MICROORGANISM CULTURE METHOD AND CULTURE DEVICE

摘要

The present invention makes it possible to stably culture gas-assimilating microorganisms regardless of variations in the supply flow rate of a substrate gas. Gas-assimilating microorganisms 3 are cultured in a culture medium 2 in a culture tank 10. A substrate gas including CO, H2 and the like is supplied to the culture tank 10 and is dissolved in the culture medium 2. When the supply flow rate of the substrate gas or a prescribed component thereof to the culture tank 10 reaches a prescribed value or below, the culture medium 2a is rapidly discharged from the culture tank 10.
