Abstract

Air and soil are being contaminated by the environmental pollution as a result of climate change and urbanization, resulting in water pollution reaching serious levels. In this studies, we investigated the use of antimicrobial copper for the removal of biological pollutants from water system. Specifically, we tested its effects against E. coli, B. subtilis, S. aureus, K. pneumoniae and P. aeruginosa. Made a sphere shape having a diameter of 2cm using a strip-shaped copper wire of 0.5g, 1g and 2g. And then, to confirm the antimicrobial activities, each copper ball was equipped in the broth which inoculated each pathogens. The results showed that bacterial growth of the five test bacteria was inhibited by more than 99% after reaction with a 0.5 g copper ball for at least 20 minutes. Based on the these results, if perform the further experiment such cytotoxicity, it is expected that will be enough to be used as a filter for water quality purification. The developed technique is expected to be widely applied in various industries.

기후변화와 도시화에 따른 오염으로 인하여 대기 및 토양이 오염되었고, 이들 오염물질이 점오염원과 비점오염원을 통하여 수질 내로 흘러 들어가면서 수질오염이 심각한 수준에 이르렀다. 이러한 수질 내 생물학적 오염원 제거를 위하여 간편하면서도 효율이 높은 수질 정화용 필터의 개발이 요구되는 실정이며, 이를 위하여 항균력을 가지고 있는 구리를 이용하여 연구를 진행하였다. 본 연구에서는 수질오염의 기준으로 사용되는 대장균 외 주요 병원성 균 4종 (Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa)을 사용하였으며, 스트립 형태의 구리선 0.5g, 1g, 2g을 이용하여 직경 2cm의 구 형태로 제작하였다. 항균력 확인을 위하여 각 병원성 균을 접종한 후 구리공을 장착한 다음, 99% 이상의 항균력을 가지는 조건을 조사하였다. 연구 결과 0.5g의 구리선으로 만든 구리 공을 최소 20분간 반응시켰을 때 5종의 병원성균에 대해서 99% 이상의 생장 억제능이 나타나는 것을 확인하였다. 본 연구 결과를 바탕으로 세포 실험 등의 추가 실험이 진행된다면 수질 정화용 필터로 사용되기에 충분할 것으로 판단되며, 이를 통해 공장 및 도시 폐수 뿐만 아니라 축산 및 양식 산업 분야에 광범위하게 적용될 수 있을 것으로 기대된다.
