PROCEDURE FOR THE PRODUCTION OF POLYOLS BY PAO INDUSTRIAL SHOULD BE BASED ON THE FERMENTATION OF SOCKS. PATH STEES1401 S840829 MTEES1401 M841019

摘要

An industrial process for producing polyols comprises subjecting sugars to aerobic fermentation using Moniliella tomentosa var pollinis in a fermentation medium containing a water-soluble or water-dispersible polymer which is capable of retaining the cells in the fermentation medium. The process is especially suitable for the industrial production of erythritol and/or ribitol. The process overcomes the disadvantage shared by prior proposals wherein cells are lost from the fermentation media through being carried away by the foam produced during fermentation.
