PROBLEM TO BE SOLVED: To provide an efficient culture method of microorganisms (particularly, a liquid culture method by liquid culture medium) in which a culture facility is simple, and has less risk of contamination.SOLUTION: In culturing microorganisms (except strictly anaerobic microorganisms) by a liquid culture medium in a fermentation tank, culture solution in the fermentation tank is circulated by a diaphragm pump during culture, aeration is performed by a microbubble generator during the circulation, by which microorganisms (yeast, lactic acid bacteria, for example) maintaining high survival rate and activity can be simply and efficiently cultured (proliferated). |
