1. A method of enriching bacteria in a target soil capable of decomposing organic contaminants, the method comprising the step of:

  • mixing a fragmented porous material, said material having a number of micropores sufficient to provide a specific surface area greater than approximately 50 m2/g and smaller than approximately 600 m2/g and having a greater adsorptivity for absorbing said organic contaminants than said target soil, into said soil which said bacteria inhabit to form an enrichment soil layer; and

    circulating through said enrichment soil layer an inorganic salt medium containing carbon and nitrogen sources, said carbon and nitrogen sources being formed by only said organic contaminants to be decomposed, thereby enriching said bacteria in said fragmented porous material.
