An anaerobic bacterium culture device equipped with a mechanism for containing fine bubbles and ultrafine bubbles of a gas containing nitrogen gas as a main component in a culture solution, and an anaerobic bacterium culture method using this anaerobic bacterium culture device.

摘要

PROBLEM TO BE SOLVED: To efficiently reduce the dissolved oxygen concentration of a culture solution before the start of culturing, and to continuously maintain a low dissolved oxygen concentration of an anaerobic bacterium culture solution even during culturing, thereby culturing anaerobic bacteria. Provide an anaerobic bacterium culturing apparatus and an anaerobic bacterium culturing method capable of economically and efficiently performing the above. SOLUTION: In an anaerobic bacterium culture apparatus in which a culture solution 1 and an anaerobic bacterium are housed in a culture tank 2 and the anaerobic bacterium is cultivated, the culture solution contains 90% by volume or more of nitrogen gas. An anaerobic bacterium culture apparatus comprising a mechanism (I) for containing bubbles and ultrafine bubbles. [Selection diagram] Fig. 3
