Abstract |
The purpose of this study is to use organisms or micro-organism functions for eco-friendly water-purification of cement bricks, utilizing bioremediation. Many researches have been performed in the past to improve water quality by using effective micro-organisms in construction materials. In order to purify water using micro-organisms, this research used soybean paste bacteria, an effective micro-organism that was identified through 16S rDNA sequence analysis performed in Daegu S. Environment Protection Institute in addition to Natto bacteria that was studied in the previous research. With these effective micro-organisms with water-purification ability, this study examined their water-purification possibility on cement bricks. This study used Zeolite to immobilize micro-organisms to bricks, and confirmed that the micro-organisms were attached on Zeolite from SEM analysis. The experimental results showed that specific micro-organisms can be used to effectively remove contamination an used to develop eco-friendly construction materials. The study on micro-organisms for material purification shows great promises as a future research topic.
