<p>PURPOSE:To obtain a fermentation product with a small amount of energy in high productivity, by fermenting a glucide raw material under a specific condition in a CO2 atmosphere, extracting the fermentation product with an extractant of CO2 under a specified condition and a separating it. CONSTITUTION:A glucide raw material is fermented in a CO2 atmosphere at >=critical pressure of CO2 and at >= critical temperature of CO2 to form an organic fermentation product (e.g., alcohol, acetone butanol, amino acid, organic acid, etc.,), which is extracted with an extractant of CO2 in a supercritical state in a fermentation tank, then pressure of the CO2 extracted solution is reduced to <= the critical pressure and it is separated into CO2 and the fermentation product to collect the aimed fermentation product.</p> |
