Abstract

This study focused on the development of a fundamental technology for coating of concrete surface using slime produced from bacteria. To assign self-purification ability and improve durability performance of concrete, Rhodobater capsulatus that generates slime were selected and absorption technology for the selected bacteria was then examined. From the production of slime and growth activity of the bacteria, the optimum medium for Rhodobater capsulatus can be recommended as maltose. Furthermore, image analysis showed that high porous resin powder is more effective for absorption of the Rhodobater capsulatus than the other materials tested.

본 연구에서는 박테리아를 활용하여 콘크리트 구조체를 코팅할 수 있는 기초 기술을 개발하는데 중점을 두었다. 박테리아의 자기정화 능력과 함께 콘크리트 내구성 향상을 함께 도모하기 위하여 슬라임 막을 형성하는 박테리아(Rhodobater capsulatus)를 선정하고 이를 흡착하기 위한 기술을 제시하였다. Rhodobater capsulatus의 배지별 슬라임 생성량 및 생장속도 평가결과로부터 최적의 배지조건은 maltose로 평가되었다. 제시된 배지를 기반으로 배양된 Rhodobater capsulatus의 고정화를 위해 흡착제를 활용하였으며 이를 image analysis 통해 흡착특성을 평가하였다. Rhodobater capsulatus 흡착을 위해서는 고 다공성 수지가 추천될 수 있었다.
