Process for producing 5-methyluridine and purification by sedimentation velocity |
摘要 |
The present provides a process for obtaining high-purity 5-methyluridine crystals from nucleic acid ingredients as starting materials using a microorganism. The process comprises culturing a microorganism, removing part or the whole of the culture medium ingredients, conducting the enzyme reaction by the microorganism, crystallizing 5-methyluridine formed, and separating the obtained crystals from other impurity crystals on the basis of a difference in the precipitation rate.
