<p>PURPOSE:To obtain immobilized bacterium having preferable characteristics such as shock loading resistance, acid and alkali resistance, starvation resistance, oxygen resistance, higher fatty acid resistance, etc., by immobilizing a microorganism to the interior of a crosslinked water-absorbing resin. CONSTITUTION:Water dispersion of a bacterium is blended with a water- absorbing resin while stirring, water containing the bacterium is absorbed in the resin, and added to a solution of a polyvalent metallic salt. Water-absorption ability of the resin is reduced by the presence of the polyvalent metallic ion to release water, crosslinking reaction of the resin with the polyvalent metallic ion is caused, the bacterium is embedded in the resin, to carry out immobilization. USE:Aerobic and unaerobic treatment in water treatment fields.</p> |
