BIOLOGICAL REACTION DEVICE, BIOLOGICAL REACTION METHOD, AEROBIC MICROORGANISM-CARRYING POROUS STRUCTURE TO BE USED IN BIOLOGICAL REACTION DEVICE AND METHOD FOR PRODUCING POROUS STRUCTURE

摘要

The biological reaction device according to the present invention and the biological reaction method using the biological reaction device address the problem of more efficiently utilizing micronanobubbles and thus efficiently and economically performing a biological reaction using an aerobic microorganism. The aerobic microorganism-carrying porous structure according to the present invention and the method for producing the porous structure address the problem of providing a porous structure to be used in a biological reaction device or biological reaction method, said porous structure enabling efficient and economic performance of a biological reaction, and a method for producing the porous structure.To solve these problems, the biological reaction device according to the present invention and the biological reaction method using the biological reaction device are characterized in that a porous structure, which carries an aerobic microorganism deeply in pores thereof at a high carrying density, is disposed in a liquid culture medium for microorganism and, at the same time, the liquid culture medium for microorganism contains micronanobubbles. The aerobic microorganism-carrying porous structure according to the present invention is characterized by carrying an aerobic microorganism at a high carrying density. The method for producing the porous structure is characterized by comprising contacting a porous structure with a liquid culture medium that contains an aerobic microorganism and micronanobubbles.
