Biological reaction apparatus, biological reaction method, porous structure carrying aerobic or facultative anaerobic microorganisms used in biological reaction apparatus, and method for producing the porous structure

摘要

The biological reaction apparatus of the present invention and the biological reaction method using this biological reaction apparatus are efficient and economical for biological reactions using aerobic or facultative anaerobic microorganisms (hereinafter referred to as “aerobic microorganisms”). In order to achieve this, in the microorganism culture solution, a porous structure having a high loading density in which aerobic microorganisms are supported in advance to the depths of the pores before the biological reaction is present, and in the microorganism culture solution, micro-nano bubbles are present. Is included. Further, the porous structure carrying aerobic microorganisms of the present invention is one in which aerobic microorganisms are carried at a high loading density in advance before the biological reaction in order to perform the biological reaction efficiently and economically. It is. In addition, the method for producing a porous structure carrying aerobic microorganisms or the like of the present invention comprises a porous structure, aerobic microorganisms and micro-nano bubbles in order to carry aerobic microorganisms or the like at a high carrying density. The culture solution to be contained is brought into contact.
