A heavy metal adsorbent composition containing bacterial cells which are obtained by acid-treating a bacterium selected from among Bacillus sp. KRI-02 and its analogs, Bacillus licheniformis and Staphylococcus sp. KRI-04 and its analogs; and a method of removing a heavy metal from a heavy metal-containing medium with the use of the composition. Thus, heavy metals can be removed from rivers, lakes, ponds, industrial waste waters, etc.
