  • The aims of this study were to isolate spore-forming Bacillus strains that exhibit high digestibility and anti-pathogenic bacteria toward feed for calves. Total 136 spore-forming strains were isolated from finished feeds and their ingredients. Among them, 93 strains were identified as Bacillus species when analyzed by 16S rRNA sequencing. For industrial use, three strains named as Bacillus licheniformis SHS14, B. subtilis LCB7, B. amyloliquefaciens LCB10 were selected after evaluating the industrial standards that are related with heat and acid resistance, enzyme activities, and anti-pathogenic activities against Samonella dublin ATCC15480 and E. coli K99. After each culture, 3 selected strains were mixed together at 1:1:1 (v/v/v) ratio and then prepared as the mixed starter culture for feeding. The changes in microbial community were analyzed via 16S rRNA metagenomics. The initial community ratio among three strains was maintained even after manufacturing into final products. Also, in vitro, enzymatic and anti-pathogenic activities were almost same as those when cultured in single culture, and results of anti-pathogenic activities conducted with calves showed 90% activities against lincomycin, which would be indicative of a promising feed starter.

  • This study was conducted to examine the chemical composition of kiwifruit skin, and to est its anti-microbial activities and cytotoxicities, thus, exploring ways for the economic utilization of kiwifruit skin. Four varieties of kiwifruit were examined: Daeheung, Bidan, Haegeum No.1 and Hayward. Vitamin C content in the fruit skins of Bidan, Daeheung, Haegeum No.1 and Hayward were 72.44, 67.22, 62.51 and 61.44mg/100g, respectively. Total amino acids content in the fruit skins of Bidan, Haegeum No.1, Hayward and Daeheung ere 808.31, 706.02, 629.07 and 464.83mg/100g dry weight, respectively. K and Ca content ere $17.20-45.70{\mu}g/mL$ and $4.58-10.15{\mu}g/mL$. While, other inorganic matter contents were below $4.89{\mu}g/mL$. Anti-microbial activity of kiwifruit skin extracts, in terms of the diameter of inhibition zone when tested against five gram positive and three gram negative microbial trains (even in the concentration of 2,000mg/L), was less than 14.1mm. The hyperplasia inhibition of lung cancer cells by methanol extracts from Bidan and Haegeum No.1 using concentrations of 800mg/L were 27.7% and 14.5%, however, those from Daeheung and Hayward were below 3% Consequently, it will be useful to know that kiwifruit skin can be added to processed goods which demand for higher concentrations of vitamin C, amino acids, K and Ca.

  • This study was conducted to investigate the total lignin content and anti-oxidant activity in extracts of defatted sesame seeds (DSS) fermented with 15 strains of Bacillus subtilis. The anti-oxidant activities of DSS were analyzed both before and after fermentation. The total lignan content of the DSS extracts fermented with BCH3678 (1,613.8 mg/l) and BCH3572 (1,599.5 mg/l) were relatively high compared to other strains. Anti-oxidant activity was determined according to phenolic compound and flavonoid content and DPPH radical scavenging rate; the highest total phenolic compound content was provided by the DSS with SRCM103716 at 2,803.3 mg GAE/g which returned total flavonoid content of 1,553.1 mg/g as strong correlation of its anti-oxidant activity. The DSS extract fermented by SRCM103716 at 37℃ for 24 hr showed the highest DPPH scavenging rate at 66.5%. The fermented DSS extracts, regardless of strain, demonstrated higher anti-oxidative activity than the unfermented control, and these results suggest that such extracts could be useful as a potential source of bioactive compounds.

  • Flavonoid are large group of the polyphenolic compounds which are distinguished by an aromatic or phenolic ring structure and the phenolic compounds are induced by microbial infection, ultraviolet radiation, temperature and chemical stress. They are known for their antioxidant activity, anti-allergic, anti-inflammatory, anti-microbial and anti-cancer activities. In this study, changes in flavonoid content were investigated using heterologous chalcone isomerase (CHI) expression system. Also, phenolic compounds level was measured to examine the relation between flavonoids and phenols contents. Explants of lettuce (Lactuca sativa L.) were transformed with Agrobacterium tumefaciens LBA 4404 strain containing pFLH-CHI (derived from pPZP2Ha3) vector constructed with CHI gene from Brassica rapa. The putative transgenic plants were confirmed by genomic DNA PCR analysis. Also the transcription levels of the gene were analyzed by semi-quantitative RT-PCR with gene specific primers. The total flavonoid contents were increased at $T_0$ and $T_1$ generations over 1.4 and 4.0 fold, respectively. Total phenol contents also increased at $T_1$ generation. These results indicate that CHI gene plays an important role to regulate the accumulation of flavonoids and its component changes.

  • Ginseng is described as the "King of all herbs, "Man-root" or "Root of heaven" and regarded as the most powerful herbal remedy, particularly grown in Korea, China, Japan, Vietnam, and North America. It has been in existence for a long time. The most demanded herbal cure, Ginseng, principally the root, has long been employed in traditional Asian medicine. The extent of availability of bioactive combinations and their impact on the body differs between American and Asian ginseng. Asian ginseng, also known as Panax ginseng, has a more calming influence and is more advantageous than American ginseng, such as Panax quinquefolius. The pharmaceutical aspect of development and extraction with diverse morphological properties is examined. Saponins, glycosides, carbohydrates, polyacetylenes, amino acids, vitamins, volatile oil, enzymes are all present in the Phyto-content of Ginseng. Ginsenosides are saponins that are constituents of the triterpenoid dammarane and have anticancer, anti-cardiovascular, anti-microbial, anti-obesity, anti-inflammatory, and antioxidant properties. Ginseng, in particular, has the possibility to help with microbial invasion, inflammatory processes, oxidative stress, and diabetes. It developed nanoparticles and nanocomposite film technologies as novel drug delivery platforms for cancer, inflammation, and neurological illnesses. Furthermore, it offers a range of applications that will be vital for future growth.

  • Recently, there has been a great deal of interest in the applications of plant-based extracts to both cosmetic and medicinal industries. The objective of this study was to investigate the anti-inflammatory and antimicrobial effect of P. rigida extracts by water and ethyl acetate. Anti-inflammatory and anti-microbial effect of P. rigida extracts by water and EtOAc were investigated by using nitrite scavenging ability, nitric oxide production and anti-microbial ability. In the test of nitrite scavenging ability, P. rigida extracts by water and EtOAc showed 88.7% and 99% at 100 ppm concentration, respectively. The cell viability was measured using the MTT assay at 24 hours after P. rigida extracts as shown in over 80%. Anti-inflammatory effect was examined in LPS stimulated RAW 264.7 cells. NO productions in LPS and P. rigida extracts stimulated group were decreased in a concentration and were dependent on time as compared with LPS stimulated. The water extracts showed the highest inhibition at the 100 ppm concentration. In anti-microbial activity test, the water extract with 3.0 mg/disc resulted in the clear zone of 14 mm, and ethyl acetate with that of 15 mm for Staphylococcus aureus. However, P. rigida extracts didn't show any growth inhibitory effect on Esherichia coli. These results indicate that the extracts of P. rigida have anti-inflammatory activities as a cosmeceuticals.

  • Volatile odor substance originating from drying and making dry peel of tangerine from the fruit skin were collected through modern equipment. The anti-microbial activity of the substance against various skin-residing bacteria including acne, dandruff, athelete's foot, and gingivitis inducing microorganisms were tested. Anti-microbial activity was observed in purified oil, where 87 to 92% was D-limonene. Against P. acnes, 103$cfu/m{\ell}$ of P. acnes were suppressed at 0.1% Unshiu oil, and the MIC was measured to be 0.3%. Against P. ovale, a dandruff inducing bacteria, 104$cfu/m{\ell}$were suppressed at 0.1% Unshiu oil, and the MIC was measured to be 0.1%. Against T. rubrum and T. Mentagrophytes, both of which are athelete's foot inducing microorganisms, 83% of T. Mentagrophytes and 99.9% of T. rubrum were suppressed at 0.1% Unshiu oil, and the MIC were 0.3% and 0.05% respectively. Against S. aureus, a skin infection inducing bacteria, 103$cfu/m{\ell}$ of the bacteria were suppressed at 0.1% Unshiu Oil. Against B. subtilis, a non-pathogenic sporulating bacteria, 104$cfu/m{\ell}$ of the bacteria were suppressed at 0.1% Unshiu Oil. Against C. albicans, found in mucous membranes, 104$cfu/m{\ell}$ of the bacteria were suppressed at 0.1% Unshiu Oil. Against Aspergillus niger, an otomycosis inducing microorganism, 99.9% were suppressed at 0.1% Unshiu Oil. The results above indicate that low concentration of purified oil extracted from tangerine had strong antimicrobial activities against bacteria and fungi residing on the skin, and that it may be developed into skin disorder treating products in the future.

  • Paeonia lactiflora was stepwise extracted with hexane, chloroform, ethyl acetate, butanol and water. Anti-microbial activity of each extract was investigated. Methanol extract of P. lactiflora revealed anti-microbial activity against S. mutans, C. albicans, and S. aureus. Also, hexane fraction revealed anti-bacterial activity against S. mutans and ethyl acetate fraction acted as potent anti-microbial agent on C. albicans and S. aureus. The relative growth ratio(RGR) of hexane fraction of P. lactiflora against S. mutans were determined as 77.8% in concentration of 0.125 mg/ml, 98.46% in 0.25 mg/ml and 100% in 0.5 mg/ml. The ethyl acetate fraction of P. lactiflora revealed RGR against C. albicans as 52.5% in concentration of 0.125 mg/ml, 60.83% in 0.25 mg/ml and 78.33% in 0.5 mg/ml. It indicate that increasing concentration increase RGR. The measured minimal inhibitory concentration(MIC) of hexane fraction on S. mutans KCTC 5316 strain was 0.5 mg/ml and MIC of ethyl acetate fraction on C. albicans KCTC 7270 was 2.0 mg/ml. The experiment of inhibition to growth of KB roll(oral squamous cell carcinoma) result 61.9% in butanol, 76.7% in hexane extract of P. lactiflora. The hexane extract exhibit potent inhibition effect to the growth of KB cell. These results suggest that the hexane extract of Paeonia lactiflora has antimicrobial activity against S. mutans and has preventive effect to dental caries in addition to potent inhibition to KB cell growth.
