<p>PURPOSE:To prevent marine denitrifying bacteria from flowing out and to secure a stable denitrification function through a long period of time by immobilizing microorganisms having a function to reduce nitrate or nitrite into gaseous nitrogen in sea water in a water vessel for culture, etc., on polymer. CONSTITUTION:A marine denitrifying bacteria immobilizing material for removing nitrogen in sea water which causes eutrophication is made by immobilizing microorganisms having a function to reduce nitrate or nitrite into gaseous nitrogen in natural or artificial sea water (hereafter called as marine denitrification bacteria) on polymer gel. As a polymer material used for the inclusively immobilized material is selected preferably from polyvinyl alcohol, polyethylene glycol, and polyacrylamide. The shape of the polymer gel is selected from sphere, cube, fiber, sheet, and tube; the gel is molded according to the purpose of application.</p> |
