    摘要: Cultivation of microorganisms is controlled by measuring a pressure in a cultivation tank, a flow rate of effluent gas from the cultivation tank, and a concentration of carbon dioxide gas in the effluent gas, calculating a partial pressure of carbon dioxide gas in the cultivation tank and an amount of a carbon dioxide gas produced by the microorganisms, calculating an amount of propagated microorganism cells from the resulting partial pressure of carbon dioxide gas and the amount of produced carbon dioxide gas, thereby calculating an amount of microorganism cells in culture liquor, and supplying a substrate in an amount controlled in accordance with the resulting amount of microorganism cells in culture liquor.Microorganisms can be cultivated in high yield and at a high product concentration.
