This invention provides an interface bioreactor system comprising (a) a reaction tank having (1) a reaction solvent placed therein, (2) a plurality of plate-like hydrophilic immobilizing carriers each having a thickness of 1 to 500 mm and packed therein so as to be arranged in a vertical position at intervals of 3 to 100 mm, the hydrophilic immobilizing carriers having a microorganism deposited and immobilized on the surfaces thereof in a growable or viable state and containing a liquid medium composed of water and nutrients necessary for the growth or survival of the microorganism, and (3) a sparger or agitator disposed at the bottom thereof; and (b) an aeration line connected with the reaction tank for supplying oxygen thereto. This system is highly efficient and can be scaled up easily.
An interface bioreactor system comprising (a) a reaction tank having (1) a reaction solvent placed therein, (2) a plurality of plate-like hydrophilic immobilizing carriers each-having a thickness of 1 to 500 mm and packed therein so as to be arranged in a vertical position at intervals of 3 to 100 mm, said hydrophilic immobilizing carriers having a microorganism deposited and immobilized on the surfaces thereof in a growable or viable state and containing a liquid medium composed of water and nutrients necessary for the growth or survival of the microorganism, and (3) a sparger or agitator disposed at the bottom thereof;
A process as claimed in 7 wherein said plate-like hydrophilic immobilizing carriers are regenerated for repeated uses by washing said plate-like hydrophilic immobilizing carriers after each use and replacing the aqueous phase present therein by a fresh liquid medium.
