To study Antimicrobial activities of wool and silk dyed by Impatiens balsamina extract with concentraion and times of dyeing, its leaf and stem was extracted by water. Wool and silk dyed by extracts were their microbial inhibition activities against Staphylococcus aureus KCTC 1928. The more concentration, The more times of dyeing their microbial inhibition activities were increased. Fabrics dyed by leaf estracts were higher microbial inhibition activities than fabrics dyed by stem extracts. Silk dyed by the leaf and stem extracts were higher microbial inhibition activities than wool dyed by the leaf and stem extracts. the more dye uptake, microbial inhibition activities of dyed fabrics were incresed.

본 연구는 고삼추출물과 황금추출물의 항균활성을 스킨케어화장품의 기본제형인 화장수, 로션에 적용, 관찰하여 식물유래의 천연항균제로써의 화장품에서의 방부시스템을 연구하였다. Test group에 고삼추출물 1%와 황금 추출물 1%, 0.5%씩의 고삼추출물과 황금추출물을 함유시켜 parabens와 imidazolidinyl urea가 함유된 positive control을 Escherichia coil, Pseudomonas aeruginosa, Staphylococcus aures, Candida albicans의 4가지 균에 대하여 실험하였다. 그 결과 고삼추출물과 황금추출물이 함유된 group은 control과 비교하여 4가지 균에 대하여 우수한 항균활성을 보였다. 고삼추출물과 황금추출물을 함께 사용하였을 때의 항균활성은 positive control과 비슷하게 나타나므로써 탁월한 항균활성을 보였다.

굴패각으로부터 제조된 굴패화석 비료 시용이 토양의 미시환경에 미치는 영향을 조사하기 위해 토양 내 microbial biomass 함량과 주요 토양효소의 활성을 조사하여 다음과 같은 결과를 얻었다. 굴패화석 시용량이 증가함에 따라 토양 내 microbial biomass C, N, P 함량이 크게 증가하였으며, 양분의 가급화와 관련 있는 주요 토양효소의 활성이 크게 증진되었다. 본 연구조건에서 굴패화석 시용에 따른 산성토양의 pH 개선은 microbial biomass P 함량 증진과 urease, ${\beta}$-glucosidase, alkaline phosphomonesterase의 활성증진에 직접적으로 영향을 주었으며, microbial biomass P와 phosphomonoesterase 활성증진은 유효인산 함량증진에 직접적으로 영향을 준 것으로 조사되었다. 결론적으로 약산성의 공시토양에 알카리성 제재인 굴패화석 시용은 토양생물과 효소 활성을 증대함으로써 작물생육에 필요한 양분공급 및 가용율 향상시키는 효과가 있는 것으로 평가되었다.

Soil enzyme and microbial activities are affected by fertilizer and compost applications and can be used as sensitive indicators of ecological stability. Microbial population and soil enzymes viz., dehydrogenase, urease, acid phosphatase and aryl-sulphatase were determined in the long-term fertilizer and compost applied paddy soil. Soil samples were collected from the four treatments (control, compost, NPK and compost+NPK). Long-term NPK+compost application significantly increased activities of urease, dehydrogenase and acid phosphatase than all other treatments. The compost application enhanced activities of urease, dehydrogenase and acid phosphatase than the NPK application. However, arylsulfatase activity was not significantly different between compost and fertilizer application. The highest microbial population was recorded in the NPK+compost treatment. The compost application also resulted in higher microbial population than the NPK application. The above results indicate that ecological stability could be maintained by application of compost alone or with NPK.

Phenylethanoids, including 2-phenylethanol, tyrosol, and salidroside are a group of phenolic compounds with a C6-C2 carbon skeleton synthesized by plants. Phenylethanoids display a variety of biological activities, including antibacterial, anticancer, anti-inflammatory, neuroprotective, and anti-asthmatic activities. Recently, successful microbial synthesis of phenylethanoids through metabolic engineering and synthetic biology approaches has been reported and could allow phenylethanoid production from alternative microbial sources. Here, we review the recent achievements in the synthesis of phenylethanoids by microorganisms. The work done so far will contribute to the production of diverse phenylethanoids using various microbial systems and facilitate exploration of further diverse biological activities of phenylethanoids.

본 연구에서 18종의 한약재추출물을 제조하여 병원성세균에 대한 한약재의 항균활성을 측정하였다. 오배자, 오미자 및 소목 메탄올 추출물은 대부분 균주에 대해 5 mg/mL 수준에서 항균활성을 나타냈으나 15여 종의 한약재추출물들은 30 mg/mL 수준에서 항균활성을 나타냈다. 오배자의 S. epidermidis와 Bor. bronchiseptica에 대한 최소저해농도는 0.6 mg/mL로 나타났다. 우수한 항균활성이 확인된 오배자, 소목, 오미자, 황금을 대상으로 극성이 다른 5가지 용매로 순차 분획하여 항균활성을 검토한 결과 대부분의 균주에서 EtOAc층이 다른 분획층에 비해 성장억제효과가 높게 나타났다. 항균력이 우수한 한약재추출물의 미생물 증식억제 효과를 조사하기 위해 증식배지에 0, 100, 300 및 500 ppm의 메탄올 추출물을 첨가하였다. 한약재 추출물을 첨가하지 않은 대조구에서는 12시간 이후 급격한 균의 성장을 나타내고 있으나 오배자와 소목추출물의 첨가 농도가 높을수록 그람 양성균인 S. aureus, S. epidermidis 및 L. monocytogenes는 뚜렷한 억제효과를 나타냈다. 오배자추출물은 그람음성균인 Sal. Pullorum과 Sal. Choleraesuis의 성장을 저해하였고 Bor. bronchiseptica, E. coli serotype $O_8$은 오배자와 소목추출물은 낮은 농도에서 성장이 다소 저해되었음을 보여주었고, 추출물의 농도가 높을수록 균의 성장이 강하게 억제되었다.

Methanol extracts of Perilla and Mugwort were stepwise extracted with hexane, chloroform, ethyl acetate, butanol and water. Anti-microbial activities and inhibitory effect on growth of oral tumor cell of each extract were investigated. Each extracts of Perilla and Mugwort were investigated to anti-microbial effects on oral microbes by means of agar diffusion method and MIC. These results suggest that the hexane extracts of Perilla and Mugwort have antimicrobial activities against S. mutans and potent inhibitory Effect to KB cell growth.

In this study, the effect of gamma irradiation on the microbial contamination and biological activities of tuna cooking juices was investigated. Tuna cooking juice was by-produced during the canning processing, and had various functional components. But, it was shown that the tuna cooking juice was seriously contaminated. Gamma irradiation effectively reduced the microbial population in tuna cooking juice. Also, 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity, tyrosinse inhibitory activity, and ACE inhibitory activity of tuna cooking juices were all increased as a result of gamma irradiation. These results suggest that wasted tuna cooking juices can be used as a functional component in the food and cosmetic industries if the irradiation technology were applied.

Seasonal and vertical variations of abiontic soil carboxymethylcellulase (CMCase) activities were assessed every other month for a year in two contrasting forest soils and evaluated the relationships between soil CMCase activity and environmental parameters. In climax deciduous soil, variations in CMCase activities caused by differences in sampling time were greater than those caused by differences in soil depth. On the other hand, counter phenomenon was obserned in coniferous soil at the stage of development. Correlation analyses showed that soil CMCase activities were significantly (p>0.01) correlated with microbial respiration rates ($O_2$ uptake) and all of the microbial population sizes. From these results, it is suggested that determination of abiontic soil CMCase activity is an useful additional index for evaluating the overall microbial growth and activity in soils.
