The purpose of this paper is to decide the ratio mixture between microbes and the most suitable material in order to immobilize white rot fungus. It shows that white rot fungus favorably lives, regarding to respiration speed and activity when pellet is immobilized by PVA. In addition, it survives better with sodium alginate, concerning about the rate of swelling. When PVA-frozen method is applied, methylene blue is decolorized 100% by immobilized Trametes versicolor and 90% by immobilized Irpex lacteus after 44hr. As a result, pellet immobilized by PVA, which indicates better mechanical stability and declororization rate, is superior to sodium alginate. The mixture rate between microorganisms and PVA is 1:1.
