실내식물 9종의 근권부 하이드볼 배지에서 배양된 세균집단이 공기중 벤젠과 같은 휘발성 유기화합물의 제거효과에 미치는 영향이 조사되었다. 여러 식물 근권부의 배양토에서 배양된 세균 집단은 벤젠을 제거할 수 있었는데, $Spathiphyllum$ $wallisii$ Regel, $Pachira$ $aquatica$, $Ficus$ $elastica$, $Dieffenbachia$ sp. 'Marrianne' Hort., $Chamaedorea$ $elegans$ 식물들은 벤젠의 초기농도를 1.000으로 기준하였을 때, 세균 집단이 전혀 없는 배지의 대조구 초기 농도 대비 잔류율이 0.596이었으나 상기 언급한 식물들은 0.741-1.000으로서 벤젠의 농도를 현저히 감소시켰다(LSD, $P$=0.05). 이와 같은 경향은 식물의 종류에 따라 차이는 있었지만 톨루엔의 경우에도 비슷하게 나타났다. 이러한 결과를 바탕으로 $P.$ $aquatic$ 근권부의 배양토로부터 배양된 세균 집단을 $P.$ $aquatica$, $F.$ $elastica$, $S.$ $podophyllum$에 접종하였을 때 접종하지 않은 식물들에 비하여 벤젠과 톨루엔을 현저히 제거하는 효과가 나타나, 근권부의 미생물 집단을 이용하여 공기 중 휘발성 유기화합물(VOC)을 제거할 수 있음을 보여 주었다.

본 연구에서는 인체 내 장내 세균 및 병원성 식중독 세균에 선인장 추출물이 미치는 영향과 항산화, 항고혈압 활성에 대하여 분석하였다. 항균활성은 96well-plate법과 paper disc법을 이용하여 실험하였으며 줄기 추출물의 경우 96well-plate 및 paper disc법의 결과, 장내유해균인 Eubacterium limosum 및 Clostridium perfringens, C. butyricum, C. difficile과 Staphylococcus aureus에 대하여 높은 억제율을 보였으나 Bacteroides fragilis, Bifidobacterium bifidum, Lactobacillus acidophilis, Streptococcus thermophilus의 경우 억제율을 나타내지 않았다. 열매 추출물의 경우 장내유해균 및 장내유익균에 Bacteroides fragilis, Bifidobacterium bifidum, Lactobacillus acidophilis, and Streptococcus thermophilis에 대하여 억제율을 나타내지 않았다. 또한 줄기 추출물의 경우 열 및 pH에서도 장내미생물에 대한 항균활성에 안정함을 나타내었다. 선인장 추출물의 폴리페놀과 플라보노이드 함량 및 DPPH 전자공여능을 측정한 결과 열처리하지 않은 열매와 줄기 추출물의 폴리페놀은 3.02 mg/g, 5.85 mg/g, 플라보노이드는 1.04 mg/g, 2.1 mg/g, 전자공여능은 87, 88%로 높은 수율을 나타내었다. 선인장 추출물의 항고혈압활성은 줄기 추출물의 경우 88.8% 열매 추출물의 경우 69.2%의 항고혈압활성을 보였으며 상기 결과를 종합할 때, 선인장 줄기추출물은 장내 유해균의 억제 및 유익균의 증진을 통한 장내 균총 개선을 위한 기능성 식품소재로 활용할 수 있다고 판단된다.

Opuntia ficus-indicavar. saboten Makino (Cactaceae) is a tropical or subtropical plant that has been widely used as folk medicine for the treatment of diabetes, asthma, burn, edema and gastritis. The purposes of the present study were to identify antioxidant constituents from fruits and stems of the plant cultivated in Cheju island, Korea, and examine their in vitro neuroprotective activities. Using a chromatographic fractionation method, ten chemical constituents were isolated from ethyl acetate extracts. By means of chemical and spectroscopic methods, those were identified as eight flavonoids such as kaempherol (a), quercetin (b), kaempferol 3-methyl ether (c), quercetin 3-methyl ether (d), narcissin (e), dihydrokaernpferol (f), dihydroquercetin (g) and erioclictyol (h), and two terpenoids such as 3-oxo-${\alpha}$-ionol-${\beta}$-d-glucopyranoside (i) and roseoside (j). Among the isolated compounds, comrounds c~e and h~j were those reported for the first titre from the plant. Compounds b, d and g showed DPPH free radical scavenging activities with IC$\sub$50/ values of 28, 19 and 31, ${\mu}$M respectively. Compounds d and g also inhibited iron-dependent lipid peroxidation with IC$\sub$50/ values of 2.4 and 3.5 ${\mu}$M. In a primary rat cortical neuronal cell culture system, compounds b, d and g inhibited xanthine/xanthine oxidase-induced (IC$\sub$50/ values of 18.2, 2.1 and 54.6 ${\mu}$M) and H$_2$O$_2$-induced (IC$\sub$50/ values of 13.6, 1.9 and 25.7 ${\mu}$M) cytotoxicities. In addition, compounds d and g inhibited NMDA-induced excitotoxicity by 21 and 33%, and only compound d inhibited growth factor withdrawal-induced apoptosis by 31% at a tested concentration of 3 ${\mu}$M. The results suggest that the antioxidant constituents with in vitroneuroprotective activities may serve as lead chemicals for the development of neuroprotective agent.

In fresh water fish hatcheries and farms, Saprolegniales often cause serious mortality to the fish and their eggs. Malachite green is an effective antifungal agent, but is carcinogenic to fish and humans. Alternative antifungal agents are needed. Presently, we tested various concentrations of MBT-01108 (Opuntia ficus-indica extracts) alone and in combination with bronopol, formalin and sodium chloride (MBT-01108 mixture) on in vitro mycelial growth and in vivo remediation of adult eel, Anguilla japonica, infected with Saprolegnia sp. and fertilized eggs of chum salmon, Oncorhynchus keta, to evaluate the compounds' antifungal efficacy on eyed-egg and hatching rates. MBT-Oll08 mixtures incorporating bronopol and formalin at respective concentrations of 50 and 30 parts per million (ppm), and 100 and 20 ppm were most effective in controlling Saprolegnia in vitro and in vivo (P<0.05). Repeated daily exposures to 50 ppm and 100 ppm MBT-01108 were more effective than exposure every 2-3 days post-fertilization for the inhibition of Saprolegnia infection of rainbow trout, Oncorhynchus mykiss eggs as compared with control (0 ppm).

A method for the process of making fig conserves to prevent the denaturation of ficin (EC3.422.3) that is a proteolytic enzyme in fig (Fixus carica L. ) has been developed. The suutable composition ratio of materials such as, fig, sugar, citric acid and potassium sorbate, to make fig conserves was 1,000, 600 , 1.0 and 0.67g , respectively. to maintain the ficin activity, it was necessary that these materials were heated on 55$^{\circ}C$ and concentrated in the reduced pressure. At a result of sensory evaluation , meat treated with fig was the softest among samples. Then the treated beef with 55$^{\circ}C$ converse, 7$0^{\circ}C$ conserves, sugar and control have been shown the decreased rate respectively. There was significantly different in the effect of tenderness between each group(0.1%) . The nitrogen content of connective tissue was relatively low in the groups of the treated beef with fig and 55$^{\circ}C$ converses, 7$0^{\circ}C$ converses sugar and control , which was similar to the order of the ficin activity. This research revealed that the constituent protein of meat muscle was decomposed by ficin and its solubility was relatively higher than before.

In order to study the tenderizing effect of the proteolytic enzyme, ficin, from fig fruit (Ficus carica L), the enzyme was purified from fig latex by precipitation and chromatography. The ficin separated from Bongraesi showed single band on SDS-PAGE. However, the ficin from Masui showed tow bands. The specific activity of ficin purified from Bongraesi species was 2.8 unit/mg protein and that from Masui species was 6.5 unit / mg protein. The amounts of ficin purified from 50 mL of crude latex of Bongraesi and Masui were 1,760 mg and 657 mg, respectively. the water holding capacity of beef decreased to the large extent, when sugar Bongraesi latex and Masui latex were added. The hardness of beef showed decreasing tendency with the time, however, after 60 min, it decreased and thereafter increased a little after 120 min. the hardness of beef decreased sharply with addition of the latex of Bongraesi and Masui. The Masui has more tenderizing effect than the Bongraesi. When meat was mixed with tenderizing agent(ficin) and not heated, the change of color showed significant difference (p＜0.01). when meat was mixed with tenderizing agent(ficin) and heated, the toughness showed significant difference (p＜0.01) and the softness showed significant difference (p＜0.001).

Five bacterial strains designated DY37, BS333, JJ521, BM1, and DG13-2 were assigned to the genus Deinococcus were isolated from forest soil samples collected from Deogyusan, Busan, Changwon, and Seoul of South Korea. The isolates were Gram-staining negative or positive, and pale pink- or red-pigmented, short-rod shaped. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strains DY37, BS333, JJ521, BM1, and DG13-2 were most closely related to Deinococcus aquatilis CCM $7524^T$ (with 99.0% similarity), D. ficus CC-FR2-$10^T$ (100.0%), D. grandis KS $0485^T$ (99.2%), D. roseus TDMA-$uv51^T$ (98.9%), and D. yunweiensis $YIM007^T$(100.0%), respectively. These 5 species have never been proposed in Korea; therefore 5 species of 1 genera in the family Deinococcaceae in the order Deinococcales within the class Deinococci are reported for proteobacterial species found in Korea.

Soil and root samples were collected form the rhizoshpere of 11 different medicinal plants to determine the incidence, density and identification of root-knot nematode species associated with medicinal herbs. About 55% of medicinal herbs examined was found to be infested with root-knot nematodes. As a result of infection casued by three root-knot nematodes, M. hapla recorded 43.3% in medicinal herba whereas M. incognita and M. arenaria showed 7.9% and 3.7%, repectively. Forsythia koreana, Hemerocalis fulva, Hibuscus mutabilis and Petasites japonicus were the most severely infested herbs whereas Acanthopanax sessilflorus was least infested. Population of the second stage younger plants. Meloidogyne hapla, M. incognita and M. arenaria were the species associated with the medicinal herbs. The most abundant nematode observed in medicinal herbs was M. hapla and followed by M. incognita and M. arenaria. M. arenaria was observed firstly on Ficus carica, one of medicinal plant.
