Abstract:
Conditions for biotransformation and purification of FUR were investigated. The result showed that when the cell concentration of E. aerogenes was 10% (w/v), the temperature and pH were 7.8 and 60 degrees C respectively, 59.7% UR was converted to FUR. It also demonstrated that the ideal procedure for the purification of FUR is silica gel column chromatography by two elution systems (S1:CHCl3:CH3OH:H2O = 61:13:1, and S2; CH3COOCH2CH3:CH3OH:CH3COOH:H2O = 12:3:3:2) with the purity and yield of 98.0% and 86.0% respectively.
