Abstract：
 The invention discloses white rot fungus immobilization method used to restrain hetero fungus growth under non sterilization environment in microorganism application field. It includes the following steps: using Phanerochete chrysosporium as white rot fungus based on bacterium growth restraining liquid medium; selecting out inert support-isocyanurate foam vector by orthogonal experiment; using the isocyanurate foam as two triangular prisms; processing immobilization for white rot fungus by adding isocyanurate foam vector into liquid medium; utilizing isocyanurate foam inherent structure feature and combining with bacterium growth restraining liquid medium. By competitive experiment, it is not infected by other hetero bacterium; and it gain stable decoloration rate in activated dye degradation phase; and the decoloration rate can reach above 95%. The result is same with sterilization environment. The invention has the advantages of convenient using, low material price, and good hetero bacterium restraining effect; and it reduces the running cost caused by sterilization condition.
