Abstract
The invention relates to Corynebacterium ammoniagenes CJXOL 0201 KCCM 10447 producing 5'-xanthylic acid. More specifically, the invention relates to Corynebacterium ammoniagenes CJXOL 0201 KCCM 10447 which is a mutant strain of Corynebacterium ammoniagenes KCCM 10340 having a resistance to oligomycin. In order to obtain mutant strain having enhanced respiratory activity, the present invention adopted Corynebacterium ammoniagenes KCCM 10340 as parent strain and treated it with UV radiation and mutation derivatives such as N-methyl-N'-nitro-n-nitrosoguanidine(NTG) according to ordinary procedure. Therefore, Corynebacterium ammoniagenes CJXOL 0201 KCCM 10447 of the present invention makes it possible to increase ATP reproducing activity for same period of fermentation and can accumulate 5'xanthylic acid in culture medium at a high yield and concentration rate.
