Microcapsules with interconnected-spherical pores were prepared by in situ polymerization in a W/O/W emulsion system. Divinylbenzene and trimethylolpropane trimethacrylate were used as the wall material to prepare high strength microcapsules. The pore size and the diameter of the microcapsules increased with increasing NaCI concentration in the inner aqueous phase. The denitrification bacteria. Paracoccus denitrificans NBRC13301. was successfully immobilized in the porous microcapsule by a cocultivation of the bacteria and the microcapsules together. The denitrification bacteria immobilized in the porous microcapsule were able to decompose completely nitric acid and nitrous acid by a successive reaction.
