Preparation of methyl ursodeoxycholate in an interface bioreactor: use of a mixed solvent system to increase the solubilities of substrate and product.
A mixed solvent system was used as the reaction solvent of an interface bioreactor for the first time. The solvent, dodecane/2-ethylhexyl acetate (4:6), exhibited excellent efficiency in the preparation of methyl ursodeoxycholate with Eubacterium aerofaciens JCM 7790.
