Heavy metal in soil shows negative effect on ecosystem by suppressing the growth of plants and damaging soil ecosystem. However, checking the heavy metal content in soil requires too much time and money. This research was conducted in order to check these problems and understand the existence of heavy metal contained in soil efficiently. Unlike regular soil bacteria, ahms- bacteria (anti- heavy metal soil bacteria), separated from soil contaminated with heavy metal, is able to survive in soil containing heavy metal. Moreover, it can survive in pH5 and 40℃, the environment where the growth of regular soil bacteria shows drastic decrease. The reason of this strong surviving ability of ahms-bacteria was found to be its sulfate reducing function. Ahms-bacteria produces hydrogen sulfide, and this hydrogen sulfide, creates precipitate by the reaction with heavy metal in soil. This was used to offer simple but accurate method to sort out soil contaminated by heavy metal. In fact, when the experiment was conducted with contaminated soil, it was checked that ahms-bacteria was able to be the standard of heavy metal-contaminated soil.
