an effective tool to enhance a brand value in the market. If there areobstacles in the implementation process for dairy products, governments, academia and relevant institutions should resolvea dispute together, which might enhance the level of livestock processing industry and hygiene safety management.

Obesity, most often defined as a body mass index (BMI) of ≥30 kg/m2 caused by an imbalance between energyintake and expenditure. It is widely recognized as the largest and fastest growing public health problem in the developed anddeveloping world. Obesity results by an increase in adipose tissue mass, resulting from the multiplication of fat cells fol-lowed by adipogenesis and increased deposition of intracellular cytoplasmic triglycerides. In this study, we investigated theanti-adipogenic properties of the extracts (KEs) obtained from Kimchi (Korean traditional fermented vegetable) fermentedusing Kimchi refrigerator under different storage conditions. The intracellular lipid droplets in the differentiated adipocyteswere also measured. We observed that the KEs significantly lower the contents of cellular triglyceride and formation ofintracellular lipid droplets. These results suggested that KEs have anti-adipogenic effects and may contribute to food indus-tries in developing functional.
