FERMENTATION PROCESS AT REDUCED PRESSURE |
摘要 |
A fermentation process includes contacting a carbohydrate source with a microorganism in an aqueous fermentation broth to form a fermentation product which is a salt or a product with a boiling point above the boiling point of water. The fermentation process is carried out at a pressure which is below atmospheric pressure and at least at the value where the reaction medium is at its boiling point at the fermentation temperature. Water is evaporated and removed from the reactor during the fermentation in an amount which is at least 20% of the volume of liquid present in the reactor at the start of the fermentation. A fermentation process at reduced pressure while removing a substantial amount of water removes a surplus of water in the system, ensures removal of reaction heat, and may lead to improved fermentation quality. |
