PURPOSE:To reduce the volume of oxygen to be supplied without reducing the amount of a useful substance produced, by providing an anode in a culture fluid, applying a voltage capable of oxidizing the components of the respiratory system of the microorganism to carry out cultivation. CONSTITUTION:An anode (working electrode) is provided in a culture fluid of an aerobic microorganism, e.g. aerobic bacterium, actinomyces, yeast, mold or basidiomycete, and a voltage is applied through a cathode (counter electrode) for passing through a current or a standard electrode to be a potential standard to the anode. The potential to be applied to the anode is a potential sufficient to oxidize an electron carrier of the respiratory system held by the microorganism to be cultivated, i.e. cytochrome, and is preferably such a potential as not cause the decomposition of water. |
