| abstract | PURPOSE:To improve the microbial cell production efficiency of yeast, by controlling properly the flow addition rate of a substrate in cultivation. CONSTITUTION:A seed yeast is put into a cultivation tank 1, and a substrate is fed from a substrate tank 7 thereinto by a substrate feed pump 8. Data from an inlet oxygen partial pressure measuring instrument 5, inlet gas flow rate measuring instrument 6, oxygen partial pressure measuring instrument 11 of the outlet gas, gaseous carbon dioxide partial pressure measuring instrument 12 and waste gas flow rate measuring instrument 13 are input to a controlling electronic computer 4 to calculate the amount of yeast cells in the tank 1 from the multiplication model calculation based on the oxygen balance, carbon balance and substrate feed rate. The substrate flow addition rate is then obtained by considering the alpha value (substrate flow addition rate based on the amount of yeast cell), and the substrate feed pump 8 is operated according to the rate. The respiratory quotient (RQ) and ratio of the outlet gas flow rate to the inlet gas flow rate (beta value) are obtained, and the alpha value is changed according to the values to control the substrate feed rate. |
