(US5714058-A)      Microorganisms are applied on a material to be treated contg. a pollutant. The material is maintained in anaerobic atmosphere. By irradiating the material with light and electromagnetic waves, the microorganisms are activated. Physical index data of the material is measured and based on the physical index data, irradiation with light and electromagnetic wave and an anaerobic level of anaerobic atmosphere are controlled. Pollutant is converted into an organic substance, utilized by animals and vegetables, through acceleration of mainly anaerobic fermentation decomposition and photosynthesis.    ADVANTAGE -   Activation of environment organic is rapidly achieved.    (JP2949211-B2)      Microorganisms are applied on a material to be treated contg. a pollutant.
