Abstract:Immobilized microorganism is newly applied in bioremediation, which is high efficient, stabile and safe. Recently, it has been widely used in the purification of various polluted water, including the increasingly serious pollution of the offshore aquaculture water. This paper we first introduce the method of immobilized microorganism technology and the selection of carrier. Then we summarize the research advance in application of immobilized microorganism technology in the seriously polluted offshore aquaculture water. Finally we analyze the current problems existing in the application of the technology and discuss the future research needs.
