Adsorption Technology for Bacteria-Based Concrete Coating

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.
