Abstract
The invention relates to a microorganism, obtained by treatingKCCM 10488 producing 5'-Xanthylic acid as parent strain with UV radiation and mutation Derivatives such as N-methyl-N′nitro-N-nitrosoguanidine (NTG), Having a resistance to 5-fluorotryptophan which enhances Biosynthesis of N5-N10-tetrahydrofolate used for transferring Two formyl group during the process of puring biosynthesis, making It possible to accumulate 5′xanthylic acid in culture medium at a high Yield and high concentration rate same period of fermentation.
