METHOD FOR PREPARING XANTHOSINE 5'-MONOPHOSPHATE, STRAIN CORYNEBACTERIUM AMMONIAGENES AS PRODUCER OF XANTHOSINE 5'-MONOPHOSPHATE (VARIANTS)

摘要

FIELD: biotechnology, biochemistry, microbiology. SUBSTANCE: xanthosine 5'-monophosphate is prepared by fermentation method that involves culturing corynebacterium as a producer of xanthosine 5'-monophosphate in nutrient medium and its isolation from cultural fluid. Strains of bacterium Corynebacterium ammoniagenes (variants) exhibiting resistance against the growth suppression by inhibitor effect are used as producers. EFFECT: improved preparing method. 10 cl, 7 tbl
