Dyeing fastness and antibiosis effects of fabrics dyed with wormwood, which has been used in folk medicines and dietary life in Korea for a long time, were studied through dyeing small overcoats, which are used as diapers, with wormwood extract. As for the dying fastness test results, the fastness of decoloration was not that good but the pollution level showed a relatively positive result. As for the antibiosis effect results, the antibiosis of the dyed sample was better than the original sample on 3 kinds of bacteria, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and on 2 kinds of the fungi(Eumycetes). Aspergillus niger and Candida albicans. Especially, the sample that was mordant with CaCl2 and FeSO4·7H2O showed the best antibiosis effect. On the other hand, the sample that showed the best antibiosis effect was the refined fabric, which is a fabric that is not dyed.

The objection of this research is to conform of practicable possibility and recycling of producing junk after citrus fruits is processed. In the middle of practicable possibility, with verification of antibiosis that tactiling sensibility in a microorganism. With extracting d-limonene oil that have 70${\sim}$90% a component of oil out of junk citrus peel, making certain the about 12000ppm(1.2%) concentration of it. By means of antibiosis property over the a pathogenic bacterium as well as a residence bacterium, considerating the limit of application against daily living supplies needs to antibiosis. Antibiosis effect of a stationing bacterium in the body permanently and by means of antibiosis verification of special bacteria Propionibacterium Acnes that causative skin trouble is selected, in based the antibiotic sencitivity test check up result of minimal inhibitory concentration(MIC).

The purpose of this study was to identify the utility value with material of natural dyeing and to examine the dyeability and antibiosis of fabrics dyed with Solanum nigrum extract. The results obtained are as follows. First, the color tone of dyed fabrics was tinged with from yellow series to green series, in the chrominance the fabric dyed with Fe mordant was showed the highest value. Second, colorfastness to dyeing showed difference as to mordants, but colorfastness to dyeing except for sunlight colorfastness showed the good colorfastness result on the whole. Third, in the test results of antibiosis, the dyed both cotton and silk fabrics showed the very excellent antibiosis effect for bacteria but showed the insignificant effect for fungus.

Rice straw liquid was prepared from rice straw using simple pyrolysis furnace, and its effects on plant growth and antibiosis were investigated. Effects of straw liquid on plant growth of Oryza sativa L., Glycine max Merr. and Lactuca sativa L. and antibiosis of bacteria and mold of rice straw liquid were studied. Th rice straw liquid showed good results on plant growth and multiplication. Rice straw liquid showed a little antibiosis on bacteria but non antibiosis on mold. Rice straw liquid had minimal inhibitory concentration of 2.5-5% for bacteria.

The aim of study was to elucidate the antibiosis of the Sophora Radix extracts by ethanol solvent on bacterias. The antibiosis on bacterias was examined in moisture water included the Sophora Radix extract. The results are as follows; Minimum inhibitory concentration (MIC) of Sopora Radix extracts showed markedly lower on gram positive bacterias($0.0125{\sim}0.025$) such as aureus, B. subtilis, S. epidermids than that on gram negative bacterias such as E. coli, P. aeruginosa(>10). The MIC of moisture water included the Sophora Radiix which extracted by ethanol solvent was very low which meaned good antibiosis($0.0063{\sim}0.5$). The antibiosis of moisture water included the Sophora Radiix was improved by adding the ethanol on some baterias. In conclusion, Sophora Radix had excellent antibacterial effect. Therefore, it is expected that Sophora Radix can be practically used as the natural material of functional cosmetics for preventing the Bacterial inhibitory in skin.

In order to elucidate roles of lactic acid bacteria(LAB) for the antibiosis occurring in th fermenting environment of Kimchi, 2.052 strains of LAB were isolated from Kimchi. Fifty tow strains which showed antagonistic effect against 4 indicator strains were finally selected and investigated. Based upon responses to protease treatment, antibiosis of the 52 strains of LAB were classified into 3 types. Type A antibiosis resulted from action of antibiotic-like substances which were not affected by protease treatment and which had broad action spectra against even natural inhabitants of Kimchi. Type B antibiosis was due to bacteriocin-like substances which were very sensitive to treatment of protease and more effective against foreign bacteria than original inhabitant microflora. Type C antibiosis was owing to proteinaceous compounds which were activated or induced by the presence of protease and then exerted antibacterial activities. Therefore, lactic acid bacteria appeared to contribute to antibiosis of Kimchi by the concerted action of these three different types of antibacterial compounds. As one of model system for type B bacteriocin, the antagonistic compound produced by LAB31-9 as well as th producer strain itself was further charaacterized. Strain LAB31-9 was identified as L. casei. Bacteriocin produced by LAB31-9 was proteinaceous and stable over wide range of pH and to various solvents, but very labile to heat treatment. Its mode of action was bactericidal. Based upon these data, bacteriocin produced by LAB31-9 was named as 'caseicin K319'. Genetic determinant for the bacteriocin production of LAB31-9 was located in the chromosome.

To separate anticaries and antiinflammation from Aloe vera peel, we investigated a inhibited effect of Streptococcus mutans JC-2 that was antibiosis, glucosyltransferase activity about aloe-emodin and barbaloin. Aloe-emodin and barbaloin had strong antibiosis activity against Streptococcus mutans JC-2, they were especially antibiosis effect to low growth and prolong lag phase at attachment concentration 100$\mu\textrm{g}$/mL. The reduction rate of a culture fluid became to lessen than the comparison group for aloe-emodin and barbaloin. The intracellular materials of Streptococcus mutans JC-2 were to leakage as much as attachment concentration addition of aloe-emodin and barbaloin but there was no significant difference membrane demage between two active substances. The activity of GTase was inhibited by aloe-emodin and barbaloin and their inhibition rate was respectively 99.8%, 98.4% at the attachment concentration 100$\mu\textrm{g}$/mL.

Having silk dyed with some pigment extracted from the skin of an onion, examined the change of color by time and frequency of dyeing and a mordanted cloth, and the antibiosis of a dyed cloth and a mordanted cloth. The result of this were as follows ; 1. The pigment of an onion was easily extracted in the hot water of $40^{\circ}C$ and much more extracted as the temperature of water rises($70^{\circ}C$). 2. As a result of dyeing it by the change of time, 30minutes, 60minutes, 90minutes and the frequency of dyeing, once, twice, three times after filtering the extracted solution, the one dyed three times for 30minutes was the best. 3. The difference of color of a mordanted cloth was the highest in the mordant of $SnCl_2\;2H_2O$ on the basis of the value of L of the non-mordant dyed three times. 4. The mordant of copper sulfate was proved to have the highest antibiosis in the antibiosis of a dyed cloth and a mordanted cloth, and it was proved that the pigment of the skin of an onion had excellent antibiosis.

본 연구는 아유르베다의 모발과 두피 프로그램을 적용하고 그 효과를 분석하고자 한다. 아유르베딕(Ayurvedic) 처치는 자연치유력에 의해 면역력을 강화시킨다. 아유르베딕 베이스 오일과 에센셜 오일을 모발과 두피에 사용했을 때, 두피에 상주하는 균에 대한 항균효과를 알아보기 위해 MIC test 와 Halo test를 통해 측정하였다. 그 결과는 다음과 같다. 9종류의 베이스 오일과 18종류의 에센셜 오일을 이용하여 Bacillus subtilis, Propionibacterium acnes균에 대한 베이스 오일과 에센셜 오일의 항균효과를 MIC test를 통해 조사하였다. 실험 결과, 베이스 오일에서는 모두 균에 대한 항균효과가 없는 것으로 나타났으며, 에센셜 오일은 Chamomile, Clary sage, Jasmine, Neroli, Rose오일에서 두 균에 대해 모두 5% 이하에서 항균효과가 없는 것으로 나타났다. 두 균주에 대해 Thyme, Geranium, Lavender, Tea tree가 모두 효과가 높은 것으로 조사되었다. Geranium, Lavender, Thyme 에센셜 오일과 Sesame and Coconut 베이스 오일을 이용하여 7가지 공시균주에 대한 Halo test결과 베이스 오일에서는 항균효과가 없는 것으로 나타났다. 에센셜 오일은 7가지 공시균주에 대해 모두 항균성이 있는 것으로 조사되었다. Thyme은 MIC test 와 Halo test 결과 항균력이 가장 높은 것으로 나타났다.
